drm/bridge: add support for TI TDP158
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: imx: Add i.MX8qm/qxp pixel combiner support
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.

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: Add support for Cadence MHDP8546 DPI/DP bridge
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
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.
