Reviewed-by: Rob Herring Signed-off-by: Liu Ying --- v10->v14: * No change. v9->v10: * Add Rob's R-b tag. v8->v9: * Reference 'interrupts-extended' schema instead of 'interrupts' to require an additional interrupt(r_rtram_stall) because the reference manual does mention it, though the driver doesn't get/use it for now. Reference 'interrupt-names' schema to define the two interrupt names - 'dpr_wrap' and 'r_rtram_stall'. * Drop Rob's R-b tag, as review is needed. v4->v8: * No change. 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. .../display/imx/fsl,imx8qxp-dprc.yaml | 100 ++++++++++++++++++ 1 file changed, 100 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-dprc.yaml diff --git a/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-dprc.yaml b/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-dprc.yaml new file mode 100644 index 000000000000..bd94254c1288 --- /dev/null +++ b/Documentation/devicetree/bindings/display/imx/fsl,imx8qxp-dprc.yaml @@ -0,0 +1,100 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/imx/fsl,imx8qxp-dprc.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Freescale i.MX8qm/qxp Display Prefetch Resolve Channel + +maintainers: + - Liu Ying + +description: | + The i.MX8qm/qxp Display Prefetch Resolve Channel(DPRC) is an engine which + fetches display data before the display pipeline needs the data to drive + pixels in the active display region.
