a8972d5a49 drm: panel: jd9365da-h3: fix reset signal polarity 
In jadard_prepare() a reset pulse is generated with the following
statements (delays ommited for clarity):

    gpiod_set_value(jadard->reset, 1); --> Deassert reset
    gpiod_set_value(jadard->reset, 0); --> Assert reset for 10ms
    gpiod_set_value(jadard->reset, 1); --> Deassert reset

However, specifying second argument of "0" to gpiod_set_value() means to
deassert the GPIO, and "1" means to assert it. If the reset signal is
defined as GPIO_ACTIVE_LOW in the DTS, the above statements will
incorrectly generate the reset pulse (inverted) and leave it asserted
(LOW) at the end of jadard_prepare().

Fix reset behavior by inverting gpiod_set_value() second argument
in jadard_prepare(). Also modify second argument to devm_gpiod_get()
in jadard_dsi_probe() to assert the reset when probing.

Do not modify it in jadard_unprepare() as it is already properly
asserted with "1", which seems to be the intended behavior.

652be03b54 drm: panel-simple: support TOPLAND TIAN G07017 LCD panel 
The TIAN-G07017-01 is a 7" TFT-LCD module by TOPLAND ELECTRONICS (H.K).
The panel features 1024x600 24-bit RGB pixels driven over LVDS as well
as a PWM backlight and I2C-connected ft5506-compatible capacitive touch.

The panel description is taken from the Datasheet V0 (2024.5.23), but
it lists no timings and these were provided by the vendor separately.

e70140ba0d Get rid of 'remove_new' relic from platform driver struct 
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

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.

2418aa8516 drm/panel: nt35510: Make new commands optional 
The commit introducing the Frida display started to write the
SETVCMOFF registers unconditionally, and some (not all!) Hydis
display seem to be affected by ghosting after the commit.

Make SETVCMOFF optional and only send these commands on the
Frida display for now.

ca097d4d94 drm/display: split DSC helpers from DP helpers 
Currently the DRM DSC functions are selected by the
DRM_DISPLAY_DP_HELPER Kconfig symbol. This is not optimal, since the DSI
code (both panel and host drivers) end up selecting the seemingly
irrelevant DP helpers. Split the DSC code to be guarded by the separate
DRM_DISPLAY_DSC_HELPER Kconfig symbol.
