[Intel-gfx] [PATCH v2 1/5] drm/i915/icl: Fix combo PHY uninit

2018-11-06 Thread Imre Deak
BSpec says to clear the comp init HW flag too during combo PHY uninit, so do that. The lack of this could badly interact with the PHY reinit after a DC6/9 transition at least, where (after a follow-up patch fixing the init code) we'd skip the initialization incorrectly due to this flag being set.
