2017-03-12mei: remove support for broken parallel readAlexander Usyskin
commit cb97fbbcac15982406e0c74cd5512a8b6fcf10b3 upstream. Parallel reads from multiple threads on a file descriptor are not well defined and racy. It is safer to return to original behavior and simply fail the additional read. The solution is to remove request for next read credit.

2017-01-09mei: request async autosuspend at the end of enumerationAlexander Usyskin
commit d5f8e166c25750adc147b0adf64a62a91653438a upstream. pm_runtime_autosuspend can take synchronous or asynchronous paths, Because we are calling pm_runtime_mark_last_busy just before this most of the cases it takes the asynchronous way. However, when the FW or driver resets during already running runtime suspend, the call will result in calling to the driver's rpm callback and results in a deadlock on device_lock. The simplest fix is to replace pm_runtime_autosuspend with asynchronous pm_request_autosuspend.

2016-10-24mei: txe: don't clean an unprocessed interrupt cause.Alexander Usyskin
SEC registers are not accessible when the TXE device is in low power state, hence the SEC interrupt cannot be processed if device is not awake. In some rare cases entrance to low power state (aliveness off) and input ready bits can be signaled at the same time, resulting in communication stall as input ready won't be signaled again after waking up. To resolve this IPC_HHIER_SEC bit in HHISR_REG should not be cleaned if the interrupt is not processed.

2016-09-27mei: stop the stall timer worker if not neededAlexander Usyskin
The stall timer worker checks periodically if there is a stalled i/o transaction. The issue with the current implementation is that the timer is ticking also when there is no pending i/o transaction.
