misc: mic: Remove COSM functionality from the MIC card driver

2015-10-04T11:46:06+00:00

Since card side COSM functionality, to trigger MIC device shutdowns
and communicate shutdown status to the host, is now moved into a
separate COSM client driver, this patch removes this functionality
from the base MIC card driver. The mic_bus driver is also updated to
use the device index provided by COSM rather than maintain its own
device index.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

virtio: allow finalize_features to fail

2014-12-09T14:32:32+00:00

This will make it easy for transports to validate features and return
failure.

virtio: assert 32 bit features in transports

2014-12-09T10:05:24+00:00

At this point, no transports set any of the high 32 feature bits.
Since transports generally can't (yet) cope with such bits, add BUG_ON
checks to make sure they are not set by mistake.

Based on rproc patch by Rusty.

virtio: add support for 64 bit features.

2014-12-09T10:05:24+00:00

Change u32 to u64, and use BIT_ULL and 1ULL everywhere.

Note: transports are unchanged, and only set low 32 bit.
This guarantees that no transport sets e.g. VERSION_1
by mistake without proper support.

mic_virtio: robust feature array size calculation

2014-12-09T10:05:23+00:00

mic reads sizeof(vdev->features) bits from device, but in fact it stores
bits in local features variable. use sizeof(features) to make code
robust against future changes extending sizeof(vdev->features).

virtio: use u32, not bitmap for features

2014-12-09T10:05:23+00:00

It seemed like a good idea to use bitmap for features
in struct virtio_device, but it's actually a pain,
and seems to become even more painful when we get more
than 32 feature bits.  Just change it to a u32 for now.

virtio: unify config_changed handling

2014-10-14T23:54:54+00:00

Replace duplicated code in all transports with a single wrapper in
virtio.c.

The only functional change is in virtio_mmio.c: if a buggy device sends
us an interrupt before driver is set, we previously returned IRQ_NONE,
now we return IRQ_HANDLED.

As this must not happen in practice, this does not look like a big deal.
