As IMX, basically i'd prefer to add pinctrl states in dts file at the
same time within the patch or using a separate patch to add them before
this series to avoid breaking the exist platforms.

However i noted that for mxs, most drivers here are still not dt capable,
so it may be ok to not add their pinctrl state at this time.

But for the patch "serial: amba-pl011: adopt pinctrl support" since it is
dt capable, so with this patch applied, the mx28 dt boot will fail.
Maybe we should at least add pinctrl states for amba-pl011 first.

BTW, will this one break other platforms using this driver?
