Subject: [PATCH v4 6/8] drm/i915: Add calc_voltage_level display vfunc
Date: Tue, 10 Sep 2019 08:42:50 -0700	[thread overview]
Message-ID: <20190910154252.30503-7-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20190910154252.30503-1-matthew.d.roper@intel.com>

With all of the cdclk function consolidation, we can cut down on a lot
of platform if/else logic by creating a vfunc that's initialized at
startup.
