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 one of the following,
16	"brcm,bcm2711-cprman"
17	"brcm,bcm2835-cprman"
18- #clock-cells:	Should be <1>. The permitted clock-specifier values can be
19		  found in include/dt-bindings/clock/bcm2835.h
20- reg:		Specifies base physical address and size of the registers
21- clocks:	phandles to the parent clocks used as input to the module, in
22		  the following order:
23
24		  - External oscillator
25		  - DSI0 byte clock
26		  - DSI0 DDR2 clock
27		  - DSI0 DDR clock
28		  - DSI1 byte clock
29		  - DSI1 DDR2 clock
30		  - DSI1 DDR clock
31
32		  Only external oscillator is required.  The DSI clocks may
33		  not be present, in which case their children will be
34		  unusable.

36Example:
37
38	clk_osc: clock@3 {
39		compatible = "fixed-clock";
40		reg = <3>;
41		#clock-cells = <0>;
42		clock-output-names = "osc";
43		clock-frequency = <19200000>;
44	};
45
46	clocks: cprman@7e101000 {
47		compatible = "brcm,bcm2835-cprman";
48		#clock-cells = <1>;
49		reg = <0x7e101000 0x2000>;
50		clocks = <&clk_osc>;
51	};
52
53	i2c0: i2c@7e205000 {
54		compatible = "brcm,bcm2835-i2c";
55		reg = <0x7e205000 0x1000>;
56		interrupts = <2 21>;
57		clocks = <&clocks BCM2835_CLOCK_VPU>;
58		#address-cells = <1>;
59		#size-cells = <0>;
60	};
