+STMicroelectronics STM32H7 Reset and Clock Controller
+=====================================================
+
+The RCC IP is both a reset and a clock controller.
+
+Please refer to clock-bindings.txt for common clock controller binding usage.
+Please also refer to reset.txt for common reset controller binding usage.
+
+Required properties:
+- compatible: Should be:
+ "st,stm32h743-rcc"
+
+- reg: should be register base and length as documented in the
+ datasheet
+
+- #reset-cells: 1, see below
+
+- #clock-cells : from common clock binding; shall be set to 1
+
+- clocks: External oscillator clock phandle
+ - high speed external clock signal (HSE)
+ - low speed external clock signal (LSE)
+ - external I2S clock (I2S_CKIN)
+
+- st,syscfg: phandle for pwrcfg, mandatory to disable/enable backup domain
+ write protection (RTC clock).
+
+- pll x node: Allow to register a pll with specific parameters.
+ Please see PLL section below.
+
+Example:
+
+ rcc: rcc@58024400 {
+ #reset-cells = <1>;
+ #clock-cells = <2>
+ compatible = "st,stm32h743-rcc", "st,stm32-rcc";
+ reg = <0x58024400 0x400>;
+ clocks = <&clk_hse>, <&clk_lse>, <&clk_i2s_ckin>;
+
+ st,syscfg = <&pwrcfg>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ vco1@58024430 {
+ #clock-cells = <0>;
+ compatible = "stm32,pll";
+ reg = <0>;
+ };
+
+ vco2@58024438 {
+ #clock-cells = <0>;
+ compatible = "stm32,pll";
+ reg = <1>;
+ st,clock-div = <2>;
+ st,clock-mult = <40>;
+ st,frac-status = <0>;
+ st,frac = <0>;
+ st,vcosel = <1>;
+ st,pllrge = <2>;
+ };
+ };
+
+
+STM32H7 PLL
+-----------
+
+The VCO of STM32 PLL could be reprensented like this:
+
+ Vref --------- --------
+ ---->| / DIVM |---->| x DIVN | ------> VCO
+ --------- --------
+ ^
+ |
+ -------
+ | FRACN |
+ -------
+
+When the PLL is configured in integer mode:
+- VCO = ( Vref / DIVM ) * DIVN
+
+When the PLL is configured in fractional mode:
+- VCO = ( Vref / DIVM ) * ( DIVN + FRACN / 2^13)
+
+
+Required properties for pll node:
+- compatible: Should be:
+ "stm32,pll"
+
+- #clock-cells: from common clock binding; shall be set to 0
+- reg: Should be the pll number.
+
+Optional properties:
+- st,clock-div: DIVM division factor : <1..63>
+- st,clock-mult: DIVN multiplication factor : <4..512>
+
+- st,frac-status:
+ - 0 Pll is configured in integer mode
+ - 1 Pll is configure in fractional mode
+
+- st,frac: Fractional part of the multiplication factor : <0..8191>
+
+- st,vcosel: VCO selection
+ - 0: Wide VCO range:192 to 836 MHz
+ - 1: Medium VCO range:150 to 420 MHz
+
+- st,pllrge: PLL input frequency range
+ - 0: The PLL input (Vref / DIVM) clock range frequency is between 1 and 2 MHz
+ - 1: The PLL input (Vref / DIVM) clock range frequency is between 2 and 4 MHz
+ - 2: The PLL input (Vref / DIVM) clock range frequency is between 4 and 8 MHz
+ - 3: The PLL input (Vref / DIVM) clock range frequency is between 8 and 16 MHz
+
+
+The peripheral clock consumer should specify the desired clock by
+having the clock ID in its "clocks" phandle cell.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/stm32h7-clks.h header and can be used in device
+tree sources.
+
+Example:
+
+ timer5: timer@40000c00 {
+ compatible = "st,stm32-timer";
+ reg = <0x40000c00 0x400>;
+ interrupts = <50>;
+ clocks = <&rcc TIM5_CK>;
+
+ };
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the reset device node and an index specifying
+which channel to use.
+The index is the bit number within the RCC registers bank, starting from RCC
+base address.
+It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+Where bit_offset is the bit offset within the register.
+
+For example, for CRC reset:
+ crc = AHB4RSTR_offset / 4 * 32 + CRCRST_bit_offset = 0x88 / 4 * 32 + 19 = 1107
+
+All available preprocessor macros for reset are defined dt-bindings//mfd/stm32h7-rcc.h
+header and can be used in device tree sources.
+
+example:
+
+ timer2 {
+ resets = <&rcc STM32H7_APB1L_RESET(TIM2)>;
+ };

+ST STiH407 USB PHY controller
+
+This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3
+host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics.
+
+Required properties:
+- compatible : should be "st,stih407-usb2-phy"
+- st,syscfg : phandle of sysconfig bank plus integer array containing phyparam and phyctrl register offsets
+- resets : list of phandle and reset specifier pairs. There should be two entries, one
+ for the whole phy and one for the port
+- reset-names : list of reset signal names. Should be "global" and "port"
+See: Documentation/devicetree/bindings/reset/st,sti-powerdown.txt
+See: Documentation/devicetree/bindings/reset/reset.txt
+
+Example:
+
+usb2_picophy0: usbpicophy {
+ compatible = "st,stih407-usb2-phy";
+ #phy-cells = <0>;
+ st,syscfg = <&syscfg_core 0x100 0xf4>;
+ resets = <&softreset STIH407_PICOPHY_SOFTRESET>,
+ <&picophyreset STIH407_PICOPHY0_RESET>;
+ reset-names = "global", "port";

+ST DWC3 glue logic
+
+This file documents the parameters for the dwc3-st driver.
+This driver controls the glue logic used to configure the dwc3 core on
+STiH407 based platforms.
+
+Required properties:
+ - compatible : must be "st,stih407-dwc3"
+ - reg : glue logic base address and USB syscfg ctrl register offset
+ - reg-names : should be "reg-glue" and "syscfg-reg"
+ - st,syscon : should be phandle to system configuration node which
+ encompasses the glue registers
+ - resets : list of phandle and reset specifier pairs. There should be two entries, one
+ for the powerdown and softreset lines of the usb3 IP
+ - reset-names : list of reset signal names. Names should be "powerdown" and "softreset"
+
+ - #address-cells, #size-cells : should be '1' if the device has sub-nodes
+ with 'reg' property
+
+ - pinctl-names : A pinctrl state named "default" must be defined
+
+ - pinctrl-0 : Pin control group
+
+ - ranges : allows valid 1:1 translation between child's address space and
+ parent's address space
+
+Sub-nodes:
+The dwc3 core should be added as subnode to ST DWC3 glue as shown in the
+example below.
+
+NB: The dr_mode property is NOT optional for this driver, as the default value
+is "otg", which isn't supported by this SoC. Valid dr_mode values for dwc3-st are
+either "host" or "device".
+
+Example:
+
+st_dwc3: dwc3@8f94000 {
+ status = "disabled";
+ compatible = "st,stih407-dwc3";
+ reg = <0x08f94000 0x1000>, <0x110 0x4>;
+ reg-names = "reg-glue", "syscfg-reg";
+ st,syscfg = <&syscfg_core>;
+ resets = <&powerdown STIH407_USB3_POWERDOWN>,
+ <&softreset STIH407_MIPHY2_SOFTRESET>;
+ reset-names = "powerdown", "softreset";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_usb3>;
+ ranges;
+
+ dwc3: dwc3@9900000 {
+ compatible = "snps,dwc3";
+ reg = <0x09900000 0x100000>;
+ interrupts = <GIC_SPI 155 IRQ_TYPE_NONE>;
+ dr_mode = "host";
+ phy-names = "usb2-phy", "usb3-phy";
+ phys = <&usb2_picophy2>, <&phy_port2 PHY_TYPE_USB3>;

+# Simple script to update the version of DTC carried by the Linux kernel

+# This script assumes that the dtc and the linux git trees are in the
+# same directory. After building dtc in the dtc directory, it copies the
+# source files and generated source files into the scripts/dtc directory
+# in the kernel and creates a git commit updating them to the new
+# version.
+#
+# Usage: from the top level Linux source tree, run:
+# $ ./scripts/dtc/update-dtc-source.sh
+#
+# The script will change into the dtc tree, build and test dtc, copy the
+# relevant files into the kernel tree and create a git commit. The commit
+# message will need to be modified to reflect the version of DTC being
+# imported
+#
+# TODO:
+# This script is pretty basic, but it is seldom used so a few manual tasks
+# aren't a big deal. If anyone is interested in making it more robust, the
+# the following would be nice:
+# * Actually fail to complete if any testcase fails.
+# - The dtc "make check" target needs to return a failure
+# * Extract the version number from the dtc repo for the commit message
+# * Build dtc in the kernel tree
+# * run 'make check" on dtc built from the kernel tree
