The current ARM PMU binding relies on the PMU interrupts being listed in
CPU logical order, which the device-tree author simply cannot know
anything about.
This patch introduces a new "interrupt-affinity" property, which makes
the relationship between the PMU interrupts and their corresponding
CPU explicit.

NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3
variants of the ethss subsystem, 9 port, 5 port and 2 port. These have
one host port towards the CPU and N external slave ports.
To customize the driver for these new ethss sub systems, multiple
compatibility strings are introduced. Currently some of parameters that
are different on different variants such as number of ALE ports, stats
modules and number of ports are defined through constants. These are now
changed to variables in gbe_priv data that get set based on the
compatibility string. This is required as there are no hardware
identification registers available to distinguish among the variants
of NetCP 1.5 ethss. However there is identification register available
to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use
of in the code to differentiate them.

Conflicts:
drivers/net/ethernet/emulex/benet/be_main.c
net/core/sysctl_net_core.c
net/ipv4/inet_diag.c
The be_main.c conflict resolution was really tricky. The conflict
hunks generated by GIT were very unhelpful, to say the least. It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().
So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged. And this worked beautifully.
The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.

This wont the last 4.1 bluetooth-next pull request, but we've piled up
enough patches in less than a week that I wanted to save you from a
single huge "last-minute" pull somewhere closer to the merge window.
The main changes are:
- Simultaneous LE & BR/EDR discovery support for HW that can do it
- Complete LE OOB pairing support
- More fine-grained mgmt-command access control (normal user can now do
harmless read-only operations).
- Added RF power amplifier support in cc2520 ieee802154 driver
- Some cleanups/fixes in ieee802154 code
Please let me know if there are any issues pulling. Thanks.

The TI CC2521 is an RF power amplifier that is designed to interface
with the CC2520. Conveniently, it directly interfaces with the CC2520
and does not require any pins to be connected to a
microcontroller/processor. Adding a CC2591 increases the CC2520's range,
which is useful for border router and other wall-powered applications.
Using the CC2591 with the CC2520 requires configuring the CC2520 GPIOs
that are connected to the CC2591 to correctly set the CC2591 into TX and
RX modes. Further, TI recommends that the CC2520_TXPOWER and
CC2520_AGCCTRL1 registers are set differently to maximize the CC2591's
performance. These settings are covered in TI Application Note AN065.
This patch adds an optional `amplified` field to the cc2520 entry in the
device tree. If present, the CC2520 will be configured to operate with a
CC2591.
The expected pin mapping is:
CC2520 GPIO0 --> CC2591 EN
CC2520 GPIO5 --> CC2591 PAEN

Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as
Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC).
And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine.
But, in result of DMA ML discussion, 2nd DMAC was concluded that it is
not a general purpose DMAC (2nd DMAC is for Device to Device inside
sound system). Additionally, current DMAEngine can't support Device to
Device, and we don't have correct DT bindings for it at this point.
So the easiest solution for it is that move it from DMAEngine to rsnd
driver.
Audio DMAC peri peri on DMAEngine is no longer needed. remove it.

Scorpion supports a set of local performance monitor event
selection registers (LPM) sitting behind a cp15 based interface
that extend the architected PMU events to include Scorpion CPU
and Venum VFP specific events. To use these events the user is
expected to program the lpm register with the event code shifted
into the group they care about and then point the PMNx event at
that region+group combo by writing a LPMn_GROUPx event. Add
support for this hardware.
Note: the raw event number is a pure software construct that
allows us to map the multi-dimensional number space of regions,
groups, and event codes into a flat event number space suitable
for use by the perf framework.
This is based on code originally written by Sheetal Sahasrabudhe,
Ashwin Chaugule, and Neil Leeder [1].
