This is a 3-patch series adding support for the LXD M9189A LCD panel with MIPI-DSI interface. The series follows the standard Linux kernel pattern for adding a new display panel:

1. **PATCH 1/3**: Adds vendor prefix for LXD Research & Display, LLC
2. **PATCH 2/3**: Adds device tree bindings for the panel
3. **PATCH 3/3**: Adds the actual panel driver implementation

**General Assessment:**

The series is well-structured and follows established patterns for panel driver submissions. The patches are properly ordered (vendor prefix → bindings → driver), which is correct. The code appears to be based on v2 feedback and includes improvements like using `mipi_dsi_multi_context` helpers and fixing regulator handling.

**Positive aspects:**
- Good use of modern DRM panel APIs
- Proper use of multi-context helpers for DSI commands
- Clear separation of concerns
- Includes MAINTAINERS updates
- Has been through multiple review cycles (v3)

**Areas of concern:**
- Some naming inconsistencies between driver name and structure names
- Missing validation in certain code paths
- Some hardcoded values that could benefit from defines or comments
