[Intel-gfx] [PATCH v2 9/9] drm/i915: Address broxton phy registers based on phy and channel number
Ander Conselvan de Oliveira
ander.conselvan.de.oliveira at intel.com
Thu Oct 6 16:22:22 UTC 2016
The port registers related to the phys in broxton map to different
channels and specific phys. Make that mapping explicit.
v2: Pass enum dpio_phy to macros instead of mmio base. (Imre)
