NFC: RFKILL support

2013-04-12T14:54:45+00:00

All NFC devices will now get proper RFKILL support as long as they provide
some dev_up and dev_down hooks. Rfkilling an NFC device will bring it down
while it is left to userspace to bring it back up when being rfkill unblocked.
This is very similar to what Bluetooth does.

NFC: Prevent polling when device is down

2013-04-11T14:29:10+00:00

Some devices turn radio on whenever they're asked to start a poll.
To prevent that from happening, we just don't call into the driver
start_poll hook when the NFC device is down.

Merge tag 'driver-core-3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2013-02-21T20:05:51+00:00

Pull driver core patches from Greg Kroah-Hartman:
 "Here is the big driver core merge for 3.9-rc1

  There are two major series here, both of which touch lots of drivers
  all over the kernel, and will cause you some merge conflicts:

   - add a new function called devm_ioremap_resource() to properly be
     able to check return values.

   - remove CONFIG_EXPERIMENTAL

  Other than those patches, there's not much here, some minor fixes and
  updates"

driver-core: constify data for class_find_device()

2013-02-06T20:18:56+00:00

All in-kernel users of class_find_device() don't really need mutable
data for match callback.

In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c)
this patch changes match callbacks to use const search data.

The const is propagated to rtc_class_open() and power_supply_get_by_name()
parameters.

Note that there's a dev reference leak in suspend_test.c that's not
touched in this patch.

NFC: Initial Secure Element API

2013-01-09T23:51:54+00:00

Each NFC adapter can have several links to different secure elements and
that property needs to be exported by the drivers.
A secure element link can be enabled and disabled, and card emulation will
be handled by the currently active one. Otherwise card emulation will be
host implemented.

NFC: Fixed nfc core and hci unregistration and cleanup

2013-01-09T23:51:48+00:00

When an adapter is removed, it will unregister itself from hci and/or
nfc core. In order to do that safely, work tasks must first be canceled
and prevented to be scheduled again, before the hci or nfc device can be
destroyed.

NFC: Use IDR library to assing NFC devices IDs

2012-10-26T16:26:51+00:00

As a consequence the NFC device IDs won't be increasing all the time,
as IDR provides the first available ID.

NFC: Set rf_mode to NFC_RF_NONE where necessary

2012-10-26T16:26:47+00:00

rf_mode is now set to NFC_RF_NONE when a device gets allocated,
when the link goes down, and when stop polling.

NFC: HCI check presence must not fail when driver doesn't support it

2012-10-26T16:26:46+00:00

When the driver does not support checking the tag is still present, it
must return -EOPNOTSUPP. The NFC Core will then stop asking and not
report a tag lost event to user space.
