1 Binding for Texas Instruments APLL clock.
3 Binding status: Unstable - ABI compatibility may be broken in the future
5 This binding uses the common clock binding[1]. It assumes a
6 register-mapped APLL with usually two selectable input clocks
7 (reference clock and bypass clock), with analog phase locked
8 loop logic for multiplying the input clock to a desired output
9 clock. This clock also typically supports different operation
10 modes (locked, low power stop etc.) APLL mostly behaves like
11 a subtype of a DPLL [2], although a simplified one at that.

17 - compatible : shall be "ti,dra7-apll-clock" or "ti,omap2-apll-clock"
18 - #clock-cells : from common clock binding; shall be set to 0.
19 - clocks : link phandles of parent clocks (clk-ref and clk-bypass)
20 - reg : address and length of the register set for controlling the APLL.
21 It contains the information of registers in the following order:
22 "control" - contains the control register offset
23 "idlest" - contains the idlest register offset
24 "autoidle" - contains the autoidle register offset (OMAP2 only)
25 - ti,clock-frequency : static clock frequency for the clock (OMAP2 only)
26 - ti,idlest-shift : bit-shift for the idlest field (OMAP2 only)
27 - ti,bit-shift : bit-shift for enable and autoidle fields (OMAP2 only)
