* drm/panel: p079zca: unconditionally remove the panel on removalHeiko Stuebner2018-09-271-2/+1
| | | | | | | | | | | 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.

* drm/panel: p079zca: Add variable unprepare_delay propertiesLin Huang2018-07-101-2/+8
| | | | | | | | | | | | | 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.

* drm/panel: p079zca: Refactor panel driver to support multiple panelsLin Huang2018-07-101-41/+102
| | | | | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: Lin Huang <hl@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Thierry Reding <treding@nvidia.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180702102721.3546-2-heiko@sntech.de
* drm/panel: Remove drm_panel_detach() calls from all panel driversJyri Sarha2018-05-181-1/+0
| | | | | | | | | | | | | | | | | | 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.
