Subject: [Intel-gfx] [PATCH 03/13] drm/i915: Extract ilk_update_pll_dividers()
Date: Thu, 15 Jul 2021 12:35:20 +0300	[thread overview]
Message-ID: <20210715093530.31711-4-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>

Make the PCH dpll code match the gmch code by splitting
the FP register handling out from ilk_compute_dpll().
