Adds the main PLL clock groups for SOCFPGA into device tree file
so that the clock framework to query the clock and clock rates
appropriately.

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.
|
|
- 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.
