[Daniel Vetter]

Hi all,

More 4.14 work:

- tons of corner-case fixes for gpu reset/recovery (Chris Wilson)
- refactor power-well code for future platforms (Imre)
- Ycbcr420 support for hdmi 2.0 displays (Shashank Sharma)
- document FBC structs (Paulo Zanoni)
- reduce struct_mutex usage in pinning (Chris Wilson)
- small bits all over, as usual

Happy testing!

Cheers, Daniel
