This patch adds bindings for i.MX8qxp/qm Display Prefetch Resolve Gasket. Reviewed-by: Rob Herring <robh@xxxxxxxxxx> Signed-off-by: Liu Ying <victor.liu@xxxxxxx> --- Note that this depends on the 'two cell binding' clock patch set which has already landed in Shawn's i.MX clk/imx git branch. Otherwise, imx8-lpcg.h won't be found. v3->v4: * Improve compatible property by using enum instead of oneOf+const. (Rob) * Add Rob's R-b tag. v2->v3: * No change. v1->v2: * Use new dt binding way to add clocks in the example. .../bindings/display/imx/fsl,imx8qxp-prg.yaml | 60 ++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-prg.yaml diff --git a/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-prg.yaml b/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-prg.yaml new file mode 100644 index 00000000..3ff46e0 --- /dev/null +++ b/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-prg.yaml @@ -0,0 +1,60 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/imx/fsl,imx8qxp-prg.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Freescale i.MX8qm/qxp Display Prefetch Resolve Gasket + +maintainers: + - Liu Ying <victor.liu@xxxxxxx> + +description: | + The i.MX8qm/qxp Prefetch Resolve Gasket (PRG) is a gasket interface between + RTRAM controller and Display Controller.
