2024-10-31drm/panel: samsung-s6e88a0-ams427ap24: Add flip optionJakob Hauser1-0/+7
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.

2024-10-31drm/panel: samsung-s6e88a0-ams427ap24: Add brightness controlJakob Hauser2-12/+521
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.

2024-10-31drm/panel: samsung-s6e88a0-ams427ap24: Add initial driverJakob Hauser3-0/+261
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().

As discussed previously, the integrating vendor and device name are preferred instead of the OEM serial.

This reverts commit 8ebb1fc2e69ab8b89a425e402c7bd85e053b7b01. 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.

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".
