+description: |
+ The i.MX8qm/qxp Prefetch Resolve Gasket (PRG) is a gasket interface between
+ RTRAM controller and Display Controller. The main function is to convert
+ the AXI interface to the RTRAM interface, which includes re-mapping the
+ ARADDR to a RTRAM address.

This patch adds bindings for i.MX8qxp/qm Display Prefetch Resolve Gasket. Signed-off-by: Liu Ying <victor.liu@nxp.com> --- 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. 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
