1a7a7b80a2 drm/panel: novatek-nt35560: avoid on-stack device structure
A cleanup patch apparently by accident used a local device structure
instead of a pointer to one in the nt35560_read_id() function, causing
a warning about stack usage:

drivers/gpu/drm/panel/panel-novatek-nt35560.c: In function 'nt35560_read_id':
drivers/gpu/drm/panel/panel-novatek-nt35560.c:249:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]

Change this to a pointer as was liley intended here.

94124ea5a7 drm/edp-panel: Add touchscreen panel used by Lenovo X13s
After (checks watch) a little over two years I finally investigated the
boot warning on my Thinkpad X13s and it was caused by the conservative
timings warning in panel-edp.c . The X13s was sold with a variety of
different panel versions; I have the 300 nit multi-touch variant.

I have been unable to secure panel documentation so the I copied the
timings from NV133WUM-N63.

diagonally measured active display area with WXGA resolution (800 by 1280

88148c30ef drm/panel: Add Samsung S6E3FC2X01 DDIC with AMS641RW panel
Add panel driver used in the OnePlus 6T.

No datasheet, based mostly on EDK2 init sequence and the downstream driver.

Note: This driver doesn't use previously mentioned "samsung,s6e3fc2x01"
by OnePlus 6T device-tree.
The reason is because DDIC itself without knowing the panel type used
with it will not give the driver enough information about the panel used,
as the panel cannot be autodetected.
While would be more practical to support the original compatible,
I would like to avoid it, to prevent confusing devs upstreaming DDICs.

306e6407ed gpu/drm: panel: Add Sharp LQ079L1SX01 panel support
This panel requires dual-channel mode. The device accepts video-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.

This saves some lines for error handling.

For the address mode change, that value is always an u8, so switching
to dcs_write_buffer function should be appropriate.

5efa824920 drm/panel: ilitek-ili9881c: move display_on/_off dcs calls to (un-)prepare
At least for panel-bridges, the atomic_enable call is defined as being
called right after the preceding element in the display pipe is enabled.

It is also stated that "The bridge can assume that the display pipe (i.e.
clocks and timing signals) feeding it is running when this callback is
called"

This means the DSI controller driving this display would have already
switched over to video-mode from command mode and thus dcs functions
should not be called anymore at this point.

This caused a non-working display for me, when trying to enable
the rk3576 dsi controller using a display using this controller.

Therefore move the display_on/off calls the more appropriate
prepare/unprepare callbacks.
