| 2025-09-19 | drm/bridge: waveshare-dsi: Fix bailout for devm_drm_bridge_alloc() | Liu Ying | |
| devm_drm_bridge_alloc() returns ERR_PTR on failure instead of a NULL pointer, so use IS_ERR() to check the returned pointer and turn proper error code on failure by using PTR_ERR().

| 2025-08-06 | drm: bridge: Add waveshare DSI2DPI unit driver | Joseph Guo | |
| Waveshare touchscreen consists of a DPI panel and a driver board. The waveshare driver board consists of ICN6211 and a MCU to convert DSI to DPI and control the backlight. This driver treats the MCU and ICN6211 board as a whole unit. It can support all resolution waveshare DSI2DPI based panel, the timing table should come from 'panel-dpi' panel in the device tree.
