As already demonstrated with PCI [1] and the platform bus [2], a
driver_override property in sysfs can be used to bypass the id
matching of a device to a AMBA driver. This can be used by VFIO to
bind to any AMBA device requested by the user.[1] http://lists-archives.com/linux-kernel/28030441-pci-introduce-new-device-binding-path-using-pci_dev-driver_override.html

CoreSight components are compliant with the ARM CoreSight
architecture specification and can be connected in various
topologies to suit a particular SoC tracing needs. These trace
components can generally be classified as sources, links and
sinks. Trace data produced by one or more sources flows through
the intermediate links connecting the source to the currently
selected sink.The CoreSight framework provides an interface for the CoreSight trace
drivers to register themselves with. It's intended to build up a
topological view of the CoreSight components and configure the
correct serie of components on user input via sysfs.For eg., when enabling a source, the framework builds up a path
consisting of all the components connecting the source to the
currently selected sink(s) and enables all of them.The framework also supports switching between available sinks
and provides status information to user space applications
through the debugfs interface.Signed-off-by: Pratik Patel

2. big.Little support from Nicolas Pitre and Dave Martin
3. support for LPAE systems with all system memory above 4GB
4. Perf updates from Will Deacon
5. Additional prefetching and other performance improvements from Will.
6. Neon-optimised AES implementation fro Ard.
7. A number of smaller fixes scattered around the place.There is a rather horrid merge conflict in tools/perf - I was never
notified of the conflict because it originally occurred between Will's
tree and other stuff. Consequently I have a resolution which Will
forwarded me, which I'll forward on immediately after sending this
mail.The other notable thing is I'm expecting some build breakage in the
crypto stuff on ARM only with Ard's AES patches. These were merged
into a stable git branch which others had already pulled, so there's
little I can do about this. The problem is caused because these
patches have a dependency on some code in the crypto git tree - I
tried requesting a branch I can pull to resolve these, and all I got
each time from the crypto people was "we'll revert our patches then"
which would only make things worse since I still don't have the
dependent patches. I've no idea what's going on there or how to
resolve that, and since I can't split these patches from the rest of
this pull request, I'm rather stuck with pushing this as-is or
reverting Ard's patches.Since it should "come out in the wash" I've left them in - the only
build problems they seem to cause at the moment are with randconfigs,
and since it's a new feature anyway. However, if by -rc1 the
dependencies aren't in, I think it'd be best to revert Ard's patches"I resolved the perf conflict roughly as per the patch sent by Russell,

In DMA support, The received data is not pushed to tty until the DMA buffer
is filled. But some megabyte rate chips such as BT expect fast response and
data should be pushed immediately. In order to fix this issue, We suggest
the use of the timer for polling DMA buffer.
In our test, no data loss occurred at high-baudrate as compared with interrupt-
driven (We tested with 3Mbps).
We changes:- We add timer for polling. If we set poll_timer to 10, every 10ms,
timer handler checks the residue in the dma buffer and transfer data
to the tty. Also, last_residue is updated for the next polling.- poll_timeout is used to prevent the timer's system cost.
If poll_timeout is set to 3000 and no data is received in 3 seconds,
we inactivate poll timer and driver falls back to interrupt-driven.
When data is received again in FIFO and UART irq is occurred, we switch
back to DMA mode and start polling.- We use consistent DMA mappings to avoid from the frequent cache operation
of the timer function for default.- pl011_dma_rx_chars is modified. the pending size is recalculated because
data can be taken by polling.- the polling time is adjusted if dma rx poll is enabled but no rate is
specified. Ideal polling interval to push 1 character at every interval
is the reciprocal of 'baud rate / 10 line bits per character / 1000 ms
per sec'. But It is very aggressive to system. Experimentally,
'10000000 / baud' is suitable to receive dozens of characters. the poll rate
can be specified statically by dma_rx_poll_rate of the platform data as well.Changes compared to v1:
- Use of consistent DMA mappings.
- Added dma_rx_poll_rate in platform data to specify the polling interval.
- Added dma_rx_poll_timeout in platform data to specify the polling timeout.Changes compared to v2:
- Use of consistent DMA mappings for default.
- Added dma_rx_poll_enable in platform data to adjust the polling time
according to the baud rate.
- remove unnecessary lock from the polling function.Signed-off-by: Chanho Min

Pull ARM DMA engine updates from Russell King:
"This looks scary at first glance, but what it is is:
- a rework of the sa11x0 DMA engine driver merged during the previous
cycle, to extract a common set of helper functions for DMA engine

- conversion of amba-pl08x.c to use these helper functions.
- addition of OMAP DMA engine driver (using these helper functions),
and conversion of some of the OMAP DMA users to use DMA engine.Nothing in the helper functions is ARM specific, so I hope that other
implementations can consolidate some of their code by making use of
these helpers.This has been sitting in linux-next most of the merge cycle, and has
been tested by several OMAP folk. I've tested it on sa11x0 platforms,
and given it my best shot on my broken platforms which have the
