Signed-off-by: Yakir Yang --- Changes in v4: - Take Krzysztof suggest, split all DTS changes, and provide backward compatibility. Mark old properties as deprecated but still support them. - Take Rob suggest, update "analogix,hpd-gpio" to "hpd-gpios" prop name. - Take Thierry suggest, deprecated some properties which could parsed from Edid/Mode/DPCD. "analogix,color-space" & "analogix,color-depth" & "analogix,link-rate" & "analogix,lane-count" & "analogix,ycbcr-coeff" & "analogix,dynamic-range" & "vsync-active-high" & "hsync-active-high" & "interlaces" Changes in v3: - Take Heiko suggest, add devicetree binding documents. - Take Thierry Reding suggest, remove sync pol & colorimetry properies from the new analogix dp driver devicetree binding. - Update the exist exynos dtsi file with the latest DP DT properies.
