d6e8d3bc34 drm/panel: sharp: lq101r1sx01: Remove unneeded include
Nothing in the file needs symbols from include/linux/host1x.h, so remove
the include.

ee920bca27 drm/panel: sharp: lq101r1sx01: Respect power timings
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.

4569619d0f drm/panel: sharp: lq101r1sx01: Add delay after display on
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.

1976dbca04 drm/panel: Add Sharp LQ101R1SX01 support
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.
