Subject: [PATCH] drm/i915/cnl: Enable DDI-F on Cannonlake.
Date: Fri, 26 Jan 2018 17:33:30 -0800 [thread overview]
Message-ID: <20180127013330.20124-1-rodrigo.vivi@intel.com> (raw)
In-Reply-To: <20180126224654.yvu4m7mt2uk54fvf@ideak-desk.fi.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.
v6: Rebase on top of display headers rework.
v7: Squash power-well handling related to DDI F to this
patch to avoid warns as pointed out by DK.
v8: Introduce DDI_F_LANES to PG2. (DK)
