Subject: [PATCH 1/2] dt-bindings: serial: samsung: add DMA properties
Date: Fri, 12 Feb 2021 17:39:04 +0100 [thread overview]
Message-ID: <20210212163905.70171-1-krzk@kernel.org> (raw)
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>
