The driver supports dual-DSI, DSC, and DCS-based backlight. The overall structure is reasonable and follows existing panel driver patterns (particularly panel-novatek-nt36523.c for dual-DSI). However, there are several issues that need to be addressed: 1. **Major: `module_param` for DSC is a non-standard approach** - no other panel driver in the kernel uses a module parameter to toggle DSC. DSC capability should be determined from the panel descriptor or DT, not a runtime boot parameter that could lead to mismatched panel states. 2. **Major: Supply name mismatch between DT binding and driver code** - the binding defines `avdd-supply`/`avee-supply` but the driver requests `vsp`/`vsn`. 3. **Major: Missing `allOf` reference to `panel-common.yaml`** in the DT binding. 4. **Minor: Kconfig issues** - missing `DRM_DISPLAY_DSC_HELPER` / `DRM_DISPLAY_HELPER` selections needed for DSC helper usage. 5. **Moderate: The `bpc` field is never set** in the panel descriptors. --- --- Generated by Claude Code Patch Reviewer
