Removes mipi_dsi_dcs_set_tear_off and replaces it with a multi version as after replacing it in sony-td4353-jdi, it doesn't appear anywhere else. sony-td4353-jdi is converted to use multi style functions, including mipi_dsi_dcs_set_tear_off_multi.

2025-02-20drm/panel: ilitek-ili9882t: fix GPIO name in error messageJohn Keeping
This driver uses the enable-gpios property and it is confusing that the error message refers to reset-gpios. Use the correct name when the enable GPIO is not found.

2025-02-13drm: panel: jd9365da-h3: fix reset signal polarityHugo Villeneuve
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.

2025-02-11drm/edp-panel: Add panel used by T14s Gen6 SnapdragonSebastian Reichel
The Lenovo Thinkpad T14s Gen6 Snapdragon is currently sold with three different panel versions: OLED, Low Power IPS or IPS with Touchscreen. My Low Power IPS version had this panel and the kernel complained about not knowing any details. I don't have any panel documentation, but as far as I can see the same timings for the already supported CSO panel also work for this one.

2025-01-13drm/panel-edp: Add Starry 116KHD024006Douglas Anderson
We have a few reports of sc7180-trogdor-pompom devices that have a panel in them that IDs as STA 0x0004 and has the following raw EDID: 00 ff ff ff ff ff ff 00 4e 81 04 00 00 00 00 00 10 20 01 04 a5 1a 0e 78 0a dc dd 96 5b 5b 91 28 1f 52 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 8e 1c 56 a0 50 00 1e 30 28 20 55 00 00 90 10 00 00 18 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 fe 00 31 31 36 4b 48 44 30 32 34 30 30 36 0a 00 e6 We've been unable to locate a datasheet for this panel and our partner has not been responsive, but all Starry eDP datasheets that we can find agree on the same timing (delay_100_500_e200) so it should be safe to use that here instead of the super conservative timings. We'll still go a little extra conservative and allow `hpd_absent` of 200 instead of 100 because that won't add any real-world delay in most cases. We'll associate the string from the EDID ("116KHD024006") with this panel. Given that the ID is the suspicious value of 0x0004 it seems likely that Starry doesn't always update their IDs but the string will still work to differentiate if we ever need to in the future.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2024-10-31drm/panel: samsung-s6e88a0-ams427ap24: Add flip optionJakob Hauser
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 Hauser
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 Hauser
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().

2024-10-20drm: panel: nv3052c: correct spi_device_id for RG35XX panelRyan Walklin
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.
