Subject: [PATCH v4 4/4] media: imx: Allow BT.709 encoding for IC routes
Date: Fri, 8 Feb 2019 17:47:48 -0800 [thread overview]
Message-ID: <20190209014748.10427-5-slongerbeam@gmail.com> (raw)
In-Reply-To: <20190209014748.10427-1-slongerbeam@gmail.com>
The IC now supports BT.709 Y'CbCr encoding, in addition to existing BT.601
encoding, so allow both, for pipelines that route through the IC.
Reported-by: Tim Harvey <tharvey@gateworks.com>
Signed-off-by: Steve Longerbeam <slongerbeam@gmail.com>

Changes in v2:
- move ic_route check above default colorimetry checks, and fill default
colorimetry for ic_route, otherwise it's not possible to set BT.709
encoding for ic routes.
