cw1200: Detect "stuck" TX frames at early stage.

2012-05-22T09:06:51+00:00

The patch implements early detection of frames, not acknowledged by firmware. ST-Ericsson ID: 418642 Change-Id: I7af4e2b0aa87a31dd38a3820cb66f5ebc3141978 Signed-off-by: Dmitry Tarnyagin

cw1200: Balance calls to cw1200_pm_(de)init.

2012-05-22T09:06:51+00:00

In case of firmware downloading problem, a call to cw1200_pm_init was not followed by a call to cw1200_pm_deinit. CW1200 PM device was not removed properly due to that and consecutive attempt to initialize driver failed. The patch balances calls to cw1200_pm_(de)init.

cw1200: Avoid sleeping on TX lock for more than 1.5 sec.

2012-05-22T09:06:51+00:00

The patch protects against possible timeout in system suspend code. It implements timestamps for TX frames, and do not wait more than 1.5 sec in total since the oldest frame is sent to firmware. Firmware has to reply within this interval, otherwise driver commits suicide by terminating device communication thread.

cw1200: Do not allow device to suspend when it is not fully awake.

2012-05-22T09:06:51+00:00

Patch fixes a race between device wakeup and device_suspend. The race might confuse state machine in firmware. ST-Ericsson ID: 419543 Change-Id: I07fa22879b3735fe4d5a1f70f5660a693a1b0211 Signed-off-by: Dmitry Tarnyagin

cw1200: Fix for false negatives in suspend decision.

2012-05-22T09:06:51+00:00

There was a race between PM and BH code which sometimes leaded to false negatives in system suspend decision. This race is fixed by this patch.
