1Broadcom BCM2835 CPRMAN clocks
2
3This binding uses the common clock binding:
4    Documentation/devicetree/bindings/clock/clock-bindings.txt

6The CPRMAN clock controller generates clocks in the audio power domain
7of the BCM2835.  There is a level of PLLs deriving from an external
8oscillator, a level of PLL dividers that produce channels off of the
9few PLLs, and a level of mostly-generic clock generators sourcing from
10the PLL channels.  Most other hardware components source from the
11clock generators, but a few (like the ARM or HDMI) will source from
12the PLL dividers directly.

14Required properties:
15- compatible:	Should be "brcm,bcm2835-cprman"
16- #clock-cells:	Should be <1>. The permitted clock-specifier values can be
17		  found in include/dt-bindings/clock/bcm2835.h
18- reg:		Specifies base physical address and size of the registers
19- clocks:	phandles to the parent clocks used as input to the module, in
20		  the following order:
21
22		  - External oscillator
23		  - DSI0 byte clock
24		  - DSI0 DDR2 clock
25		  - DSI0 DDR clock
26		  - DSI1 byte clock
27		  - DSI1 DDR2 clock
28		  - DSI1 DDR clock
29
30		  Only external oscillator is required.  The DSI clocks may
31		  not be present, in which case their children will be
32		  unusable.

34Example:
35
36	clk_osc: clock@3 {
37		compatible = "fixed-clock";
38		reg = <3>;
39		#clock-cells = <0>;
40		clock-output-names = "osc";
41		clock-frequency = <19200000>;
42	};
43
44	clocks: cprman@7e101000 {
45		compatible = "brcm,bcm2835-cprman";
46		#clock-cells = <1>;
47		reg = <0x7e101000 0x2000>;
48		clocks = <&clk_osc>;
49	};
50
51	i2c0: i2c@7e205000 {
52		compatible = "brcm,bcm2835-i2c";
53		reg = <0x7e205000 0x1000>;
54		interrupts = <2 21>;
55		clocks = <&clocks BCM2835_CLOCK_VPU>;
56		#address-cells = <1>;
57		#size-cells = <0>;
58	};
