i2c-algo-bit: Fix spurious SCL timeouts under heavy load

2012-03-15T17:11:05Z

When the system is under heavy load, there can be a significant delay between the getscl() and time_after() calls inside sclhi(). That delay may cause the time_after() check to trigger after SCL has gone high, causing sclhi() to return -ETIMEDOUT. To fix the problem, double check that SCL is still low after the timeout has been reached, before deciding to return -ETIMEDOUT.

i2c: mxs: only flag completion when queue is completely done

2012-02-24T21:28:27Z

The hardware generates an interrupt for every completed command in the queue while the code assumed that it will only generate one interrupt when the queue is empty. So, explicitly check if the queue is really empty. This patch fixed problems which occurred due to high traffic on the bus. While we are here, move the completion-initialization after the parameter error checking. Signed-off-by: Wolfram Sang Cc: Shawn Guo Cc: Marek Vasut Cc: Lothar Waßmann Cc: stable@kernel.org
