samsung-i927: update kernel to 5.2.1, more updates (!452)
- 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

Subject: [PATCH] drm/tegra: Hacks for S6E63M0
Pins DATA_ENABLE, H_SYNC, V_SYNC, PIXEL_CLOCK are low polarity,
set this in the registers to make the panel working.
