In the beginning, I only made the patch set of code and dts, the code
patch can work without dts patch due to the default value. The code
patch is merged to media_tree, but mark the dts patch as ´Not
Applicable´. After that, I sent the dts patch again, but maintainer
reminds me that I need to change the binding too. So I made this patch
set. And I guess the dts patch was merged by mistake.

best regards,
Ming
