drm/panel: Add support for Sharp LS060T1SX01 panel

2021-10-10T17:14:43+00:00

Add driver to support Sharp LS06T1SX01 FullHD panel. The panel uses nt35695 driver IC. For example this LCD module can be found in the kwaek.ca Dragonboard Display Adapter Bundle.

drm/panel-edp: Split eDP panels out of panel-simple

2021-09-20T16:22:05+00:00

The panel-simple driver handles way too much. Let's start trying to get a handle on it by splitting out the eDP panels. This patch does this: 1. Start by copying simple-panel verbatim over to a new driver, simple-panel-edp. 2. Rename "panel_simple" to "panel_edp" in the new driver. 3. Keep only panels marked with `DRM_MODE_CONNECTOR_eDP` in the new driver. Remove those panels from the old driver. 4. Remove all recent "DP AUX bus" stuff from the old driver. The DP AUX bus is only possible on DP panels. 5. Remove all DSI / MIPI related functions from the new driver. 6. Remove bus_format / bus_flags from eDP driver. These things don't seem to make any sense for eDP panels so let's stop filling in made up stuff. In the end we end up with a bunch of duplicated code for now. Future patches will try to address _some_ of this duplicated code though some of it will be unavoidable. NOTE: This may not actually move all eDP panels over to the new driver since not all panels were properly marked with `DRM_MODE_CONNECTOR_eDP`. A future patch will attempt to move wayward panels I could identify but even so there may be some missed.

drm/panel: s6d27a1: Add driver for Samsung S6D27A1 display panel

2021-08-13T13:53:11+00:00

This adds a driver for Samsung S6D27A1 display controller and panel. This panel is found in the Samsung GT-I8160 mobile phone, and possibly some other mobile phones. This display needs manufacturer commands to configure it; the commands used in this driver were taken from downstream driver by Gareth Phillips; sadly, there is almost no documentation on what they actually do. This driver re-uses the DBI infrastructure to communicate with the display. This driver is heavily based on WideChips WS2401 display controller driver by Linus Walleij and on other panel drivers for reference.

drm/panel: Add ilitek ili9341 panel driver

2021-08-05T09:09:23+00:00

This driver combines tiny/ili9341.c mipi_dbi_interface driver with mipi_dpi_interface driver, can support ili9341 with serial mode and parallel rgb interface mode by different dts bindings.

drm/panel: atna33xc20: Introduce the Samsung ATNA33XC20 panel

2021-07-31T18:14:15+00:00

The Samsung ATNA33XC20 panel is an AMOLED eDP panel that has backlight control over the DP AUX channel. This panel is _almost_ able to be controlled in a "simple" way (and it originally was implemented in panel-simple.c), but it's really impossible to get the backlight semantics right there without adding wacky special-case code to panel-simple. Let's give up and clone the parts of panel-simple that we need and implement the power sequence that this panel needs. NOTE: we'll still leave the devicetree bindings alone. Even though the power-sequencing is non-standard the bindings are still "simple".

drm/panel: ws2401: Add driver for WideChips WS2401

2021-07-17T11:10:29+00:00

This adds a driver for panels based on the WideChips WS2401 display controller. This display controller is used in the Samsung LMS380KF01 display found in the Samsung GT-I8160 (Codina) mobile phone and possibly others. As is common with Samsung displays manufacturer commands are necessary to configure the display to a working state. The display optionally supports internal backlight control, but can also use an external backlight. This driver re-uses the DBI infrastructure to communicate with the display.

drm/panel: Add Innolux EJ030NA 3.0" 320x480 panel

2021-07-14T20:49:07+00:00

Add support for the Innolux/Chimei EJ030NA 3.0" 320x480 TFT panel. This panel can be found in the LDKs, RS97 V2.1 and RG300 (non IPS) handheld gaming consoles. While being 320x480, it is actually a horizontal 4:3 panel with non-square pixels in delta arrangement.

drm/panel: db7430: Add driver for Samsung DB7430

2021-06-10T22:43:45+00:00

This adds a new driver for the Samsung DB7430 DPI display controller as controlled over SPI. Right now the only panel product we know that is using this display controller is the LMS397KF04 but there may be more. This is the first regular panel driver making use of the MIPI DBI helper library. The DBI "device" portions can not be used because that code assumes the use of a single regulator and specific timings around the reset pulse that do not match the DB7430 datasheet.
