Message-ID<rv5OG-5wR-7@gated-at.bofh.it>
Call rk3x_i2c_setup() before rk3x_i2c_start()
and the last thing in setup was to clean the IPD,
so no reason to do it at the beginning of start.

Looks great.  Thanks for splitting this out from other patches--makes
it much more obvious what's happening!  :)

IMHO this can be applied any time independent of any earlier patches.
