i.MX8qxp Display Controller display engine consists of all processing units that operate in a display clock domain. Signed-off-by: Liu Ying <victor.liu@xxxxxxx> --- v7: * Drop DT alias documentations and add instance numbers to compatible strings. (Rob) v6: * No change. v5: * Document aliases. Drop Rob's previous R-b tag. (Maxime) v4: * Collect Rob's R-b tag. v3: * No change. v2: * Drop fsl,dc-*-id DT properties. (Krzysztof) * Drop port property. (Krzysztof) * Fix register range sizes in example. .../imx/fsl,imx8qxp-dc-display-engine0.yaml | 235 ++++++++++++++++++ 1 file changed, 235 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-dc-display-engine0.yaml diff --git a/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-dc-display-engine0.yaml b/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-dc-display-engine0.yaml new file mode 100644 index 000000000000..60d1e0a4a5dd --- /dev/null +++ b/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-dc-display-engine0.yaml @@ -0,0 +1,235 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/imx/fsl,imx8qxp-dc-display-engine0.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Freescale i.MX8qxp Display Controller Display Engine + +description: + All Processing Units that operate in a display clock domain.
