Failing to read the MTP over DSI should not bring down the

out that this happens when toggling the display off and on,
and that write is often still working so the display output
is just fine. Printing an error is enough.

A recent patch renaming MIPI_DSI_MODE_EOT_PACKET to
MIPI_DSI_MODE_NO_EOT_PACKET brought to light the
misunderstanding in the current MCDE driver and all
its associated panel drivers that MIPI_DSI_MODE_EOT_PACKET
would mean "use EOT packet" when in fact it means the
reverse.
Fix it up by implementing the flag right in the MCDE
DSI driver and remove the flag from panels that actually
want the EOT packet.

drm/panel: sony-acx565akm: Fix race condition in probe
...
The probe routine acquires the reset GPIO using GPIOD_OUT_LOW. Directly
afterwards it calls acx565akm_detect(), which sets the GPIO value to
HIGH. If the bootloader initialized the GPIO to HIGH before the probe
routine was called, there is only a very short time period of a few
instructions where the reset signal is LOW. Exact time depends on
compiler optimizations, kernel configuration and alignment of the stars,
but I expect it to be always way less than 10us. There are no public
datasheets for the panel, but acx565akm_power_on() has a comment with
timings and reset period should be at least 10us. So this potentially
brings the panel into a half-reset state.
The result is, that panel may not work after boot and can get into a
working state by re-enabling it (e.g. by blanking + unblanking), since
that does a clean reset cycle. This bug has recently been hit by Ivaylo
Dimitrov, but there are some older reports which are probably the same
bug. At least Tony Lindgren, Peter Ujfalusi and Jarkko Nikula have
experienced it in 2017 describing the blank/unblank procedure as
possible workaround.
Note, that the bug really goes back in time. It has originally been
introduced in the predecessor of the omapfb driver in commit 3c45d05be384192742d945f16c82dbjarkko.nikula@bitmer.com >

drm/panel: s6e63m0: Order enable/disable sequence
...
The upstream S6E63M0 driver has some peculiarities around
the prepare/enable disable/unprepare sequence: the screen
is taken out of sleep in prepare() as part of
s6e63m0_init() the put to on with MIPI_DCS_SET_DISPLAY_ON
in enable().
However it is just put into sleep mode directly in
disable(). As disable()/enable() can be called without
unprepare()/prepare() being called, this is unbalanced,
we should take the display out of sleep in enable()
then turn it off().
Further MIPI_DCS_SET_DISPLAY_OFF is never called
balanced with MIPI_DCS_SET_DISPLAY_ON.
The vendor driver for Samsung GT-I8190 (Golden) does all
of these things in strict order.
Augment the driver to do exit sleep/set display on in
enable() and set display off/enter sleep in disable().
Further send an explicit reset pulse in power_on() so we
come up in a known state, and issue the MCS_ERROR_CHECK
command after setting display on like the vendor driver
does. Also use the timings from the vendor driver in
the sequence.
Doing all of these things makes the display much more
stable on the Samsung GT-I8190 when enabling/disabling
the display pipeline.

drm/panel: s6e63m0: Break out SPI transport
...
This panel can be accessed using both SPI and DSI.
To make it possible to probe and use the device also from
a DSI bus, first break out the SPI support to its own file.
Since all the panel driver does is write DCS commands to
the panel, we pass a DCS write function to probe()
from each subdriver.
We make the Kconfig entry for SPI mode default so all
current users will continue to work.
