drm: bridge: Add waveshare DSI2DPI unit driver

2025-08-06T06:49:33+00:00

Waveshare touchscreen consists of a DPI panel and a driver board. The waveshare driver board consists of ICN6211 and a MCU to convert DSI to DPI and control the backlight. This driver treats the MCU and ICN6211 board as a whole unit. It can support all resolution waveshare DSI2DPI based panel, the timing table should come from 'panel-dpi' panel in the device tree.

drm: bridge: Add support for Solomon SSD2825 RGB/DSI bridge

2025-07-30T21:21:31+00:00

SSD2825 is a cost-effective MIPI Bridge Chip solution targeting mainly smartphones. It can convert 24bit RGB interface into 4-lane MIPI-DSI interface to drive display modules of up to 800 x 1366, while supporting AMOLED, a-si LCD or LTPS panel technologies for smartphone applications.

drm/i2c: move TDA998x driver under drivers/gpu/drm/bridge

2025-02-12T22:19:41+00:00

TDA998x is the HDMI bridge driver, incorporating drm_connector and optional drm_encoder (created via the component bind API by the TICLDC and HDLCD drivers). Thus it should be residing together with the other DRM bridge drivers under drivers/gpu/drm/bridge/.

drm/bridge: Add ITE IT6263 LVDS to HDMI converter

2024-11-05T11:26:43+00:00

Add basic HDMI video output support. Currently, only RGB888 output pixel format is supported. At the LVDS input side, the driver supports single LVDS link and dual LVDS links with "jeida-24" LVDS mapping.

drm/bridge: add support for TI TDP158

2024-09-03T12:34:16+00:00

TDP158 is an AC-coupled DVI / HDMI to TMDS level shifting Redriver. It supports DVI 1.0, HDMI 1.4b and 2.0b. It supports 4 TMDS channels, HPD, and a DDC interface. It supports dual power supply rails (1.1V on VDD, 3.3V on VCC) for power reduction. Several methods of power management are implemented to reduce overall power consumption. It supports fixed receiver EQ gain using I2C or pin strap to compensate for different lengths input cable or board traces. Features - AC-coupled TMDS or DisplayPort dual-mode physical layer input to HDMI 2.0b TMDS physical layer output supporting up to 6Gbps data rate, compatible with HDMI 2.0b electrical parameters - DisplayPort dual-mode standard version 1.1 - Programmable fixed receiver equalizer up to 15.5dB - Global or independent high speed lane control, pre-emphasis and transmit swing, and slew rate control - I2C or pin strap programmable - Configurable as a DisplayPort redriver through I2C - Full lane swap on main lanes - Low power consumption (200 mW at 6Gbps, 8 mW in shutdown) https://www.ti.com/lit/ds/symlink/tdp158.pdf On our board, I2C_EN is pulled high. Thus, this code defines a module_i2c_driver. The default settings work fine for our use-case. So this basic driver doesn't need to tweak any I2C registers.

drm/bridge: add transparent bridge helper

2023-12-04T14:07:29+00:00

Define a helper for creating simple transparent bridges which serve the only purpose of linking devices into the bridge chain up to the last bridge representing the connector. This is especially useful for DP/USB-C bridge chains, which can span across several devices, but do not require any additional functionality from the intermediate bridges.

drm: bridge: Generalize Exynos-DSI driver into a Samsung DSIM bridge

2023-03-28T00:05:41+00:00

Samsung MIPI DSIM controller is common DSI IP that can be used in various SoCs like Exynos, i.MX8M Mini/Nano. In order to access this DSI controller between various platform SoCs, the ideal way to incorporate this in the drm stack is via the drm bridge driver. We already have a consolidated code for supporting component and bridge based DRM drivers, so keep the exynos component based code in existing exynos_drm_dsi.c and move generic bridge code as part of samsung-dsim.c Tested-by: Marek Szyprowski Reviewed-by: Marek Vasut Signed-off-by: Marek Szyprowski Signed-off-by: Jagan Teki Signed-off-by: Inki Dae
