[Intel-gfx] [PATCH 6/6] drm/i915: Only enable DDI IO power domains after enabling DPLL

2017-02-10 Thread Ander Conselvan de Oliveira
According to bspec, the DDI IO power domains should be enabled after enabling the DPLL and mapping it to the DDI. The current order doesn't seem to create problems with Skylake and Kabylake, but causes enable timeouts in Geminilake. Cc: David Weinehall
