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: v4: - fix a compile error in init_csc(), reported by Tim Harvey. v3: - fix some inconsistent From: and Signed-off-by:'s. No functional changes. 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 colorspace for ic_route, otherwise it's not possible to set BT.709 encoding for ic routes.
