This converts the DT binding for the Analogix DP bridge used in the Exynos 5 and Rockchip RK3288/RK3399 SoCs to yaml.
Changes from the original binding: - phy and phy-names aren't defined as 'required' (rk3399-evb.dts doesn't define them)
Signed-off-by: Ricardo Cañuelo ricardo.canuelo@collabora.com --- This binding is meant to be used in conjunction with Documentation/bindings/display/rockchip/analogix_dp-rockchip.txt and Documentation/bindings/display/exynos/exynos_dp.txt
I was careful to define the bindings to be flexible enough for both cases, since the properties might be slightly different depending on the SoC.
Tested with make dt_binding_check ARCH=arm64 DT_SCHEMA_FILES=<...analogix_dp.yaml> make dtbs_check ARCH=arm64 DT_SCHEMA_FILES=<...analogix_dp.yaml>
