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.

drm/bridge: tc358762: Add basic driver for Toshiba TC358762 DSI-to-DPI bridge

2020-08-12T20:06:18+00:00

Add very basic driver for Toshiba TC358762 DSI-to-DPI bridge, derived from tc358764 driver and panel-raspberrypi-touchscreen. This driver is meant to replace the panel-raspberrypi-touchscreen too, as the bridge connection can be described in DT too.

drm/bridge: chrontel-ch7033: Add a new driver

2020-05-05T07:48:56+00:00

This is a driver for video encoder with VGA and DVI/HDMI outputs. There is no documentation for the chip -- the operation was guessed from what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names come from the ch7035 driver in Mediatek's GPL code dump. Only bare minimum is implemented -- no fancy stuff, such as scaling. That would only worsen our misery. We don't load the firmware and we don't need to even bother enabling the MCU. There are probably no distributable firmware images anyway. Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60, with VGA as well as DVI.

drm/bridge: Add NWL MIPI DSI host controller support

2020-04-09T13:52:47+00:00

This adds initial support for the NWL MIPI DSI Host controller found on i.MX8 SoCs. It adds support for the i.MX8MQ but the same IP can be found on e.g. the i.MX8QXP. It has been tested on the Librem 5 devkit using mxsfb.

drm/bridge: Add bridge driver for display connectors

2020-02-26T11:31:37+00:00

Display connectors are modelled in DT as a device node, but have so far been handled manually in several bridge drivers. This resulted in duplicate code in several bridge drivers, with slightly different (and thus confusing) logics. In order to fix this, implement a bridge driver for display connectors. The driver centralises logic for the DVI, HDMI, VGAn composite and S-video connectors and exposes corresponding bridge operations. This driver in itself doesn't solve the issue completely, changes in bridge and display controller drivers are needed to make use of the new connector driver.
