This indeed simplifies the code, but I think the logic is wrong in the
first place. Shouldn't this be
reg = rkisp1_read(rkisp1, RKISP1_CIF_MI_XTD_FORMAT_CTRL);
if (cap->pix.cfg->uv_swap)
reg |= RKISP1_CIF_MI_XTD_FMT_CTRL_SP_CB_CR_SWAP;
else
reg &= ~RKISP1_CIF_MI_XTD_FMT_CTRL_SP_CB_CR_SWAP;
rkisp1_write(rkisp1, reg, RKISP1_CIF_MI_XTD_FORMAT_CTRL);
? Same for patch 1/5.
