We can not describe these properties as required since current DTs do not have them. Also if somebody decides to fix the mdm9615 or msm8660 platforms, he works have to change this (again). Thus I'd just leave this whole chunk out. > With a quick check I notice that all the other platform doesn't have pxo_board or PLL8_VOTE clk so they wouln't work with the current driver... to me it seems they are just exposing the kpss-gcc reg with syscon and they are used in the rpm driver... This is very similar to the acc-v1 and acc-v2 separation where acc-v2 only provide the reg and nothing else. Wonder if we should do the same here or add clk support only for the specific compatible as I did here... In both case dts changes are required and a similar chunk is necessary. > >+ > >+additionalProperties: false > >+ > >+examples: > >+ - | > >+ #include <dt-bindings/clock/qcom,gcc-ipq806x.h> > >+ > >+ clock-controller@2011000 { > >+ compatible = "qcom,kpss-gcc-ipq8064", "qcom,kpss-gcc", "syscon"; > >+ reg = <0x2011000 0x1000>; > >+ clocks = <&gcc PLL8_VOTE>, <&pxo_board>; > >+ clock-names = "pll8_vote", "pxo"; > >+ #clock-cells = <0>; > >+ }; > >+ > >+ - | > >+ clock-controller@2011000 { > >+ compatible = "qcom,kpss-gcc-mdm9615", "qcom,kpss-gcc", "syscon"; > >+ reg = <0x02011000 0x1000>; > >+ }; > >+... > >+ > > -- > With best wishes > Dmitry

Rework kpss-gcc driver Documentation to yaml Documentation. The current kpss-gcc Documentation have major problems and can't be converted directly. Introduce various changes to the original Documentation. Add #clock-cells additional binding as this clock outputs a static clk named acpu_l2_aux with supported compatible. Only some compatible require and outputs a clock, for the others, set only the reg as a required binding to correctly export the kpss-gcc registers. As the reg is shared also add the required syscon compatible.
