all :

0 x12 hstart
0 x13 vstart
0 x15 hsize ( hsize = register - value * 16 )
0 x16 vsize ( vsize = register - value * 16 )
0 x17 bit 0 toggle compression quality ( according to sn9c102 driver )
0 x18 bit 7 enables compression , bit 4 - 5 set image down scaling :
00 scale 1 , 01 scale 1 / 2 , 10 , scale 1 / 4
0 x19 high - nibble is sensor clock divider , changes exposure on sensors which
use a clock generated by the bridge . Some sensors have their own clock .
0 x1c auto_exposure area ( for avg_lum ) startx ( startx = register - value * 32 )
0 x1d auto_exposure area ( for avg_lum ) starty ( starty = register - value * 32 )
0 x1e auto_exposure area ( for avg_lum ) stopx ( hsize = ( 0 x1e - 0 x1c ) * 32 )
0 x1f auto_exposure area ( for avg_lum ) stopy ( vsize = ( 0 x1f - 0 x1d ) * 32 )
