X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=100026f4b50718d4a730672a5b5eba48a72d0405;p=thirdparty%2Flinux.git

dt-bindings: clock: Convert brcm,bcm2835-cprman to DT schema

Convert the Broadcom BCM2835 CPRMAN clock binding to DT schema format.
It's a straight forward conversion.

-Broadcom BCM2835 CPRMAN clocks
-
-This binding uses the common clock binding:
-    Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-The CPRMAN clock controller generates clocks in the audio power domain
-of the BCM2835.  There is a level of PLLs deriving from an external
-oscillator, a level of PLL dividers that produce channels off of the
-few PLLs, and a level of mostly-generic clock generators sourcing from
-the PLL channels.  Most other hardware components source from the
-clock generators, but a few (like the ARM or HDMI) will source from
-the PLL dividers directly.
-
-Required properties:
-- compatible:	should be one of the following,
-	"brcm,bcm2711-cprman"
-	"brcm,bcm2835-cprman"
-- #clock-cells:	Should be <1>. The permitted clock-specifier values can be
-		  found in include/dt-bindings/clock/bcm2835.h
-- reg:		Specifies base physical address and size of the registers
-- clocks:	phandles to the parent clocks used as input to the module, in
-		  the following order:
-
-		  - External oscillator
-		  - DSI0 byte clock
-		  - DSI0 DDR2 clock
-		  - DSI0 DDR clock
-		  - DSI1 byte clock
-		  - DSI1 DDR2 clock
-		  - DSI1 DDR clock
-
-		  Only external oscillator is required.  The DSI clocks may
-		  not be present, in which case their children will be
-		  unusable.
-
-Example:
-
-	clk_osc: clock@3 {
-		compatible = "fixed-clock";
-		reg = <3>;
-		#clock-cells = <0>;
-		clock-output-names = "osc";
-		clock-frequency = <19200000>;
-	};
-
-	clocks: cprman@7e101000 {
-		compatible = "brcm,bcm2835-cprman";
-		#clock-cells = <1>;
-		reg = <0x7e101000 0x2000>;
-		clocks = <&clk_osc>;
-	};
-
-	i2c0: i2c@7e205000 {
-		compatible = "brcm,bcm2835-i2c";
-		reg = <0x7e205000 0x1000>;
-		interrupts = <2 21>;
-		clocks = <&clocks BCM2835_CLOCK_VPU>;
-		#address-cells = <1>;
-		#size-cells = <0>;
