This binding uses the common clock binding[1]. It assumes a
register-mapped APLL with usually two selectable input clocks
(reference clock and bypass clock), with analog phase locked
loop logic for multiplying the input clock to a desired output
clock. This clock also typically supports different operation
modes (locked, low power stop etc.) APLL mostly behaves like
a subtype of a DPLL [2], although a simplified one at that.
Required properties:
- compatible : shall be "ti,dra7-apll-clock" or "ti,omap2-apll-clock"
- #clock-cells : from common clock binding; shall be set to 0.
- clocks : link phandles of parent clocks (clk-ref and clk-bypass)
- reg : address and length of the register set for controlling the APLL.
It contains the information of registers in the following order:
"control" - contains the control register offset
"idlest" - contains the idlest register offset
"autoidle" - contains the autoidle register offset (OMAP2 only)
- ti,clock-frequency : static clock frequency for the clock (OMAP2 only)
- ti,idlest-shift : bit-shift for the idlest field (OMAP2 only)
- ti,bit-shift : bit-shift for enable and autoidle fields (OMAP2 only)
