mei: support for fixed address clients

2015-05-24T18:13:48+00:00

Fixed address is simplified FW client that doesn't require
connection and doesn't support flow control.
So it can be only one host client per fixed FW client.
Fixed client access is available only for drivers on mei bus,
connection from user-space is blocked.

mei: revamp client disconnection flow

2015-05-24T18:13:10+00:00

Split disconnected state into two parts first reception disconnect
response from the firmware and second actually setting of disconnected
state.  Book keeping data are needed for processing and after firmware
disconnected the client and are cleaned when setting the disconnected
state in mei_cl_set_disconneted() function.
Add mei_cl_send_disconnect to reduce code duplication.

mei: replace check for connection instead of transitioning

2015-04-03T14:18:56+00:00

The function mei_cl_is_transitioning is just opposite
of mei_cl_is_connected. What we actually wanted to
check is if we lost connection so we can discard
the check for transition and check for 'not connected'

mei: fix regression on NFC connection

2015-03-25T10:36:37+00:00

In mei_host_client_init function we enable the all internal
connected clients including NFC. This is done before we set the device
to enabled state and let userspace call open.
We need to check only for MEI_FILE_CONNECTED in mei_cl_is_connected
in order to enable the communication with the clients before
MEI_DEV_ENABLED is set.
