Signed-off-by: Neeraj Sanjay Kale <neeraj.sanjaykale@xxxxxxx> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- v2: Resolved dt_binding_check errors. (Rob Herring) v2: Modified description, added specific compatibility devices, corrected indentations. (Krzysztof Kozlowski) v3: Modified description, renamed file (Krzysztof Kozlowski) v4: Resolved dt_binding_check errors, corrected indentation. (Rob Herring, Krzysztof Kozlowski) v5: Corrected serial device name in example.
