2022-06-20drm/bridge: imx: Add i.MX8qm/qxp pixel combiner supportLiu Ying1-0/+2
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.

2022-04-19drm/bridge: lt9211: Add Lontium LT9211 bridge driverMarek Vasut1-0/+13
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.

To make debugging easier, convert driver to regmap. Implement read and write regmap tables for known registers, keep all known register readable and mark those which are obviously read-only as not writeable. Use common I2C regmap for the I2C configuration, implement custom regmap bus for DSI configuration. The later is mandatory as this chip requires one extra byte set to read access length between register address and data.

2022-03-31drm/bridge: tc358767: Add DSI-to-DPI mode supportMarek Vasut1-0/+1
The TC358767/TC358867/TC9595 are all capable of operating in multiple modes, DPI-to-(e)DP, DSI-to-(e)DP, DSI-to-DPI. Add support for the DSI-to-DPI mode. This requires skipping most of the (e)DP initialization code, which is currently a large part of this driver, hence it is better to have far simpler separate tc_dpi_bridge_funcs and their implementation. The configuration of DPI output is also much simpler. The configuration of the DSI input is rather similar to the other TC bridge chips. The Pixel PLL in DPI output mode does not have the 65..150 MHz limitation imposed on the (e)DP output mode, so this limitation is skipped to permit operating panels with far slower pixel clock, even below 9 MHz. This mode of operation of the PLL is valid and tested. The detection of bridge mode is now added into tc_probe_bridge_mode(), where in case a DPI panel is found on port@1 endpoint@1, the mode is assumed to be DSI-to-DPI. If (e)DP is detected on port@2, the mode is assumed to be DPI-to-(e)DP. The DSI-to-(e)DP mode is not supported due to lack of proper hardware, but this would be some sort of mix between the two aforementioned modes.

Conventionally, panel is listed under the root of the device tree. When userland asks for display mode, ps8640 bridge is responsible for returning EDID when ps8640_bridge_get_edid() is called. Now enable a new option of listing panel under "aux-bus" of ps8640 bridge node in the device tree. In this case, panel driver can retrieve EDID by triggering AUX transactions, without ps8640_bridge_get_edid() calls at all.

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.

2021-05-03drm/bridge: ti-sn65dsi86: Break GPIO and MIPI-to-eDP bridge into sub-driversDouglas Anderson1-0/+1
Let's use the newly minted aux bus to break up the driver into sub drivers. We're not doing a full breakup here: all the code is still in the same file and remains largely untouched. The big goal here of using sub-drivers is to allow part of our code to finish probing even if some other code needs to defer. This can solve some chicken-and-egg problems. Specifically: - In commit 48834e6084f1 ("drm/panel-simple: Support hpd-gpios for delaying prepare()") we had to add a bit of a hack to simpel-panel to support HPD showing up late. We can get rid of that hack now since the GPIO part of our driver can finish probing early. - We have a desire to expose our DDC bus to simple-panel (and perhaps to a backlight driver?). That will end up with the same chicken-and-egg problem. A future patch to move this to a sub-driver will fix it. - If/when we support the PWM functionality present in the bridge chip for a backlight we'll end up with another chicken-and-egg problem. If we allow the PWM to be a sub-driver too then it solves this problem.

2020-06-13treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada1-8/+8
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-05-05drm/bridge: chrontel-ch7033: Add a new driverLubomir Rintel1-0/+10
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.

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.

2020-02-26drm/bridge: Add bridge driver for display connectorsLaurent Pinchart1-0/+11
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.
