drm/bridge: implement generic DP HPD bridge

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

Several USB-C controllers implement a pretty simple DRM bridge which implements just the HPD notification operations. Add special helper for creating such simple bridges.

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

drm/bridge: imx: Add i.MX8qm/qxp pixel combiner support

2022-06-20T19:15:07+00:00

This patch adds a drm bridge driver for i.MX8qm/qxp pixel combiner. The pixel combiner takes two output streams from a single display controller and manipulates the two streams to support a number of modes(bypass, pixel combine, YUV444 to YUV422, split_RGB) configured as either one screen, two screens, or virtual screens. The pixel combiner is also responsible for generating some of the control signals for the pixel link output channel. For now, the driver only supports the bypass mode.

drm: bridge: Add TI DLPC3433 DSI to DMD bridge

2022-06-03T14:23:31+00:00

TI DLPC3433 is a MIPI DSI based display controller bridge for processing high resolution DMD based projectors. It has a flexible configuration of MIPI DSI and DPI signal input that produces a DMD output in RGB565, RGB666, RGB888 formats. It supports upto 720p resolution with 60 and 120 Hz refresh rates. Add bridge driver for it.

drm/bridge: lt9211: Add Lontium LT9211 bridge driver

2022-04-19T14:47:38+00:00

Add driver for Lontium LT9211 Single/Dual-Link DSI/LVDS or Single DPI to Single-link/Dual-Link DSI/LVDS or Single DPI bridge. This chip is highly capable at converting formats, but sadly it is also highly undocumented. This driver is written without any documentation from Lontium and based only on shreds of information available in various obscure example codes, hence long runs of unknown register patches and lengthy delays in various places. Whichever register meaning could be divined from its behavior has at least a comment around it. Currently the only mode tested is Single-link DSI to Single-link LVDS. Dual-link LVDS might work as well, the register programming is in place, but is untested.

drm/bridge: ti-sn65dsi83: Add TI SN65DSI83 and SN65DSI84 driver

2021-06-08T09:42:25+00:00

Add driver for TI SN65DSI83 Single-link DSI to Single-link LVDS bridge and TI SN65DSI84 Single-link DSI to Dual-link or 2x Single-link LVDS bridge. TI SN65DSI85 is unsupported due to lack of hardware to test on, but easy to add. The driver operates the chip via I2C bus. Currently the LVDS clock are always derived from DSI clock lane, which is the usual mode of operation. Support for clock from external oscillator is not implemented, but it is easy to add if ever needed. Only RGB888 pixel format is implemented, the LVDS666 is not supported, but could be added if needed.
