You can't ever remove them because you can't ever be sure that people won't be using an old DTB. > > Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx> > --- > Documentation/devicetree/bindings/drm/msm/hdmi.txt | 22 +++++++++++++++++----- > 1 file changed, 17 insertions(+), 5 deletions(-) > > diff --git a/Documentation/devicetree/bindings/drm/msm/hdmi.txt b/Documentation/devicetree/bindings/drm/msm/hdmi.txt > index c43aa53..acba581 100644 > --- a/Documentation/devicetree/bindings/drm/msm/hdmi.txt > +++ b/Documentation/devicetree/bindings/drm/msm/hdmi.txt > @@ -11,15 +11,27 @@ Required properties: > - interrupts: The interrupt signal from the hdmi block. > - clocks: device clocks > See ../clocks/clock-bindings.txt for details. > -- qcom,hdmi-tx-ddc-clk-gpio: ddc clk pin > -- qcom,hdmi-tx-ddc-data-gpio: ddc data pin > -- qcom,hdmi-tx-hpd-gpio: hpd pin > +- qcom,hdmi-tx-ddc-clk-gpios: ddc clk pin > +- qcom,hdmi-tx-ddc-data-gpios: ddc data pin > +- qcom,hdmi-tx-hpd-gpios: hpd pin > - core-vdda-supply: phandle to supply regulator > - hdmi-mux-supply: phandle to mux regulator > > +- qcom,hdmi-tx-ddc-clk-gpio: (deprecated) use > + "qcom,hdmi-tx-ddc-clk-gpios" instead > +- qcom,hdmi-tx-ddc-data-gpio: (deprecated) use > + "qcom,hdmi-tx-ddc-data-gpios" instead > +- qcom,hdmi-tx-hpd-gpio: (deprecated) use > + "qcom,hdmi-tx-hpd-gpios" instead > + > Optional properties: > -- qcom,hdmi-tx-mux-en-gpio: hdmi mux enable pin > -- qcom,hdmi-tx-mux-sel-gpio: hdmi mux select pin > +- qcom,hdmi-tx-mux-en-gpios: hdmi mux enable pin > +- qcom,hdmi-tx-mux-sel-gpios: hdmi mux select pin > + > +- qcom,hdmi-tx-mux-en-gpio: (deprecated) use "qcom,hdmi-tx-mux-en-gpios" > + instead > +- qcom,hdmi-tx-mux-sel-gpio: (deprecated) use "qcom,hdmi-tx-mux-sel-gpio" > + instead > - pinctrl-names: the pin control state names; should contain "default" > - pinctrl-0: the default pinctrl state (active) > - pinctrl-1: the "sleep" pinctrl state I don't see much use in listing that these properties are deprecated. We already have code to catch the deprecated names, so having them in the binding will at best be distracting. Anyway, I don't know if there's been any advice on this from the device tree bindings maintainers, so adding devicetree@xxxxxxxxxxxxxxx for visibility. Thierry
