Subject: [PATCH v2 0/4] media: imx: Add support for BT.709 encoding
Date: Fri,  8 Feb 2019 11:19:24 -0800	[thread overview]
Message-ID: <20190208191928.13273-1-steve_longerbeam@mentor.com> (raw)

This patchset adds support for the BT.709 encoding and inverse encoding
matrices to the ipu_ic task init functions. The imx-media driver can
now support both BT.601 and BT.709 encoding.

History:
v2:
- rename ic_csc_rgb2rgb matrix to ic_csc_identity.
- only return "Unsupported YCbCr encoding" error if inf != outf,
  since if inf == outf, the identity matrix can be used. Reported
  by Tim Harvey.
- 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.
