Instead of clearing 2 bits, all the other bits were set because '|=' was used instead of '&='.

This series was tested on a sabrelite and a i.mx51 board
Sigh, I should test it on the efikamx board. It has some i2c chip that's hard to talk to since it's quite sensitive to the behavior of the bus. But since I'm dead busy now, I'll just trust you. I'm glad you found it, Troy :)
I'd rather have your verification than trust :-) Thanks for the reviews.
Hmm, lemme see.
Troy
Best regards, Marek Vasut
Here's a patch to enable i2c for efikamx....
It should be enabled already ... hm, I think I'll have to dig deeper.
