I have tested these patches on AM335x EVM, AM335x Beaglebone and OMAP35xx.
I did not face any issues w.r.t these EVM's.
I tried i2c probe, read/write and all of it worked as expected.
Also from the logs in [1] I still see an I2C error " wait_for_bb: I2C_STAT=1000",
which is bus busy indication.

Rachna.
