Subject: [Intel-gfx] [PATCH 10/13] drm/i915: Reuse ilk_needs_fb_cb_tune() for the reduced clock as well
Date: Thu, 15 Jul 2021 12:35:27 +0300	[thread overview]
Message-ID: <20210715093530.31711-11-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20210715093530.31711-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Use ilk_needs_fb_cb_tune() for reduced_clock instead of hand rolling
it. Also ilk_needs_fb_cb_tune() can just use the precomputed M value
instead of calculating it again.
