Merge remote-tracking branch 'agust/next' into next

2014-01-29T05:53:55Z

<< Switch mpc512x to the common clock framework and adapt mpc512x drivers to use the new clock driver. Old PPC_CLOCK code is removed entirely since there are no users any more. >>

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

2014-01-12T17:53:05Z

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 Cc: Wolfgang Grandegger Cc: Marc Kleine-Budde Cc: linux-can@vger.kernel.org Signed-off-by: Gerhard Sittig Signed-off-by: Anatolij Gustschin

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

2014-01-12T17:53:05Z

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 Cc: Wolfgang Grandegger Cc: Marc Kleine-Budde Cc: linux-can@vger.kernel.org Signed-off-by: Gerhard Sittig Signed-off-by: Anatolij Gustschin

can: Fix FSF address in file headers

2013-12-17T10:47:21Z

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.

can: Remove extern from function prototypes

2013-09-24T14:09:18Z

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

can: mscan: improve clock API use

2013-08-29T20:49:35Z

the .get_clock() callback is run from probe() and might allocate resources, introduce a .put_clock() callback that is run from remove() to undo any allocation activities prepare and enable the clocks in open(), disable and unprepare the clocks in close() if clocks were acquired during probe(), to not assume knowledge about which activities are done in probe() and remove() use devm_get_clk() to lookup the SYS and REF clocks, to have the clocks put upon device shutdown store pointers to data structures upon successful allocation already instead of deferral until complete setup, such that subroutines in the setup sequence may access those data structures as well to track their resource acquisition since clock allocation remains optional, the release callback as well as the enable/disable calls in open/close are optional as well Cc: linux-can@vger.kernel.org Cc: netdev@vger.kernel.org Signed-off-by: Gerhard Sittig Signed-off-by: Anatolij Gustschin Signed-off-by: Marc Kleine-Budde

can: mscan: add a comment on reg to idx mapping

net: can: use platform_{get,set}_drvdata()

2013-06-03T11:13:49Z

Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure.

can: Kconfig: convert 'depends on CAN_DEV' into 'if CAN_DEV...endif' block

2013-01-26T15:58:58Z

This patch adds an 'if CAN_DEV...endif' Block around the CAN driver symbols in drivers/net/can/Kconfig. So the 'depends on CAN' dependencies can be removed. Signed-off-by: Marc Kleine-Budde

drivers/net: fix up function prototypes after __dev* removals

2012-12-07T19:22:22Z

The __dev* removal patches for the network drivers ended up messing up the function prototypes for a bunch of drivers. This patch fixes all of them back up to be properly aligned. Bonus is that this almost removes 100 lines of code, always a nice surprise. Signed-off-by: Greg Kroah-Hartman Signed-off-by: David S. Miller
