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.

Add support for Lontium LT9611UXC HDMI bridge. Lontium LT9611UXC is a DSI to HDMI bridge which supports two DSI ports and I2S port as an input and HDMI port as output. Despite name being similar to LT9611, these devices are different enough to warrant separate driver.

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.
