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 "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>; };
