Subject: [PATCH v4 00/13] Apply drm_bridge_connector and panel_bridge helper for the Analogix DP driver

PATCH 1 is a small format optimization for struct analogid_dp_device.
PATCH 2 is to perform mode setting in &drm_bridge_funcs.atomic_enable.
PATCH 3-6 are preparations for apply drm_bridge_connector helper.
PATCH 7 is to apply the drm_bridge_connector helper.
PATCH 8-10 are to move the panel/bridge parsing to the Analogix side.
PATCH 11-12 are preparations for apply panel_bridge helper.
PATCH 13 is to apply the panel_bridge helper.

Damon Ding (13):
  drm/bridge: analogix_dp: Formalize the struct analogix_dp_device
  drm/bridge: analogix_dp: Move &drm_bridge_funcs.mode_set to
    &drm_bridge_funcs.atomic_enable
  drm/bridge: analogix_dp: Add &analogix_dp_plat_data.next_bridge
  drm/exynos: exynos_dp: Remove &exynos_dp_device.ptn_bridge
  drm/bridge: exynos_dp: Remove unused &exynos_dp_device.connector
  drm/bridge: analogix_dp: Remove redundant
    &analogix_dp_plat_data.skip_connector
  drm/bridge: analogix_dp: Apply drm_bridge_connector helper
  drm/bridge: analogix_dp: Add new API analogix_dp_finish_probe()
  drm/rockchip: analogix_dp: Apply analogix_dp_finish_probe()
  drm/exynos: exynos_dp: Apply analogix_dp_finish_probe()
  drm/bridge: analogix_dp: Remove panel disabling and enabling in
    analogix_dp_set_bridge()
  drm/bridge: analogix_dp: Remove bridge disabing and panel unpreparing
    in analogix_dp_unbind()
  drm/bridge: analogix_dp: Apply panel_bridge helper

Changes in v2:
- Update Exynos DP driver synchronously.
- Move the panel/bridge parsing to the Analogix side.

Changes in v3:
- Rebase for the existing devm_drm_bridge_alloc() applying commit.
- Fix the typographical error of panel/bridge check in exynos_dp_bind().
- Squash all commits related to skip_connector deletion in both Exynos and
  Analogix code into one.
- Apply panel_bridge helper to make the codes more concise.
- Fix the handing of bridge in analogix_dp_bridge_get_modes().
- Remove unnecessary parameter struct drm_connector* for callback
  &analogix_dp_plat_data.attach().
- In order to decouple the connector driver and the bridge driver, move
  the bridge connector initilization to the Rockchip and Exynos sides.

Changes in v4:
- Rebase for the applied &drm_bridge_funcs.detect() modification commit.
- Rename analogix_dp_find_panel_or_bridge() to analogix_dp_finish_probe().
- Drop the drmm_encoder_init() modification commit.
- Rename the &analogix_dp_plat_data.bridge to
  &analogix_dp_plat_data.next_bridge.
