[PATCH v2 7/7] drm/panel: himax-hx83102: Support for IVO t109nw41 MIPI-DSI panel

Cong Yang
2024-04-22T09:03:57Z

The IVO t109nw41 is a 11.0" WUXGA TFT LCD panel, use hx83102 controller
which fits in nicely with the existing panel-himax-hx83102 driver. Hence,
we add a new compatible with panel specific config.
