- OTG support - Charger - WiFi 5GHz - RTC bug "fixed" (always-on interrupt - made device overheat!) - Kernel version bumped to 5.2.1 - Memory timings - New WM8994 codec board driver (fixes suspend/resume) - Camera's regulator supported now (saves power at least!) - Updated panel driver (still not in mainline, idk why) - MHL support in kernel (fixes boot times and screen, currently disabled in X, not tested) - Other minor kernel chagnes [ci:skip-build]: already built successfully in CI
