I did revert the original commit mentioned in the fixes tag for 4.16-rc
but it would nevertheless be really cool if these 2 patches (code + binding)
could make it into your tree for 4.17 :-)

And ideally also with the other 5 patches from Enric starting at
	[PATCH v3 1/6] phy: rockchip-typec: deprecate some DT properties for various register fields.

from 2018-02-16.


Thanks
