Subject: [PATCH 09/11] drm/i915/cnl: Enable DDI-F on Cannonlake.
Date: Fri, 22 Dec 2017 14:23:24 -0800	[thread overview]
Message-ID: <20171222222326.18562-9-rodrigo.vivi@intel.com> (raw)
In-Reply-To: <20171222222326.18562-1-rodrigo.vivi@intel.com>

Now let's finish the Port-F support by adding the
proper port F detection, irq and power well support.

v2: Rebase
v3: Use BIT_ULL
v4: Cover missed case on ddi init.
v5: Update commit message.
