Initial driver for S6D7AA0-controlled panels. Currently, the following
panels are supported:
- S6D7AA0-LSL080AL02 (Samsung Galaxy Tab 3 8.0)
- S6D7AA0-LSL080AL03 (Samsung Galaxy Tab A 8.0 2015)
- S6D7AA0-LTL101AT01 (Samsung Galaxy Tab A 9.7 2015)
It should be possible to extend this driver to work with other panels
using this IC.

Add support for the Sony TD4353 JDI 2160x1080 display panel used in
some Sony Xperia XZ2 and XZ2 Compact smartphones. Due to the specifics
of smartphone manufacturing, it is impossible to retrieve a better name
for this panel.
This revision adds support for the default 60 Hz configuration, however
there could possibly be some room for expansion, as the display panels
used on Sony devices have historically been capable of >2x refresh rate
overclocking.

The panel-simple driver handles way too much. Let's start trying to
get a handle on it by splitting out the eDP panels. This patch does
this:
1. Start by copying simple-panel verbatim over to a new driver,
simple-panel-edp.
2. Rename "panel_simple" to "panel_edp" in the new driver.
3. Keep only panels marked with `DRM_MODE_CONNECTOR_eDP` in the new
driver. Remove those panels from the old driver.
4. Remove all recent "DP AUX bus" stuff from the old driver. The DP
AUX bus is only possible on DP panels.
5. Remove all DSI / MIPI related functions from the new driver.
6. Remove bus_format / bus_flags from eDP driver. These things don't
seem to make any sense for eDP panels so let's stop filling in made
up stuff.
In the end we end up with a bunch of duplicated code for now. Future
patches will try to address _some_ of this duplicated code though some
of it will be unavoidable.
NOTE: This may not actually move all eDP panels over to the new driver
since not all panels were properly marked with
`DRM_MODE_CONNECTOR_eDP`. A future patch will attempt to move wayward
panels I could identify but even so there may be some missed.

The Samsung ATNA33XC20 panel is an AMOLED eDP panel that has backlight
control over the DP AUX channel.
This panel is _almost_ able to be controlled in a "simple" way (and it
originally was implemented in panel-simple.c), but it's really
impossible to get the backlight semantics right there without adding
wacky special-case code to panel-simple. Let's give up and clone the
parts of panel-simple that we need and implement the power sequence
that this panel needs.
NOTE: we'll still leave the devicetree bindings alone. Even though the
power-sequencing is non-standard the bindings are still "simple".

Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI
panel.
V11:
- Use the backlight support in drm_panel to simplify the driver (Sam)
V10:
- Adjust init code, make the format more concise (Emil)
V9:
- kill off default_off_cmds (Emil)
- use mipi_dsi_dcs_set_display_{on,off} in their enable/disable
callbacks. (Emil)
- Adjusting the delay function (Emil)
V8:
- modify PARENTHESIS_ALIGNMENT format (Sam)
- use gpios are required API replace optional gpio API (Emil)
V7:
- Modify communication address
V6:
- Add the information of the reviewer
- Remove unnecessary delays, The udelay_range code gracefully returns
without hitting the scheduler on a delay of 0. (Derek)
- Merge the same data structures, like display_mode and off_cmds (Derek)
- Optimize the processing of results returned by
devm_gpiod_get_optional (Derek)
V5:
- Add the information of the reviewer (Sam)
- Delete unnecessary header files #include <linux/fb.h> (Sam)
- The config DRM_PANEL_BOE_HIMAX8279D appears twice. Drop one of them (Sam)
- ADD static, set_gpios function is not used outside this module (Sam)
V4:
- Frefix all function maes with boe_ (Sam)
- Fsed "enable_gpio" replace "reset_gpio", Make it look clearer (Sam)
- Sort include lines alphabetically (Sam)
- Fixed entries in the makefile must be sorted alphabetically (Sam)
- Add send_mipi_cmds function to avoid duplicating the code (Sam)
- Add the necessary delay(reset_delay_t5) between reset and sending
the initialization command (Rock wang)
V3:
- Remove unnecessary delays in sending initialization commands (Jitao Shi)
V2:
- Use SPDX identifier (Sam)
- Use necessary header files replace drmP.h (Sam)
- Delete unnecessary header files #include <linux/err.h> (Sam)
- Specifies a GPIOs array to control the reset timing,
instead of reading "dsi-reset-sequence" data from DTS (Sam)
- Delete backlight_disable() function when already disabled (Sam)
- Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam)
- Move the necessary data in the DTS to the current file,
like porch, display_mode and Init code etc. (Sam)
- Add compatible device "boe,himax8279d10p" (Sam)
V1:
- Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI
panel.

This panel is used on the OMAP3 Pandora.
The code is based on the omapdrm-specific panel-tpo-td043mtea1 driver.
v2:
- fix checkpatch warnings
o (lcd == NULL) => (!lcd) (sam)
o alignment to open '(' (sam)
