can: flexcan: demote register output to debug level

2015-08-20T08:52:54+00:00

This message isn't really helpful for the general reader of the kernel
logs, so should not be printed with info level. All other register
programming outputs in the flexcan driver already use the debug level.

can: flexcan: don't touch skb after netif_receive_skb()

2015-07-15T07:04:27+00:00

There is no guarantee that the skb is in the same state after calling
net_receive_skb() or netif_rx(). It might be freed or reused. Not really
harmful as its a read access, except you turn on the proper debugging options
which catch a use after free.

can: flexcan: add documentation about mailbox organization

2015-05-06T20:57:26+00:00

This patch adds a short documentation snippet about the mailbox organization as
it's regularly not correct in freescale's datasheets.

can: flexcan: add MB/FIFO specific column to comment table of IP versions

2015-05-06T20:57:26+00:00

Flexcan V10 and newer are able to receive RTR frames in a MB. Older versions
are not. Those should use flexcan in FIFO mode.

can: flexcan: Deferred on Regulator return EPROBE_DEFER

2015-03-22T18:20:10+00:00

Return EPROBE_DEFER if Regulator returns EPROBE_DEFER

If the Flexcan driver is built into kernel and a regulator is used to
enable the CAN transceiver, the Flexcan driver may not use the regulator.

When initializing the Flexcan device with a regulator defined in the device
tree, but not initialized, the regulator subsystem returns EPROBE_DEFER, hence
the Flexcan init fails.

The solution for this is to return EPROBE_DEFER if regulator is not initialized
and wait until the regulator is initialized.

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"
