This change: - fixes writing frame width and height values into CSID_TPG_DT_n_CFG_0 - fixes the shift by one between test_pattern control value and the actual pattern. - drops fixed VC of 0x0a which testing showed prohibited some test patterns in the CSID to produce output. So that TPG starts working, but with the below limitations: - only test_pattern=9 works as it should - test_pattern=8 and test_pattern=7 produce black frame (all zeroes) - the rest of test_pattern's don't work (yavta doesn't get the data) - regardless of the CFA pattern set by 'media-ctl -V' the actual pixel order is always the same (RGGB for any RAW8 or RAW10P format in 4608x2592 resolution).
