On dm814x we have 13 ADPLLs with 3 to 4 outputs on each. The ADPLLs have several dividers and muxes controlled by a shared control register for each PLL. Note that for the clocks to work as device drivers for booting on dm814x, this patch depends on "ARM: OMAP2+: Change core_initcall levels to postcore_initcall" that has already been merged. Also note that this patch does not implement clk_set_rate for the PLL, that will be posted later on when available.

Binding for Texas Instruments ADPLL clock.
|
|
|
|
Binding status: Unstable - ABI compatibility may be broken in the future
|
|
|
|
This binding uses the common clock binding[1]. It assumes a
|
|
register-mapped ADPLL with two to three selectable input clocks
|
|
and three to four children.
|
|
|
|
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
Required properties:
|
|
- compatible : shall be one of "ti,dm814-adpll-s-clock" or
|
|
"ti,dm814-adpll-lj-clock" depending on the type of the ADPLL
|
|
- #clock-cells : from common clock binding; shall be set to 1.
|
|
- clocks : link phandles of parent clocks clkinp and clkinpulow, note
|
|
that the adpll-s-clock also has an optional clkinphif
|
|
- reg : address and length of the register set for controlling the ADPLL.
|
|
|
|
Examples:
|
|
adpll_mpu_ck: adpll@40 {
|
|
#clock-cells = <1>;
|
|
compatible = "ti,dm814-adpll-s-clock";
|
|
reg = <0x40 0x40>;
|
|
clocks = <&devosc_ck &devosc_ck &devosc_ck>;
|
|
clock-names = "clkinp", "clkinpulow", "clkinphif";
|

clock-output-names = "481c5040.adpll.dcoclkldo",
