The Samsung SoC UART nodes have usually DMA so dtschema has to reflect this to fix dtbs_check warnings like: arch/arm/boot/dts/exynos4210-smdkv310.dt.yaml: serial@13800000: 'dma-names', 'dmas' do not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> --- .../devicetree/bindings/serial/samsung_uart.yaml | 10 ++++++++++ 1 file changed, 10 insertions(+)
