1 Broadcom BCM2835 CPRMAN clocks
3 This binding uses the common clock binding:
4 Documentation/devicetree/bindings/clock/clock-bindings.txt
6 The CPRMAN clock controller generates clocks in the audio power domain
7 of the BCM2835. There is a level of PLLs deriving from an external
8 oscillator, a level of PLL dividers that produce channels off of the
9 few PLLs, and a level of mostly-generic clock generators sourcing from
10 the PLL channels. Most other hardware components source from the
11 clock generators, but a few (like the ARM or HDMI) will source from
12 the PLL dividers directly.
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
30 Only external oscillator is required. The DSI clocks may
31 not be present, in which case their children will be
