📝 Walkthrough

Walkthrough

Multiple kernel patches for Sunxi 6.18 are being removed, including six patches for RK3566 PineTab2 device tree customizations (PWM brightness, USB Type-C controller, extcon bridge, charger detection, wifi/UART integration, SPI flash clock) and six RK3399 Type-C support patches (CDN DP, PHY delays, charger detection, USB3 PHY power tracking, Type-C fallback, DWC3 reset quirk). The series configuration is also updated to disable these patches from being applied.

Poem

🐰 Patches once added, now take their leave,
Type-C and brightness—no more reprieve,
The kernel grows lean, the config runs clean,
Removing the clutter that cluttered the scene! 🌱
