From 1435dc1f39aa8fe0a1f2091bbb95d6c247bd1e72 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Mon, 13 May 2024 17:20:46 +0800 Subject: dt-bindings: pinctrl: imx: Support i.MX91 IOMUXC i.MX91 and i.MX93 share similar design. They could share same dt-binding doc, so rename fsl,imx93-pinctrl.yaml to fsl,imx9-pinctrl.yaml and add i.MX91 compatible string Signed-off-by: Peng Fan Acked-by: Conor Dooley Link: https://lore.kernel.org/r/20240513-imx91-pinctrl-v1-1-c99a23c6843a@nxp.com Signed-off-by: Linus Walleij --- .../bindings/pinctrl/fsl,imx9-pinctrl.yaml | 87 ++++++++++++++++++++++ .../bindings/pinctrl/fsl,imx93-pinctrl.yaml | 85 --------------------- 2 files changed, 87 insertions(+), 85 deletions(-) create mode 100644 Documentation/devicetree/bindings/pinctrl/fsl,imx9-pinctrl.yaml delete mode 100644 Documentation/devicetree/bindings/pinctrl/fsl,imx93-pinctrl.yaml diff --git a/Documentation/devicetree/bindings/pinctrl/fsl,imx9-pinctrl.yaml b/Documentation/devicetree/bindings/pinctrl/fsl,imx9-pinctrl.yaml new file mode 100644 index 000000000000..a438db8884f2 --- /dev/null +++ b/Documentation/devicetree/bindings/pinctrl/fsl,imx9-pinctrl.yaml @@ -0,0 +1,87 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pinctrl/fsl,imx9-pinctrl.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Freescale IMX9 IOMUX Controller + +maintainers: + - Peng Fan + +description: + Please refer to fsl,imx-pinctrl.txt and pinctrl-bindings.txt in this directory + for common binding part and usage. + +allOf: + - $ref: pinctrl.yaml# + +properties: + compatible: + enum: + - fsl,imx91-iomuxc + - fsl,imx93-iomuxc + + reg: + maxItems: 1 + +# Client device subnode's properties +patternProperties: + 'grp$': + type: object + description: + Pinctrl node's client devices use subnodes for desired pin configuration. + Client device subnodes use below standard properties. + + properties: + fsl,pins: + description: + each entry consists of 6 integers and represents the mux and config + setting for one pin.
