Add device tree bindings documentation for Qualcomm MSM8953 pinctrl driver. Signed-off-by: Vladimir Lypak <junak.pub@xxxxxxxxx> --- Changes in V2: - removed "wakeup-parent" property. - changed pincfg property pattern to '-pins$' and added its description. - added "serial-pins" subnode to example. --- .../pinctrl/qcom,msm8953-pinctrl.yaml | 167 ++++++++++++++++++ 1 file changed, 167 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/qcom,msm8953-pinctrl.yaml diff --git a/Documentation/devicetree/bindings/pinctrl/qcom,msm8953-pinctrl.yaml b/Documentation/devicetree/bindings/pinctrl/qcom,msm8953-pinctrl.yaml new file mode 100644 index 000000000000..abe9f4c9b1e3 --- /dev/null +++ b/Documentation/devicetree/bindings/pinctrl/qcom,msm8953-pinctrl.yaml @@ -0,0 +1,167 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pinctrl/qcom,msm8953-pinctrl.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm Technologies, Inc.
