Subject: [Intel-gfx] [PATCH 10/11] drm/i915: Populate bxt/glk DPLL clock limits a bit more
Date: Tue, 1 Mar 2022 19:31:27 +0200 [thread overview]
Message-ID: <20220301173128.6988-11-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20220301173128.6988-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Set the bxt/glk DPLL min dotclock to 25MHz (HDMI minimum)
and the max to 594 MHz (HDMI max). The supported DP frequencies
(162MHz-540MHz) fit within the same range.
