* drm/panel: Use of_find_backlight helperMeghana Madhyastha2018-02-201-23/+5Star
| | | | | | | | | | | | Replace of_find_backlight_by_node and of the code around it with of_find_backlight helper to avoid repetition of code.

* drm/panel: Use backlight_enable/disable helpersMeghana Madhyastha2018-02-201-8/+2Star
| | | | | | | | | | | | | Use backlight_enable/disable helpers instead of changing the property and calling backlight_update_status for cleaner and simpler code and also to avoid repetitions.

| | | | | | | Nothing in the file needs symbols from include/linux/host1x.h, so remove the include. Signed-off-by: Thierry Reding <treding@nvidia.com>
* drm/panel: sharp: lq101r1sx01: Respect power timingsThierry Reding2015-01-281-9/+9
| | | | | | | | | | | | | | | Before shutting down the display using the DCS display_off command, wait for 4 frames according to the datasheet. Furthermore, after enabling the power supply, the supply voltage needs around 10 ms to settle. After that, another 120 ms is required before a DCS exit_sleep_mode command can be sent. While at it, no longer send the DCS soft_reset command. This is totally unnecessary because we've just powered up the display, hence it will be in a reset state already.

* drm/panel: sharp: lq101r1sx01: Add delay after display onThierry Reding2015-01-281-0/+13
| | | | | | | | | After switching the display on (using the DCS display_on command), wait for 6 frames (100ms at 60 Hz) to give the display more time to prepare. Failing to do this results in the panel not initializing properly in a large number of cases. Signed-off-by: Thierry Reding <treding@nvidia.com>
* drm/panel: Add Sharp LQ101R1SX01 supportThierry Reding2014-11-131-0/+464
This panel requires dual-channel mode. The device accepts command-mode data on 8 lanes and will therefore need a dual-channel DSI controller. The two interfaces that make up this device need to be instantiated in the controllers that gang up to provide the dual-channel DSI host.
