f0b7d43c8a cc2520: Add support for CC2591 amplifier.
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

341e42c4e3 ARM: perf: Add support for Scorpion PMUs
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].

6981e2af36 ARM: SoC fixes for 4.0-rc3
This is a rather unpleasantly large set of bug fixes for arm-soc,
 Most of them because of cross-tree dependencies for Exynos
 where we should have figured out the right path to merge things
 before the merge window, and then the maintainer being unable to
 sort things out in time during a business trip.
 
 The other changes contained here are the usual collection:
 
 MAINTAINERS file updates
  - Gregory Clement is now a co-maintainer for the legacy Marvell EBU
    platforms
  - A MAINTAINERS entry for the Freescale Vybrid platform that was
    added last year
  - Matt Porter no longer works as a maintainer on Broadcom SoCs
 
 Build-time issues
  - A compile-time error for at91
  - Several minor DT fixes on at91, imx, exynos, socfpga, and omap
  - The new digicolor platform was not correctly enabled at all
 
 Configuration issues
  - Two defconfig fix for regressions using USB on versatile
    express and on OMAP3
  - Enabling all 8 CPUs on Allwinner/SUNxi
  - Enabling the new STiH410 platform to be usable
 
 Bug fixes in platform code
  - A missing barrier for socfpga
  - Fixing LPDDR1 self-refresh mode on at91
  - Fixing RTC interrupt numbers on Exynos3250
  - Fixing a cache-coherency issues in CPU power-down
    on Exynos5
  - Multiple small OMAP power management fixes

USB3 LPM (Link Power Management) capability is hardware property, and

Pull networking fixes from David Miller:

 1) nft_compat accidently truncates ethernet protocol to 8-bits, from
    Arturo Borrero.

 2) Memory leak in ip_vs_proc_conn(), from Julian Anastasov.

 3) Don't allow the space required for nftables rules to exceed the
    maximum value representable in the dlen field.  From Patrick
    McHardy.

 4) bcm63xx_enet can accidently leave interrupts permanently disabled
    due to errors in the NAPI polling exit logic.  Fix from Nicolas
    Schichan.

 5) Fix OOPSes triggerable by the ping protocol module, due to missing
    address family validations etc.  From Lorenzo Colitti.

 6) Don't use RCU locking in sleepable context in team driver, from Jiri
    Pirko.

 7) xen-netback miscalculates statistic offset pointers when reporting
    the stats to userspace.  From David Vrabel.

 8) Fix a leak of up to 256 pages per VIF destroy in xen-netaback, also
    from David Vrabel.

 9) ip_check_defrag() cannot assume that skb_network_offset(),
    particularly when it is used by the AF_PACKET fanout defrag code.
    From Alexander Drozdov.

10) gianfar driver doesn't query OF node names properly when trying to
    determine the number of hw queues available.  Fix it to explicitly
    check for OF nodes named queue-group.  From Tobias Waldekranz.

11) MID field in macb driver should be 12 bits, not 16.  From Punnaiah
    Choudary Kalluri.

12) Fix unintentional regression in traceroute due to timestamp socket
    option changes.  Empty ICMP payloads should be allowed in
    non-timestamp cases.  From Willem de Bruijn.

13) When devices are unregistered, we have to get rid of AF_PACKET
    multicast list entries that point to it via ifindex.  Fix from
    Francesco Ruggeri.

967beb2e87 ASoC: jz4740: Add jz4780 support
The jz4780 and jz4740 have very similar i2s blocks.

The slight difference is in Rx/Tx fifos.
And the bitclocks for input/output are different.

This patch adds jz4780 support to the driver

This commit adds the Device Tree binding documentation to describe the
pin-muxing controller of the Marvell Armada 39x processors. Two
variants are supported for the moment: the 88F6920 (Armada 390) and

73ef85f42d hwmon: (gpio-fan) allow to use alarm support alone from DT
On some boards, such as the LaCie 2Big Network v2 or 2Big NAS (based on
Marvell Kirkwood SoCs), an I2C fan controller is used but the alarm
signal is wired to a separate GPIO. Unfortunately, the gpio-fan driver
can't be used to handle GPIO alarm alone from DT: an error is returned
if the "gpios" DT property is missing.

This patch allows to use the gpio-fan driver even if the "alarm-gpios"
DT property is defined alone.

91c68a7c1d Input: sun4i-ts - A10 (sun4i) has a different temperature curve
Testing has revealed that the temperature in the rtp controller of the A10
(sun4i) SoC has a different curve then on the A13 (sun5i) and later models.

Add a new sun5i-a13-ts compatible to differentiate the newer models and
set the curve based on the compatible string.

The new curve is still not ideal on all A10-s, that seems to have to
do with there being a large spread between different A10-s out there,
the new curve us based on callibration results on 4 completely different
models:
                        raw min raw max temp min temp max stepsize offset
Tong Zhang's hackberry    2402    2680    45.0     80.0    0.125   -255.3
Hansg's Cubieboard        2207    2300    36.0     45.0    0.096   -175.8
Olliver's lime 1 (*):     2258    2537    48.3     87.1    0.139   -265.7
Olliver's lime 2 (*):     2222    2486    46.7     91.7    0.170   -331.0
*) from: http://linux-sunxi.org/Temperature_Calibration

Average all 4:                                             0.133   -257.0
Average without outliers (middle 2):                       0.132   -261.0

Since it is better to slightly overreport the temperature this patch uses
the average of all 4 as curve.

This fixes the temperature reported on the A10 being much higher then
expected.

c8b263cc03 regulator: act8865: add input supply handling
The act88600/act8846/act8865 regulators have a number of input supplies
supplying the individual regulators. This may even be recursively like on
most Rockchip boards using the act8846 where REG4 is most of the time
connected to the inl1-supply.

Therefore add the ability to specify the input supplies for the individual inputs.
The input-names are taken from the datasheets of act8600, act8846 and act8865.
On the act8600 some regulators do not have separate input supplies.
