drm/panel: visionox-rm69299: Make use of prepare_prev_first

2026-04-17T14:08:29+00:00

The DSI link must be powered up to let panel driver to talk to the panel
during prepare() callback execution. Set the prepare_prev_first flag to
guarantee this.

drm/panel: simple: Correct G190EAN01 prepare timing

2026-03-26T09:00:05+00:00

The prepare timing specified by the G190EAN01 datasheet should be
between 30 and 50 ms. Considering it might take some time for the
LVDS encoder to enable the signal, we should only wait the min.
required time in the panel driver and not the max. allowed time.

drm/panel: himax-hx83102: Add support for DSI DCS backlight control

2026-03-26T09:00:05+00:00

The HTF065H045 panel based on the HX83102 controller does use DCS
commands for controlling backlight brightness. Make the driver fall back
to DCS when no external backlight has been defined in the device tree,
like many other drivers do.

drm/panel: ilitek-ili9806e: add Rocktech RK050HR345-CT106A SPI panel

2026-03-26T09:00:04+00:00

Add support for the Rocktech RK050HR345-CT106A panel based on the
Ilitek ILI9806E controller using the SPI bus.

The driver is designed to be easily extensible to support other panels
with different initialization sequences and display timings by
providing a specific descriptor structure for each model.

drm/panel: ilitek-ili9806e: split core and DSI logic

2026-03-26T09:00:04+00:00

Split the driver to support multiple transport buses. The core logic
(power, GPIO, backlight) is moved to a dedicated core module, while
DSI-specific code is restricted to the DSI module.

Introduce DRM_PANEL_ILITEK_ILI9806E_CORE as a hidden Kconfig symbol
selected by the bus-specific configuration.
