The imx-media driver can now support both BT.601 and BT.709 encoding. History: v6: - tweak some of the coefficients slightly, they were not getting rounded correctly. - move the introduction of calc_csc_coeffs() to an earlier patch for easier patch readability. v5: - the hard-coded encode coefficients now convert only between full-range quantization. A new function is added to transform the coefficients to limited-range at input or output. - add a bug fix patch for saturation bit in TPMEM register. - add a patch to fully describe input and output colorspace to the IC task init functions. - add imx_media_try_colorimetry(), called at all sink/source pad try_fmt. 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.
