Subject: [PATCH v7 06/17] Documentation: drm/bridge: add document for analogix_dp
Analogix dp driver is split from exynos dp driver, so we just
make an copy of exynos_dp.txt, and then simplify exynos_dp.txt
Beside update some exynos dtsi file with the latest change
according to the devicetree binding documents.

Changes in v7: None
Changes in v6: None
Changes in v5: None
Changes in v4:
- Split all DTS changes, and provide backward compatibility. Mark old
properties as deprecated but still support them. (Krzysztof)
- Update "analogix,hpd-gpio" to "hpd-gpios" prop name. (Rob)
- Deprecated some properties which could parsed from Edid/Mode/DPCD. (Thierry)
"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:
- Add devicetree binding documents. (Heiko)
- Remove sync pol & colorimetry properies from the new analogix dp driver
devicetree binding. (Thierry)
- Update the exist exynos dtsi file with the latest DP DT properies.
Changes in v2: None
