Thanks very much for your reply, Philipp.

In fact, I have confirmed if there is any existed same patch in
lore.kernel.org before I begin to send my patch.

So there is indeed a patch reported by Miaoqian for imx_src_init().
However, that patch does not consider the bug in imx7_src_init().

Thanks again.

Liang
