Subject: [PATCH v2 18/18] drm/i915: Do YCbCr 444->420 conversion via DP protocol converters
Date: Fri, 4 Sep 2020 14:53:54 +0300 [thread overview]
Message-ID: <20200904115354.25336-19-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20200904115354.25336-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
For platforms that can't do native 4:2:0 outout we may still be
able to do it by getting the DP->HDMI protocol converter to
perform the 4:4:4->4:2:0 downsamling for us. In this case we
have to configure our hardware to output YCbCr 4:4:4, which we've
already hooked up so all we need to do is flip the switch.
