2026-10-02drivers: gpu: drm: panel: Add BOE NT51021 driverNickolay Goppen
Add driver for BOE NT51021-based 8-inch and 10-inch DSI video mode panels used in Xiaomi Mi Pad 4, Mi Pad 4 Plus (xiaomi-clover) and Amazon Fire HD 10 (2017) (amazon-suez) tablets. NT51021-based panels also support content-adaptive brightness control by generating a PWM signal for backlight driver IC. Content adaptation means that content grey level scale can be increased while simultaneously decreasing brightness of the backlight to achieve same perceived brightness. This makes the power consumption of backlight be reduced with keeping acceptable display quality. Both panels are very similar, differences are only in init sequence and resolution. The register sequence of the TV101WUM-NM0 is the BOE branch of init_lcm_registers() in drivers/misc/mediatek/lcm/nt51021_wuxga_dsi_vdo/ in the Fire OS 3.18 tree, command for command, with only a 120 ms wait after sleep-out added where the vendor waits its trailing 5 ms. The 0x8f 0xa5 and 0x8f 0x00 that bracket it are the vendor's command interface selection, sent on every board that is not an early proto or HVT unit. It is much shorter than boe_tv101wum_nx0_init() because this module is left on its own factory trim. NT51021 R8CH selects whether V1/V14, gamma and HAOP come from the panel's OTP memory or from control registers, and the 0x8c 0x80 here leaves all three on OTP, where the NX0's 0x8e switches them to registers so that the three pages of gamma it then writes take effect. So the absent gamma is deliberate rather than an omission, and the differing 0x8c is its consequence. CABC is likewise untouched because the vendor drives it over I2C from the backlight path. What is left is 0xc0 and 0xc8, which the public NT51021 specification does not describe; everything else this sequence touches carries the same value as the other two panels, including the terminal resistor, TP_SYNC, the MIPI Rx drive strength and all three test modes. The timings are the vendor's lcm_get_params(): hsync 1, hbp 32, hfp 110, vsync 1, vbp 14, vfp 11, so htotal 1343 and vtotal 1946. The pixel clock follows the vendor's PLL_CLOCK = 490, which after DDR is 980 Mbps per lane and over four lanes at 24bpp is 163.33 MHz, so 62.5 Hz. The bootloader leaves the MIPI TX PLL at that rate: read back before the kernel touches it, this board's PLL decodes to exactly 980 Mbps per lane, so the panel is already there when the kernel takes over. The front porch is the vendor's declared 110 rather than the smaller value its own DSI driver ends up running. That driver also sets clk_lp_per_line_enable, which makes ddp_dsi_config() overwrite HFP_WC after the declared timing is programmed, shrinking it to leave just enough room to take the clock lane to LP and back. That is a controller-side workaround rather than a panel property, and it contradicts the cont_clock = 1 set beside it, which disables the very LP transition it makes room for. Mainline mtk_dsi handles the clock lane itself, so the panel's declared timing is the right thing to carry here. The vendor asks for SYNC_EVENT_VDO_MODE with cont_clock = 1 rather than burst, so make mode_flags per variant instead of fixed in probe(). The two existing panels keep the flags they had. Burst was also tried on this hardware and worked, but the vendor configuration is the one the module is characterised for. The physical size is the datasheet active area, 216.576 x 135.36 mm, which measures 216 x 135 on the glass. The vendor's declared a physical_width = 136 and physical_height = 221, which appears to be an error. The size of the test unit was physically measured. 1200/136 and 1920/221 disagree by 1.5%. The vendor's bootloader and kernel both carry a second register sequence for the Innolux module this board second-sources against, selected from two board ID straps. No Innolux unit was available, so that sequence is left out rather than carried untested; however, the Innolux part number was identified as "P101KDA-AB0", should someone with that glass need to upstream support in the future. Tested on the Amazon Fire HD 10 (2017) driven by mediatek-drm: 1200x1920 at 62.5 Hz across a cold boot, display off and on cycles and a suspend/resume, with the MIPI TX PLL reading back at the intended rate every time.

2026-10-01drm/panel: select DRM_KMS_HELPERSasha Levin
Since the panel_bridge code moved into drm_panel.c, any config with DRM built in but without the KMS helpers fails to link, for example arc haps_hs_smp_defconfig with allnoconfig and the kselftest fragment: arc-elf32-ld: drivers/gpu/drm/drm_panel.o:(.rodata+0x28): undefined reference to `drm_atomic_helper_bridge_duplicate_state' arc-elf32-ld: drivers/gpu/drm/drm_panel.o:(.rodata+0x2c): undefined reference to `drm_atomic_helper_bridge_destroy_state' ... With DRM=m, modpost fails the same way: ERROR: modpost: drivers/gpu/drm/drm_panel.ko: symbol 'drm_atomic_helper_bridge_duplicate_state' undefined! The panel_bridge used to live in bridge/panel.c, which was part of drm_kms_helper and was therefore only built when DRM_KMS_HELPER was enabled. drm_panel.c is built for DRM_PANEL instead, which DRM_PANEL_BRIDGE selects whenever DRM_BRIDGE is set, and DRM_BRIDGE is enabled for every DRM config. Nothing on that path selects DRM_KMS_HELPER, so the bridge and connector helpers used by the moved code can be missing. The panel_bridge code in drm_panel.c is built unconditionally, so make DRM_PANEL select DRM_KMS_HELPER.

2026-09-28drm/panel: move to a new moduleLuca Ceresoli
Work is in progress for every drm_panel to embed a drm_bridge, which will make the drm_panel code (currently in the drm module) depend on the drm_kms_helper module. To avoid the main drm module to depend on other drm modules and create a depepdency loop, move drm_panel.o to a new drm_panel module, so the module dependency will be drm_panel -> drm_kms_helper instead.

Add support for the Rocktech RK050HR345-CT106A panel based on the Ilitek ILI9806E controller using the SPI bus. The driver is designed to be easily extensible to support other panels with different initialization sequences and display timings by providing a specific descriptor structure for each model.

Split the driver to support multiple transport buses. The core logic (power, GPIO, backlight) is moved to a dedicated core module, while DSI-specific code is restricted to the DSI module. Introduce DRM_PANEL_ILITEK_ILI9806E_CORE as a hidden Kconfig symbol selected by the bus-specific configuration.

2026-03-26drm/panel: ilitek-ili9806e: rename to specific DSI driverDario Binacchi
The Ilitek ILI9806E controller can support different transport buses, such as MIPI-DSI and SPI. The current implementation is specific to the MIPI-DSI interface. In preparation for adding SPI support, rename the current Kconfig symbol and files to be DSI-specific, clarifying the current scope of the code. Since DRM_PANEL_ILITEK_ILI9806E is not used in any in-tree defconfig, the symbol is renamed directly to DRM_PANEL_ILITEK_ILI9806E_DSI without providing a legacy compatibility alias.

2025-10-29drm/panel: Add Samsung S6E3FC2X01 DDIC with AMS641RW panelDavid Heidelberg
Add panel driver used in the OnePlus 6T. No datasheet, based mostly on EDK2 init sequence and the downstream driver. Note: This driver doesn't use previously mentioned "samsung,s6e3fc2x01" by OnePlus 6T device-tree. The reason is because DDIC itself without knowing the panel type used with it will not give the driver enough information about the panel used, as the panel cannot be autodetected. While would be more practical to support the original compatible, I would like to avoid it, to prevent confusing devs upstreaming DDICs.
