e70d4f8e24 drm/panel: samsung-s6e88a0-ams427ap24: Add flip option 
The way of implementing a flip option follows the existing
panel-samsung-s6e8aa0.c [1][2][3].

The value to flip the screen is taken from a downstream kernel file of
a similar but older panel [4]. The mipi clock [5] for the new panel
samsung-s6e88a0-ams427ap24 matches 461 MHz and a hardware read-out of the
0xcb values corresponds to revision R01 of that older panel [6]. Although
for samsung-s6e88a0-ams427ap24 that's in non-flipped state while in this
older driver it seems to be the other way around. Further up there is a
hint [7] basically saying for revision R01 to change the first word of the
0xcb command from 0x06 to 0x0e, which is actually setting BIT(3) of that
word. This causes a horizontal flip.

5b67fdf166 drm/panel: samsung-s6e88a0-ams427ap24: Add brightness control 
The tables for brightness to candela, aid and elvss were taken from downstream
kernel file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [1][2][3].

The gamma table gets generated in "ss_dsi_smart_dimming_S6E88A0_AMS427AP24.c" [4]
with hard-coded starting values. The function smart_dimming_init() [5] goes
through the v{*}_adjustments, generate_gray_scale and gamma_init procedure.
Instead of calculating it manually, it's easier to compile a custom downstream
kernel with SMART_DIMMING_DEBUG enabled and read out dmesg early at boot.

Selection of the values for aid and elvss are again according to downstream
file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [6][7].

The set of write commands is guided by downstream file "ss_dsi_panel_common.c" [8]
followed by "ss_dsi_panel_S6E88A0_AMS427AP24.c" [9].

The dsi mode flag MIPI_DSI_MODE_VIDEO_NO_HFP prevents screen flickering while
changing the brightness.

d5658db2a0 drm/panel: samsung-s6e88a0-ams427ap24: Add initial driver 
This initial part of the panel driver was mostly generated by the
"linux-mdss-dsi-panel-driver-generator" tool [1], reading downstream
Android kernel file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [2].

On top of the generic output of the tool, there were a couple of changes
applied:
- Added mipi_dsi_dcs_set_display_on() to function s6e88a0_ams427ap24_on(),
  otherwise the display does not show up.
- In functions s6e88a0_ams427ap24_on() and s6e88a0_ams427ap24_off()
  changed DSI commands to multi context and used "accum_err" returns.
- In functions s6e88a0_ams427ap24_on() and s6e88a0_ams427ap24_off() replaced
  msleep() by mipi_dsi_msleep().
- The function s6e88a0_ams427ap24_get_modes() was changed to make use of
  drm_connector_helper_get_modes_fixed(). This also required to include
  drm/drm_probe_helper.h.
- In function s6e88a0_ams427ap24_probe() registring the regulators was changed
  to devm_regulator_bulk_get_const(). This required to change supplies in struct
  s6e88a0_ams427ap24 to a pointer.
- Removed bool "prepared" from struct s6e88a0_ams427ap24 and according parts in
  functions s6e88a0_ams427ap24_prepare() and s6e88a0_ams427ap24_unprepare().
- Removed include <linux/of.h>, it's not needed.
- Added comments to the mipi_dsi_dcs_write_seq_multi() lines in function
  s6e88a0_ams427ap24_on().

The Anbernic RG35XX devices use an SPI LCD panel from an unknown OEM,
with an NV3052C driver chip.

As discussed previously, the integrating vendor and device name are
preferred instead of the OEM serial. A previous patch corrected the
device tree binding and of_device_id in the NV3052C driver, however the
spi_device_id also needs correction.

Correct the spi_device_id for the RG35XX panel.

01cc7b2e8a Revert "drm/panel-edp: Add SDC ATNA45AF01" 
This reverts commit 8ebb1fc2e6.

The panel should be handled through the samsung-atna33xc20 driver for
correct power up timings. Otherwise the backlight does not work correctly.

We have existing users of this panel through the generic "edp-panel"
compatible (e.g. the Qualcomm X1E80100 CRD), but the screen works only
partially in that configuration: It works after boot but once the screen
gets disabled it does not turn on again until after reboot. It behaves the
same way with the default "conservative" timings, so we might as well drop
the configuration from the panel-edp driver. That way, users with old DTBs
will get a warning and can move to the new driver.

97d1f449c3 drm/panel: jd9365da: Move "exit sleep mode" and "set display on" cmds 
Move the "exit sleep mode" and "set display on" command from
enable() to init() function.

As mentioned in the patch:
https://lore.kernel.org/all/20240624141926.5250-2-lvzhaoxiong@huaqin.corp-partner.google.com/

The Mediatek Soc DSI host has different modes in prepare() and
enable() functions, prepare() is in LP mode and enable() is in
HS mode. Since the "exit sleep mode" and "set display on"
command must also be sent in LP mode, so we also move "exit
sleep mode" and "set display on" command to the init() function.

We have no other actions in the enable() function after moves
"exit sleep mode" and "set display on", and we checked the call
of the enable() function during the "startup" process. It seems
that only one judgment was made in drm_panel_enabel(). If the
panel does not define enable(), the judgment will skip the
enable() and continue execution. This does not seem to have
any other effect, and we found that some drivers also seem
to have no enable() function added, for example:
panel-asus-z00t-tm5p5-n35596 / panel-boe-himax8279d...
In addition, we briefly tested the kingdisplay_kd101ne3 panel and
melfas_lmfbx101117480 panel, and it seems that there is no garbage
on the panel, so we delete enable() function.

After moving the "exit sleep mode" and "set display on" command
to the init() function, we no longer need additional delay
judgment, so we delete variables "exit_sleep_to_display_on_delay_ms"
and "display_on_delay_ms".

f7c4a15225 drm/panel: st7701: Add Anbernic RG28XX panel support 
The Anbernic RG28XX is a handheld gaming device with a 2.8 inch 480x640
display. Add support for the display panel.

This panel is driven by a variant of ST7701 driver IC internally,
confirmed by dumping and analyzing its BSP initialization sequence
by using a logic analyzer. It is very similar to the existing
densitron,dmt028vghmcmi-1a panel, but differs in some unknown
register values. Besides, it is connected via SPI, so add a new entry
for the panel.
