The series is two patches: a DT binding= and the driver implementation. The driver has several significant issues that need to be addressed before = it's ready for merge: 1. **The bridge is functionally incomplete** =E2=80=94 it has no MIPI DSI h= ost/device setup, no mode validation, no `atomic_enable`, and no display co= nfiguration. As-is, the driver only handles power sequencing and firmware u= pdates but cannot actually drive a display. 2. **Missing atomic state helpers** =E2=80=94 the `drm_bridge_funcs` uses `= atomic_*` callbacks but doesn't provide `atomic_duplicate_state` / `atomic_= destroy_state` / `atomic_reset`, which are required for correct atomic oper= ation. 3. **The DT binding has swapped port descriptions** relative to both the ex= ample and the driver's port usage. 4. **Regulators are left enabled after probe** and never disabled until the= first `atomic_post_disable`, wasting power. The firmware upgrade code is reasonably structured but has error-handling g= aps and a few correctness issues. --- --- Generated by Claude Code Patch Reviewer
