drm: bridge: ldb: Implement simple Freescale i.MX8MP LDB bridge

2022-05-02T14:44:55+00:00

The i.MX8MP contains two syscon registers which are responsible for configuring the on-SoC DPI-to-LVDS serializer. Implement a simple bridge driver for this serializer. -- - Add sentinel of_device_table - Add RB from Sam - Rename to fsl-ldb altogether Reviewed-by: Sam Ravnborg Signed-off-by: Marek Vasut Cc: Laurent Pinchart Cc: Lucas Stach Cc: Maxime Ripard Cc: Peng Fan Cc: Robby Cai Cc: Robert Foss Cc: Sam Ravnborg Cc: Thomas Zimmermann To: dri-devel@lists.freedesktop.org V2: - Rename syscon to fsl,syscon V3: - Consistently use MX8MP V4: - Fix MODULE_DESCRIPTION to also use MX8MP Signed-off-by: Robert Foss Link: https://patchwork.freedesktop.org/patch/msgid/20220426193645.244792-2-marex@denx.de

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.

drm/bridge: Add ChromeOS EC ANX7688 bridge driver support

2021-05-18T14:41:01+00:00

This driver adds support for the ChromeOS EC ANX7688 HDMI to DP converter For our use case, the only reason the Linux kernel driver is necessary is to reject resolutions that require more bandwidth than what is available on the DP side. DP bandwidth and lane count are reported by the bridge via 2 registers and, as far as we know, only chips that have a firmware version greater than 0.85 support these two registers.

drm: bridge: Add support for Cadence MHDP8546 DPI/DP bridge

2020-09-18T12:16:01+00:00

Add a new DRM bridge driver for Cadence MHDP8546 DPTX IP used in TI J721E SoC. MHDP DPTX IP is the component that complies with VESA DisplayPort (DP) and embedded Display Port (eDP) standards. It integrates uCPU running the embedded Firmware (FW) interfaced over APB interface. Basically, it takes a DPI stream as input and outputs it encoded in DP format. Currently, it supports only SST mode.
