Currently, the status register FI2C_SR is checked immediately after a STOP condition is issued in case of the deferred STOP condition.

First of all please stop sending your patches as a reply to an earlier and completely unrelated series. Second please prefix all TTM related patches with "drm/ttm:". Additional to that I don't really see the point in renaming some of the jump labels, if you call it "restart" or "lock_restart"

[PATCH v2 2/2] i2c: octeon: thunderx: Limit register access retries

Do not infinitely retry register readq and writeq operations in order to not lock up the CPU in case the TWSI gets stuck. Return -ETIMEDOUT in case of a failed data read. For all other cases just return so subsequent operations will fail and trigger the recovery. Signed-off-by: Jan Glauber ---
