Add new binding document for pinctrl on IPQ9574 Co-developed-by: Anusha Rao <quic_anusha@xxxxxxxxxxx> Signed-off-by: Anusha Rao <quic_anusha@xxxxxxxxxxx> Signed-off-by: Devi Priya <quic_devipriy@xxxxxxxxxxx> --- Changes in V7: - Updated the function enum names for mac, pta and pwm pins as they have been grouped in the pinctrl driver - Dropped the pin enum names as they are not used in the driver - Dropped the Reviewed-by tag due to the above changes .../bindings/pinctrl/qcom,ipq9574-tlmm.yaml | 130 ++++++++++++++++++ 1 file changed, 130 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/qcom,ipq9574-tlmm.yaml diff --git a/Documentation/devicetree/bindings/pinctrl/qcom,ipq9574-tlmm.yaml b/Documentation/devicetree/bindings/pinctrl/qcom,ipq9574-tlmm.yaml new file mode 100644 index 000000000000..f32239d08c32 --- /dev/null +++ b/Documentation/devicetree/bindings/pinctrl/qcom,ipq9574-tlmm.yaml @@ -0,0 +1,130 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pinctrl/qcom,ipq9574-tlmm.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm Technologies, Inc.
