1Broadcom BCM2835 CPRMAN clocks2 3This binding uses the common clock binding:4 Documentation/devicetree/bindings/clock/clock-bindings.txt5 6The CPRMAN clock controller generates clocks in the audio power domain7of the BCM2835. There is a level of PLLs deriving from an external8oscillator, a level of PLL dividers that produce channels off of the9few PLLs, and a level of mostly-generic clock generators sourcing from10the PLL channels. Most other hardware components source from the11clock generators, but a few (like the ARM or HDMI) will source from12the PLL dividers directly.13 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 be19 found in include/dt-bindings/clock/bcm2835.h20- reg: Specifies base physical address and size of the registers21- clocks: phandles to the parent clocks used as input to the module, in22 the following order:23 24 - External oscillator25 - DSI0 byte clock26 - DSI0 DDR2 clock27 - DSI0 DDR clock28 - DSI1 byte clock29 - DSI1 DDR2 clock30 - DSI1 DDR clock31 32 Only external oscillator is required.
