+Common leds properties.
+
+Optional properties for child nodes:
+- label : The label for this LED. If omitted, the label is
+ taken from the node name (excluding the unit address).
+
+- linux,default-trigger : This parameter, if present, is a
+ string defining the trigger assigned to the LED. Current triggers are:
+ "backlight" - LED will act as a back-light, controlled by the framebuffer
+ system
+ "default-on" - LED will turn on (but for leds-gpio see "default-state"
+ property in Documentation/devicetree/bindings/gpio/led.txt)
+ "heartbeat" - LED "double" flashes at a load average based rate
+ "ide-disk" - LED indicates disk activity
+ "timer" - LED flashes at a fixed, configurable rate
+
+Examples:
+
+system-status {
+ label = "Status";
+ linux,default-trigger = "heartbeat";
+ ...
+};
--- /dev/null
+LEDs connected to GPIO lines
+
+Required properties:
+- compatible : should be "gpio-leds".
+
+Each LED is represented as a sub-node of the gpio-leds device. Each
+node's name represents the name of the corresponding LED.
+
+LED sub-node properties:
+- gpios : Should specify the LED's GPIO, see "gpios property" in
+ Documentation/devicetree/bindings/gpio/gpio.txt. Active low LEDs should be
+ indicated using flags in the GPIO specifier.
+- label : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+- linux,default-trigger : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+- default-state: (optional) The initial state of the LED. Valid
+ values are "on", "off", and "keep". If the LED is already on or off
+ and the default-state property is set the to same value, then no
+ glitch should be produced where the LED momentarily turns off (or
+ on). The "keep" setting will keep the LED at whatever its current
+ state is, without producing a glitch. The default is off if this
+ property is not present.
+
+Examples:
+
+leds {
+ compatible = "gpio-leds";
+ hdd {
+ label = "IDE Activity";
+ gpios = <&mcu_pio 0 1>; /* Active low */
+ linux,default-trigger = "ide-disk";
+ };
+
+ fault {
+ gpios = <&mcu_pio 1 0>;
+ /* Keep LED on if BIOS detected hardware fault */
+ default-state = "keep";
+ };
+};
+
+run-control {
+ compatible = "gpio-leds";
+ red {
+ gpios = <&mpc8572 6 0>;
+ default-state = "off";
+ };
+ green {
+ gpios = <&mpc8572 7 0>;
+ default-state = "on";
+ };
+};
Platform Data
-------------
+*** Note: platform data is the old way of doing things. It is
+*** basically a C structure which is passed to drivers to tell them about
+*** platform-specific settings like the address of its registers, bus
+*** speed, etc. Device tree is now the preferred way of handling this.
+*** Unless you have a good reason not to use device tree (the main one
+*** being you need serial support in SPL and don't have enough SRAM for
+*** the cut-down device tree and libfdt libraries) you should stay away
+*** from platform data.
+
Platform data is like Linux platform data, if you are familiar with that.
It provides the board-specific information to start up a device.
-----------
While platdata is useful, a more flexible way of providing device data is

+config CLK
+ bool "Enable clock driver support"
+ depends on DM
+ help
+ This allows drivers to be provided for clock generators, including
+ oscillators and PLLs. Devices can use a common clock API to request
+ a particular clock rate and check on available clocks. Clocks can
+ feed into other clocks in a tree structure, with multiplexers to
+ choose the source for each clock.
+
+config SPL_CLK_SUPPORT
+ bool "Enable clock support in SPL"
+ depends on CLK
+ help
+ The clock subsystem adds a small amount of overhead to the image.
+ If this is acceptable and you have a need to use clock drivers in
+ SPL, enable this option. It might provide a cleaner interface to
+ setting up clocks within SPL, and allows the same drivers to be
+ used as U-Boot proper.

+/**
+ * fdt_first_region() - find regions in device tree
+ *
+ * Given a nodes and properties to include and properties to exclude, find
+ * the regions of the device tree which describe those included parts.
+ *
+ * The use for this function is twofold. Firstly it provides a convenient
+ * way of performing a structure-aware grep of the tree. For example it is
+ * possible to grep for a node and get all the properties associated with
+ * that node. Trees can be subsetted easily, by specifying the nodes that
+ * are required, and then writing out the regions returned by this function.
+ * This is useful for small resource-constrained systems, such as boot
+ * loaders, which want to use an FDT but do not need to know about all of
+ * it.
+ *
+ * Secondly it makes it easy to hash parts of the tree and detect changes.
+ * The intent is to get a list of regions which will be invariant provided
+ * those parts are invariant. For example, if you request a list of regions
+ * for all nodes but exclude the property "data", then you will get the
+ * same region contents regardless of any change to "data" properties.
+ *
+ * This function can be used to produce a byte-stream to send to a hashing
+ * function to verify that critical parts of the FDT have not changed.
+ * Note that semantically null changes in order could still cause false
+ * hash misses. Such reordering might happen if the tree is regenerated
+ * from source, and nodes are reordered (the bytes-stream will be emitted
+ * in a different order and mnay hash functions will detect this). However
+ * if an existing tree is modified using libfdt functions, such as
+ * fdt_add_subnode() and fdt_setprop(), then this problem is avoided.
+ *
+ * The nodes/properties to include/exclude are defined by a function
+ * provided by the caller. This function is called for each node and
+ * property, and must return:
+ *
+ * 0 - to exclude this part
+ * 1 - to include this part
+ * -1 - for FDT_IS_PROP only: no information is available, so include
+ * if its containing node is included
+ *
+ * The last case is only used to deal with properties. Often a property is
+ * included if its containing node is included - this is the case where
+ * -1 is returned.. However if the property is specifically required to be
+ * included/excluded, then 0 or 1 can be returned. Note that including a
+ * property when the FDT_REG_SUPERNODES flag is given will force its
+ * containing node to be included since it is not valid to have a property
+ * that is not in a node.
+ *
+ * Using the information provided, the inclusion of a node can be controlled
+ * either by a node name or its compatible string, or any other property
+ * that the function can determine.
+ *
+ * As an example, including node "/" means to include the root node and all
+ * root properties. A flag provides a way of also including supernodes (of
+ * which there is none for the root node), and another flag includes
+ * immediate subnodes, so in this case we would get the FDT_BEGIN_NODE and
+ * FDT_END_NODE of all subnodes of /.

+ * The subnode feature helps in a hashing situation since it prevents the
+ * root node from changing at all. Any change to non-excluded properties,
+ * names of subnodes or number of subnodes would be detected.
+ *
+ * When used with FITs this provides the ability to hash and sign parts of
+ * the FIT based on different configurations in the FIT. Then it is
+ * impossible to change anything about that configuration (include images
+ * attached to the configuration), but it may be possible to add new
+ * configurations, new images or new signatures within the existing
+ * framework.
+ *
+ * Adding new properties to a device tree may result in the string table
+ * being extended (if the new property names are different from those
+ * already added). This function can optionally include a region for
+ * the string table so that this can be part of the hash too. This is always
+ * the last region.
+ *
+ * The FDT also has a mem_rsvmap table which can also be included, and is
+ * always the first region if so.
+ *

+ * contents of the FDT are changing (shrinking, often), the caller will need
+ * to regenerate the header anyway.

+ * -----------------------------

+ * Version: C, Version 2.1
+ *
+ * File: dhry.h (part 1 of 3)

+ *
+ * Original Version (in Ada) published in
+ * "Communications of the ACM" vol. 27., no. 10 (Oct. 1984),
+ * pp. 1013 - 1030, together with the statistics
+ * on which the distribution of statements etc. is based.
+ *
+ * In this C version, the following C library functions are used:
+ * - strcpy, strcmp (inside the measurement loop)
+ * - printf, scanf (outside the measurement loop)
+ * In addition, Berkeley UNIX system calls "times ()" or "time ()"
+ * are used for execution time measurement. For measurements
+ * on other systems, these calls have to be changed.

+ * Usenet: ...!seismo!uunet!pcrat!rick
+ *
+ * Please send results to Rick Richardson and/or Reinhold Weicker.
+ * Complete information should be given on hardware and software used.
+ * Hardware information includes: Machine type, CPU, type and size
+ * of caches; for microprocessors: clock frequency, memory speed
+ * (number of wait states).
+ * Software information includes: Compiler (and runtime library)
+ * manufacturer and version, compilation switches, OS version.
+ * The Operating System version may give an indication about the
+ * compiler; Dhrystone itself performs no OS calls in the measurement loop.
+ *
+ * The complete output generated by the program should be mailed
+ * such that at least some checks for correctness can be made.
+ *
+ ***************************************************************************
+ *
+ * History: This version C/2.1 has been made for two reasons:
+ *
+ * 1) There is an obvious need for a common C version of
+ * Dhrystone, since C is at present the most popular system
+ * programming language for the class of processors
+ * (microcomputers, minicomputers) where Dhrystone is used most.
+ * There should be, as far as possible, only one C version of
+ * Dhrystone such that results can be compared without
+ * restrictions. In the past, the C versions distributed
+ * by Rick Richardson (Version 1.1) and by Reinhold Weicker
+ * had small (though not significant) differences.
+ *
+ * 2) As far as it is possible without changes to the Dhrystone
+ * statistics, optimizing compilers should be prevented from
+ * removing significant statements.
+ *
+ * This C version has been developed in cooperation with
+ * Rick Richardson (Tinton Falls, NJ), it incorporates many
+ * ideas from the "Version 1.1" distributed previously by
+ * him over the UNIX network Usenet.
+ * I also thank Chaim Benedelac (National Semiconductor),
+ * David Ditzel (SUN), Earl Killian and John Mashey (MIPS),
+ * Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley)
+ * for their help with comments on earlier versions of the
+ * benchmark.
+ *
+ * Changes: In the initialization part, this version follows mostly
+ * Rick Richardson's version distributed via Usenet, not the
+ * version distributed earlier via floppy disk by Reinhold Weicker.
+ * As a concession to older compilers, names have been made
+ * unique within the first 8 characters.
+ * Inside the measurement loop, this version follows the
+ * version previously distributed by Reinhold Weicker.
+ *
+ * At several places in the benchmark, code has been added,
+ * but within the measurement loop only in branches that
+ * are not executed. The intention is that optimizing compilers
+ * should be prevented from moving code out of the measurement
+ * loop, or from removing code altogether. Since the statements
+ * that are executed within the measurement loop have NOT been
+ * changed, the numbers defining the "Dhrystone distribution"
+ * (distribution of statements, operand types and locality)
+ * still hold. Except for sophisticated optimizing compilers,
+ * execution times for this version should be the same as
+ * for previous versions.
+ *
+ * Since it has proven difficult to subtract the time for the
+ * measurement loop overhead in a correct way, the loop check
+ * has been made a part of the benchmark. This does have
+ * an impact - though a very minor one - on the distribution
+ * statistics which have been updated for this version.
+ *
+ * All changes within the measurement loop are described
+ * and discussed in the companion paper "Rationale for
+ * Dhrystone version 2".
+ *
+ * Because of the self-imposed limitation that the order and
+ * distribution of the executed statements should not be
+ * changed, there are still cases where optimizing compilers
+ * may not generate code for some statements. To a certain
+ * degree, this is unavoidable for small synthetic benchmarks.
+ * Users of the benchmark are advised to check code listings
+ * whether code is generated for all statements of Dhrystone.
+ *
+ * Version 2.1 is identical to version 2.0 distributed via
+ * the UNIX network Usenet in March 1988 except that it corrects
+ * some minor deficiencies that were found by users of version 2.0.
+ * The only change within the measurement loop is that a
+ * non-executed "else" part was added to the "if" statement in
+ * Func_3, and a non-executed "else" part removed from Proc_3.
+ *
+ ***************************************************************************
+ *
+ * Defines: The following "Defines" are possible:
+ * -DREG=register (default: Not defined)
+ * As an approximation to what an average C programmer
+ * might do, the "register" storage class is applied
+ * (if enabled by -DREG=register)
+ * - for local variables, if they are used (dynamically)
+ * five or more times
+ * - for parameters if they are used (dynamically)
+ * six or more times
+ * Note that an optimal "register" strategy is
+ * compiler-dependent, and that "register" declarations
+ * do not necessarily lead to faster execution.
+ * -DNOSTRUCTASSIGN (default: Not defined)
+ * Define if the C compiler does not support
+ * assignment of structures.
+ * -DNOENUMS (default: Not defined)
+ * Define if the C compiler does not support
+ * enumeration types.
+ * -DTIMES (default)
+ * -DTIME
+ * The "times" function of UNIX (returning process times)
+ * or the "time" function (returning wallclock time)
+ * is used for measurement.
+ * For single user machines, "time ()" is adequate. For
+ * multi-user machines where you cannot get single-user
+ * access, use the "times ()" function. If you have
+ * neither, use a stopwatch in the dead of night.
+ * "printf"s are provided marking the points "Start Timer"
+ * and "Stop Timer". DO NOT use the UNIX "time(1)"
+ * command, as this will measure the total time to
+ * run this program, which will (erroneously) include
+ * the time to allocate storage (malloc) and to perform
+ * the initialization.
+ * -DHZ=nnn
+ * In Berkeley UNIX, the function "times" returns process
+ * time in 1/HZ seconds, with HZ = 60 for most systems.
+ * CHECK YOUR SYSTEM DESCRIPTION BEFORE YOU JUST APPLY
+ * A VALUE.
+ *
+ ***************************************************************************
+ *
+ * Compilation model and measurement (IMPORTANT):
+ *
+ * This C version of Dhrystone consists of three files:
+ * - dhry.h (this file, containing global definitions and comments)
+ * - dhry_1.c (containing the code corresponding to Ada package Pack_1)
+ * - dhry_2.c (containing the code corresponding to Ada package Pack_2)
+ *
+ * The following "ground rules" apply for measurements:
+ * - Separate compilation
+ * - No procedure merging
+ * - Otherwise, compiler optimizations are allowed but should be indicated
+ * - Default results are those without register declarations
+ * See the companion paper "Rationale for Dhrystone Version 2" for a more
+ * detailed discussion of these ground rules.
+ *
+ * For 16-Bit processors (e.g. 80186, 80286), times for all compilation
+ * models ("small", "medium", "large" etc.) should be given if possible,
+ * together with a definition of these models for the compiler system used.

+/*
+ * Theory of operation
+ *
+ *
+ *
+
+Note: in this description 'included' means that a node (or other part of
+the tree) should be included in the region list, i.e. it will have a region
+which covers its part of the tree.
+
+This function maintains some state from the last time it is called. It
+checks the next part of the tree that it is supposed to look at
+(p.nextoffset) to see if that should be included or not. When it finds
+something to include, it sets info->start to its offset. This marks the
+start of the region we want to include.
+
+Once info->start is set to the start (i.e. not -1), we continue scanning
+until we find something that we don't want included. This will be the end
+of a region. At this point we can close off the region and add it to the
+list. So we do so, and reset info->start to -1.
+
+One complication here is that we want to merge regions. So when we come to
+add another region later, we may in fact merge it with the previous one if
+one ends where the other starts.
+
+The function fdt_add_region() will return -1 if it fails to add the region,
+because we already have a region ready to be returned, and the new one
+cannot be merged in with it. In this case, we must return the region we
+found, and wait for another call to this function. When it comes, we will
+repeat the processing of the tag and again try to add a region. This time it
+will succeed.
+
+The current state of the pointers (stack, offset, etc.) is maintained in
+a ptrs member. At the start of every loop iteration we make a copy of it.
+The copy is then updated as the tag is processed. Only if we get to the end
+of the loop iteration (and successfully call fdt_add_region() if we need
+to) can we commit the changes we have made to these pointers. For example,
+if we see an FDT_END_NODE tag we will decrement the depth value. But if we
+need to add a region for this tag (let's say because the previous tag is
+included and this FDT_END_NODE tag is not included) then we will only commit
+the result if we were able to add the region. That allows us to retry again
+next time.
+
+We keep track of a variable called 'want' which tells us what we want to
+include when there is no specific information provided by the h_include
+function for a particular property. This basically handles the inclusion of
+properties which are pulled in by virtue of the node they are in. So if you
+include a node, its properties are also included. In this case 'want' will
+be WANT_NODES_AND_PROPS. The FDT_REG_DIRECT_SUBNODES feature also makes use
+of 'want'. While we are inside the subnode, 'want' will be set to
+WANT_NODES_ONLY, so that only the subnode's FDT_BEGIN_NODE and FDT_END_NODE
+tags will be included, and properties will be skipped. If WANT_NOTHING is
+selected, then we will just rely on what the h_include() function tells us.
+
+Using 'want' we work out 'include', which tells us whether this current tag
+should be included or not. As you can imagine, if the value of 'include'
+changes, that means we are on a boundary between nodes to include and nodes
+to exclude. At this point we either close off a previous region and add it
+to the list, or mark the start of a new region.
+
+Apart from the nodes, we have mem_rsvmap, the FDT_END tag and the string
+list. Each of these dealt with as a whole (i.e. we create a region for each
+if it is to be included). For mem_rsvmap we don't allow it to merge with
+the first struct region. For the stringlist we don't allow it to merge with
+the last struct region (which contains at minimum the FDT_END tag).
