1Broadcom BCM2835 CPRMAN clocks 2 3This binding uses the common clock binding: 4 Documentation/devicetree/bindings/clock/clock-bindings.txt 5 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. 13 14Required properties: 15- compatible: Should be "brcm,bcm2835-cprman" 16- #clock-cells: Should be <1>.
