Is this right? All other use pull = 1.
I guess it's board dependent depending on if there is external pullups
or not on the i2c bus. I have seen Allwinner designs both with and
without external pullups.
It will not work well if there is neither internal or external pullup.
And may stress the i2c components a bit if there is both..
