[PATCH v2 0/4] drm/panel: simple: add Waveshare LCD panels

[Dmitry Baryshkov]

Waveshare have a serie of DSI panel kits with the DPI or LVDS panel
being attached to the DSI2DPI or DSI2LVDS bridge. Commit 80b0eb11f8e0
("dt-bindings: display: panel: Add waveshare DPI panel support")
described two of them in the bindings and commit 46be11b678e0
("drm/panel: simple: Add Waveshare 13.3" panel support") added
definitions for one of those panels. Add support for the rest of them.

Changes in v2:
- Updated waveshare,dsi2dpi schema to implicitly mention LVDS
  (Krzysztof)
- Updated commit message to explain why the ICN6202 / ICN6211 bridges
  are not a part of the DT bindings.
- Link to v1: https://patch.msgid.link/20260330-ws-lcd-v1-0-309834a435c0@oss.qualcomm.com

[PATCH v2 1/4] dt-bindings: display: waveshare,dsp2dpi: describe DSI2LVDS setup

[Dmitry Baryshkov]

Several the Waveshare DSI LCD panel kits use DSI2LVDS ICN6202 bridge
together with the LVDS panels. Define new compatible for the on-kit
bridge setup (it is not itmized and it uses Waveshare prefix since the
rest of the integration details are not known).

Note: the ICN6202 / ICN6211 bridges are completely handled by the board
itself, they should not be programmed by the host (which otherwise might
override correct params), etc. As such, it doesn't make sense to use
those in the compat strings. I consider those to be an internal detail
of the setup.

[PATCH v2 2/4] drm/bridge: waveshare-dsi: support DSI LCD kits with LVDS panels

[Dmitry Baryshkov]

Several Waveshare DSI LCD kits use LVDS panels and the ICN6202 DSI2LVDS
bridge. Support that setup by handling waveshare,dsi2lvds compatible.
The only difference with the existing waveshare,dsi2dpi is the bridge's
output type (LVDS vs DPI).

[PATCH v2 3/4] dt-bindings: display: panel: add Waveshare LCD panels

[Dmitry Baryshkov]

Waveshare has a family of LVDS / DPI panels bundled with the DSI2DPI or
DSI2LVDS bridge. The bridge and the rest of the logic are covered by the
waveshare,dsi2dpi compatible. The bindings already include several
entries for the panels from this series (waveshare,13.3inch-panel,
waveshare,7.0inch-c-panel). Define compatible strings for the rest of
the panels from that series.

[PATCH v2 4/4] drm/panel: simple: add Waveshare LCD panels

[Dmitry Baryshkov]

Waveshare have a serie of DSI panel kits with the DPI or LVDS panel
being attached to the DSI2DPI or DSI2LVDS bridge. The commit
46be11b678e0 ("drm/panel: simple: Add Waveshare 13.3" panel support")
added definitions for one of those panels, describe the rest of them.

Note, since the panels are hidden behind the bridges which are not being
programmed by the kernel, I could not confirm the pixel format for the
panels.
