mei: make device disabled on stop unconditionally

2015-03-12T16:31:10+00:00

commit 6c15a8516b8118eb19a59fd0bd22df41b9101c32 upstream.

Set the internal device state to to disabled after hardware reset in stop flow.
This will cover cases when driver was not brought to disabled state because of
an error and in stop flow we wish not to retry the reset.

mei: use hbm idle state to prevent spurious resets

2014-02-06T19:22:17+00:00

commit 66ae460b13c31a176b41550259683c841a62af3e upstream.

When reset is caused by hbm protocol mismatch or timeout
we might end up in an endless reset loop and hbm protocol
will never sync

mei: cancel stall timers in mei_reset

2013-09-26T20:56:53+00:00

Unset init_clients_timer and amthif_stall_timers
in mei_reset in order to cancel timer ticking and hence
avoid recursive reset calls.

mei: don't get stuck in select during reset

2013-07-27T00:54:30+00:00

Clear pending connection after hw reset but before hw start
and wake up the waiting task in poll. Signal POLLERR in select
when device went through reset.

Add wrapper mei_cl_is_connected for checking if
the device and client are connected.

mei: wake also writers on reset

2013-07-25T05:49:57+00:00

wake writers otherwise might have processes waiting
endlessly on wait_tx during reset

mei: don't have to clean the state on power up

2013-07-24T02:31:35+00:00

When powering up, we don't have to clean up the device state
nothing is connected.

mei: check whether hw start has succeeded

2013-06-24T23:33:28+00:00

hw start may fail therefore the reset flow has
to check for the return value

mei: check if the hardware reset succeeded

2013-06-24T23:32:31+00:00

The hw may have multiple steps for resetting
so we need to check if it has really succeeded.
