Hello everyone,
This patch series add support for the Crystal Clear Technology
CMT430B19N00 4.3" 480x272 TFT-LCD panel.
It also adds Crystal Clear Technology to vendor-prefixes.yaml.
Please note that unfortunately there is no public datasheet available
for this panel.
Changes in v3:
- PATCH 3/3: use display_timing structure instead of display_mode
structure as suggested by Maxime Ripard.
- Link to v2: https://lore.kernel.org/all/[email protected]/
Changes in v2:
- add link to the Crystal Clear Technology website in commit message, as
suggested by Conor Dooley and Neil Armstrong.
- Link to v1: https://lore.kernel.org/all/[email protected]/
Regards,
Jérémie

Update Documentation/devicetree/bindings/vendor-prefixes.yaml to
include "cct" as a vendor prefix for "Crystal Clear Technology". CCT is
the vendor of the CMT430B19N00 TFT-LCD panel.
