[Intel-gfx] [PATCH 00/10] drm/i915: HardWare WorkArounds for gen 9

[Nick Hoath]

Implement a subset of known HardWare WorkArounds for gen 9.

v1: Make gen 9 common patchset, remove non-common w/a's, tidy up
    patch names, tidy up register names (Req: Damien Lespiau).
    Removed invalid WA (Found by
    Arun Siluvery). Removed WaSetHdcUnitClockGatingDisableInUcgctl6
    until feature exists (Found by Jeff Mcgee).

v2: Added stepping check for WAs. Removed WaDisableThreadStallDopClockGating
    as not SKL WA (Found by Damien Lespiau). Don't add WaHdcDisableFetchWhenMasked.
    Rebased as necessary.

v3: Use existing revision id

v4: Rebase to Intel DRM nightly. Moved register bitmap to correct patch.

  drm/i915: ring w/a initialisation for gen 9
  drm/i915: ring w/a gen 9 revision definitions
