📝 Walkthrough

Walkthrough

This patch adds a new DDIC CH13726A DSI panel driver to the DRM framework. It introduces build configuration via Kconfig and Makefile entries, implements a complete panel driver with power management, GPIO reset, regulator control, backlight support, and two display modes, and adjusts DSI mode flags to exclude VIDEO_BURST mode.
