Hello David!

Larry Finger is helping me with a problem and gave me your mail.

I try to make a special hardware working but get and semaphore message:

It would be nice if you have hints or informations.

I tried SEMAPHORE_TIMEOUT set to 300 in
drivers/i2c/busses/i2c-designware-baytrail.c (didng change anyhting)

Thx and bye
