i2c-nomadik: Do not use _interruptible_ variant call

2011-09-19T13:15:28+00:00

If there is a signal pending and wait_for_completion_interruptible_timeout exited because of the -ERESTARTSYS error we are unable to send any more i2c messages. So, deprecate this _interruptible_ variant call.

i2c-nomadik: Reset the hw after status check

In case of I2C timeout, reset the HW only after the HW status is read, otherwise the staus will be lost.

i2c-nomadik: Add code to retry on timeout failure and set i2c clock to 400KHz

2011-09-19T13:14:36+00:00

It is seen that i2c-nomadik controller randomly stops generating the interrupts leading to a i2c timeout. As a workaround to this problem add retries, to the on going transfer on failure. Since this behaviour does not get changed with a wait for longer duration, the timeout can be reduced to a lower value, leading to a quicker retry attempt.
