Merge branch 'drm-next-analogix-dp-v2' of github.com:yakir-Yang/linux into drm-next

This pull request want to land the analogix_dp driver into drm/bridge directory,
which reused the Exynos DP code, and add Rockchip DP support. And those
patches have been:

* 'drm-next-analogix-dp-v2' of github.com:yakir-Yang/linux:
  drm: bridge: analogix/dp: Fix the possible dead lock in bridge disable time
  drm: bridge: analogix/dp: add panel prepare/unprepare in suspend/resume time
  drm: bridge: analogix/dp: add edid modes parse in get_modes method
  drm: bridge: analogix/dp: move hpd detect to connector detect function
  drm: bridge: analogix/dp: try force hpd after plug in lookup failed
  drm: bridge: analogix/dp: add max link rate and lane count limit for RK3288
  drm: bridge: analogix/dp: add some rk3288 special registers setting
  dt-bindings: add document for rockchip variant of analogix_dp
  drm: rockchip: dp: add rockchip platform dp driver
  ARM: dts: exynos/dp: remove some properties that deprecated by analogix_dp driver
  dt-bindings: add document for analogix display port driver
  drm: bridge: analogix/dp: dynamic parse sync_pol & interlace & dynamic_range
  drm: bridge: analogix/dp: remove duplicate configuration of link rate and link count
  drm: bridge: analogix/dp: fix some obvious code style
  drm: bridge: analogix/dp: rename register constants
  drm/exynos: dp: rename implementation specific driver part
  drm: bridge: analogix/dp: split exynos dp driver to bridge directory

Device-Tree bindings for Samsung Exynos Embedded DisplayPort Transmitter(eDP)
DisplayPort is industry standard to accommodate the growing board adoption
of digital display technology within the PC and CE industries.
It consolidates the internal and external connection methods to reduce device
complexity and cost. It also supports necessary features for important cross
industry applications and provides performance scalability to enable the next
generation of displays that feature higher color depths, refresh rates, and
display resolutions.
eDP (embedded display port) device is compliant with Embedded DisplayPort
standard as follows,
- DisplayPort standard 1.1a for Exynos5250 and Exynos5260.
- DisplayPort standard 1.3 for Exynos5422s and Exynos5800.
eDP resides between FIMD and panel or FIMD and bridge such as LVDS.
The Exynos display port interface should be configured based on The Exynos display port interface should be configured based on
the type of panel connected to it. the type of panel connected to it.
