[2] Documentation/devicetree/bindings/clock/ti/dpll.txt Required properties: -- compatible : shall be "ti,dra7-apll-clock" +- 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 base address - "idlest" - contains the idlest register base address + "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) Examples: - apll_pcie_ck: apll_pcie_ck@4a008200 { + apll_pcie_ck: apll_pcie_ck { #clock-cells = <0>; clocks = <&apll_pcie_in_clk_mux>, <&dpll_pcie_ref_ck>; - reg = <0x4a00821c 0x4>, <0x4a008220 0x4>; + reg = <0x021c>, <0x0220>; compatible = "ti,dra7-apll-clock"; }; + + apll96_ck: apll96_ck { + #clock-cells = <0>; + compatible = "ti,omap2-apll-clock"; + clocks = <&sys_ck>; + ti,bit-shift = <2>; + ti,idlest-shift = <8>; + ti,clock-frequency = <96000000>; + reg = <0x0500>, <0x0530>, <0x0520>; + }; |
