mei: bus: complete variable rename of type struct mei_cl_device

2015-09-21T02:31:09+00:00

In the
commit 5c079ae11921 ("mei: bus: fix drivers and devices names confusion")
we set the variables of type struct mei_cl_device to 'cldev'
but few places were left out, namely mei_cl_bus.h header
and the mei nfc drivers.

mei: bus: add and call callback on notify event

2015-08-04T00:30:00+00:00

Enable drivers on mei client bus to subscribe
to asynchronous event notifications.
Introduce events_mask to the existing callback infrastructure
so it is possible to handle both RX and event notification.

mei: bus: enable running fixup routines before device registration

2015-08-04T00:24:16+00:00

Split the device registration into allocation and device struct
initialization, device setup, and the final device registration.
This why it is possible to run fixups and quirks during the setup stage
on an initialized device. Each fixup routine effects do_match flag.
If the flag is set to false at the end the device won't be
registered on the bus.

mei: bus: add me client device list infrastructure

2015-08-04T00:21:59+00:00

Instead of holding the list of host clients (me_cl)
we want to keep the list me client devices (mei_cl_device)
This way we can create host to me client connection only when needed.
Add list head to mei_cl_device and cl_bus_lock
Add bus_added flag to the me client (mei_me_client) to track if
the appropriate mei_cl_device was already created and is_added
flag to mei_cl_device to track if it was already added to the device
list across the bus rescans

mei: bus: add reference to bus device in struct mei_cl_client

2015-08-04T00:21:59+00:00

Add reference to the bus device (mei_device) for easier access.
To ensures that referencing cldev->bus is valid during cldev life time
we increase the bus ref counter on a client device creation and drop it
on the device release.

mei: bus: use ssize_t as the return type for send and receive

2015-01-12T13:04:10+00:00

Mei bus receive and send function may return either number
of transmitted bytes or errno.  It is better to use ssize_t
type for that purpose that mixing size_t with int.
