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.

Add basic support for the Toshiba TC358768 RGB to DSI bridge. Not all the features of the TC358768 is implemented by the initial driver: MIPI_DSI_MODE_VIDEO and MIPI_DSI_FMT_RGB888 is only supported and tested. Only write is implemented for mipi_dsi_host_ops.transfer.

drm/bridge: Repurpose lvds-encoder.c

2019-12-18T11:26:07+00:00

lvds-encoder.c implementation is also suitable for LVDS decoders, not just LVDS encoders. Instead of creating a new driver for addressing support for transparent LVDS decoders, repurpose lvds-encoder.c for the greater good with this patch. This patch only "rebrands" the lvds-encoder.c driver, to make it suitable for hosting LVDS decoders support. The actual support for LVDS decoders will come with a later patch.
