Device Tree Clock bindings for Altera's SoCFPGA platform
|
|
|
|
This binding uses the common clock binding[1].
|
|
|
|
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
Required properties:
|
|
- compatible : shall be one of the following:
|
|
"altr,socfpga-pll-clock" - for a PLL clock
|
|
"altr,socfpga-perip-clock" - The peripheral clock divided from the
|
|
PLL clock.
|
|
"altr,socfpga-gate-clk" - Clocks that directly feed peripherals and
|
|
can get gated.
|
|
|
|
- reg : shall be the control register offset from CLOCK_MANAGER's base for the clock.
|
|
- clocks : shall be the input parent clock phandle for the clock. This is
|
|
either an oscillator or a pll output.
|
|
- #clock-cells : from common clock binding, shall be set to 0.
|
|
|
|
Optional properties:
|
|
- fixed-divider : If clocks have a fixed divider value, use this property.
|
|
- clk-gate : For "socfpga-gate-clk", clk-gate contains the gating register
|
|
and the bit index.
|
|
- div-reg : For "socfpga-gate-clk", div-reg contains the divider register, bit shift,
|
|
and width.
