Why is the From different from the Signed-off-by? Would also need a full name.
If the patch is from you, please just use the same From as for the Signed-off-by.

I've just Cc'ed you on 2 patches adding a SGRF_GATE clock-type. Please
use that as base for you rk3328-wdt-clock, so that we don't introduce more
boilderplate code.

please split the addition of the clock-id into a separate patch only adding
said id.
