Convert the UniPhier I2C controller (FIFO-less) binding to DT schema format. There are two types of I2C controllers used on the UniPhier platform. This is the legacy one without FIFO support, which is used on the sLD8 SoC or older. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> --- When I search for a subsystem-common schema, I need to look in both dt-schema project and the kernel tree. For example, the i2c-controller.yaml is located in the dt-schema project. dt-schema/schemas/i2c/i2c-controller.yaml The dma-controller.yaml is located in the kernel tree. Documentation/devicetree/bindings/dma/dma-controller.yaml I am still wondering about the policy... As far as I understood, the schema written by Rob tend to go in the dt-schma project.
