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"

net: can: mscan: drop owner assignment from platform_drivers

2014-10-20T14:21:01+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

net: can: use kbuild magic to inherit debug settings

2014-08-17T23:03:38+00:00

No need to manually copy debug settings into subdir Makefiles. kbuild
has a mechanism for inheriting, so let's use it.

can: mscan: Fix Kconfig dependencies

2014-05-19T07:38:21+00:00

The only driver based on MSCAN at the moment is for PPC machines,
so it makes no sense to present the menu on M68K. The menu will always
be empty there.

can: Unify MTU settings for CAN interfaces

2014-03-17T08:20:16+00:00

CAN interfaces only support MTU values of 16 (CAN 2.0) and 72 (CAN FD).
Setting the MTU to other values is pointless but it does not really hurt.
With the introduction of the CAN FD support in drivers/net/can a new
function to switch the MTU for CAN FD has been introduced.

This patch makes use of this can_change_mtu() function to check for correct
MTU settings also in legacy CAN (2.0) devices.

net: can: mscan: remove non-CCF code for MPC512x

transition to the common clock framework has completed and the PPC_CLOCK
is no longer available for the MPC512x platform, remove the now obsolete
code path of the mpc5xxx mscan driver which accessed clock control module
registers directly

net: can: mscan: adjust to common clock support for mpc512x

2014-01-12T17:53:05+00:00

implement a .get_clock() callback for the MPC512x platform which uses
the common clock infrastructure (eliminating direct access to the clock
control registers from within the CAN network driver), and provide the
corresponding .put_clock() callback to release resources after use

acquire both the clock items for register access ("ipg") as well as for
wire communication ("can")

keep the previous implementation of MPC512x support in place during
migration, this results in a readable diff of the change

this change is neutral to the MPC5200 platform

can: Fix FSF address in file headers

2013-12-17T10:47:21+00:00

Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL  so that we do not have to keep
updating the header comments anytime the address changes.
