882c35af56 drm/panel: p079zca: unconditionally remove the panel on removal
There is no need to check innolux->base.dev when trying to remove
the panel, as that variable is always set directly before the panel
gets added and will still be available on panel_remove.

48bd379aa2 drm/panel: p079zca: Add variable unprepare_delay properties
When panel power down, p079zca need delay between reset and disable
power supply, but p097pfg does not need it. Similarly p097zca needs
a delay after entering panel sleep mode. So add two delay properties,
so we can meet these two panel power down sequence.

7ad4e4636c drm/panel: p079zca: Refactor panel driver to support multiple panels
Refactor Innolux P079ZCA panel driver, let it support multi panels from
Innolux that share similar power sequences.

Panels may require different power supplies so use regulator bulk
interfaces and define per panel supply-names.

Changes in v2:
- Change regulator property name to meet the panel datasheet
Changes in v3:
- this patch only refactor P079ZCA panel to support multi panel,
  support P097PFG panel in another patch
Changes in v4:
- Modify the patch which suggest by Thierry
Changes in v5:
- use regulator_bulk to handle different supply number

38992c57c9 drm/panel: Remove drm_panel_detach() calls from all panel drivers
Remove all drm_panel_detach() calls from all panel drivers and update
the kerneldoc for drm_panel_detach().

Setting the connector and drm to NULL when the DRM panel device is going
away hardly serves any purpose. Usually the whole memory structure is
freed right after the remove call. However, calling the detach function
from the master DRM device, and setting the connector pointer to NULL,
has the logic of marking the panel again as available for another DRM
master to attach. The usual situation would be the same DRM master
device binding again.
