DP DMA has own power domain that's why describe required power-domain property. Signed-off-by: Michal Simek <michal.simek@amd.com> --- Changes in v3: - make power-domains as required property - also update commit message Changes in v2: - rewrite commit message - requested by Krzysztof The commit b06112cd5e08 ("arm64: dts: zynqmp: Add power domain for the DisplayPort DMA controller") added this property already in Linux that's why the patch is also fixing dts_check warnings. In v2 I got ack from Krzysztof but not adding it because of additional discussion about required property in v3. https://lore.kernel.org/r/029ba923-d13e-ea7c-018d-95e179dda2e5@linaro.org --- .../devicetree/bindings/dma/xilinx/xlnx,zynqmp-dpdma.yaml | 6 ++++++ 1 file changed, 6 insertions(+)
