a727eaf64f ARM: SoC driver changes
SoC-near driver changes that we're merging through our tree. Mostly
 because they depend on other changes we have staged, but in some cases
 because the driver maintainers preferred that we did it this way.
 
 This contains a largeish cleanup series of the omap_l3_noc bus driver,
 cpuidle rework for Exynos, some reset driver conversions and a long
 branch of TI EDMA fixes and cleanups, with more to come next release.
 
 The TI EDMA cleanups is a shared branch with the dmaengine tree, with
 a handful of Davinci-specific fixes on top.
 
 After discussion at last year's KS (and some more on the mailing lists),
 we are here adding a drivers/soc directory. The purpose of this is
 to keep per-vendor shared code that's needed by different drivers but
 that doesn't fit into the MFD (nor drivers/platform) model. We expect
 to keep merging contents for this hierarchy through arm-soc so we can
 keep an eye on what the vendors keep adding here and not making it a
 free-for-all to shove in crazy stuff.

825f4e0271 ARM: SoC updates for 3.16 (part 1)
A quite large set of SoC updates this cycle. In no particular order:
 
 - Multi-cluster power management for Samsung Exynos, adding support for
   big.LITTLE CPU switching on EXYNOS5
 - SMP support for Marvell Armada 375 and 38x
 - SMP rework on Allwinner A31
 - Xilinx Zynq support for SOC_BUS, big endian
 - Marvell orion5x platform cleanup, modernizing the implementation and
   moving to DT.
 - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
   that their platform can be enabled in the same kernel binary as most
   of the other v7 platforms in the tree. \o/ The work isn't quite complete,
   there's some driver fixes still needed, but the basics now work.
 
 New SoC support added:
 - Freescale i.MX6SX
 - LSI Axxia AXM55xx SoCs
 - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
 - STi STIH407
 
 Plus a large set of various smaller updates for different platforms. I'm
 probably missing some important one here.

a3e01e8022 power: reset: keystone-reset: introduce keystone reset driver
The keystone SoC can be rebooted in several ways. By external reset
pin, by soft and by watchdogs. To allow keystone SoC reset if
watchdog is triggered we have to enable it in reset mux configuration
register regarding of watchdog configuration. Also we need to set
soft/hard reset we are going to use.

So add keystone reset driver to handle all this stuff.

650052b141 Merge branch 'axxia/soc' into next/soc
Patches from Anders Berg applied individually:

Here is version 4 of platform support for AXM5516 SoC.

The clk driver is now applied to clk-next. The rest should be ready for
arm-soc. Haven't got any response from the power/reset maintainers... I hope
this driver can be taken via arm-soc as well.

The AXM55xx family consists of devices that may contain up to 16 ARM Cortex-A15
cores (in a 4x4 cluster configuration). The cores within each cluster share an
L2 cache, and the clusters are connected to each other via a CCN-504 cache
coherent interconnect.

This machine requires CONFIG_ARM_LPAE enabled as all peripherals are located
above 4GB in the memory map.

  ARM: dts: axxia: Add reset controller
  power: reset: Add Axxia system reset driver

3b9334ac83 mfd: vexpress: Convert custom func API to regmap
Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).

Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:

* a rework (and move to drivers/bus directory, as suggested
  by Samuel and Arnd) of the config bus core, which is much
  simpler now and uses device model infrastructure (class)
  to keep track of the bridges; non-DT case (soon to be
  retired anyway) is simply covered by a special device
  registration function

* the new config-bus driver also takes over device population,
  so there is no need for special matching table for
  of_platform_populate nor "simple-bus" hack in the arm64
  model dtsi file (relevant bindings documentation has
  been updated); this allows all the vexpress devices
  fit into normal device model, making it possible
  to remove plenty of early inits and other hacks in
  the near future

* adaptation of the syscfg bridge implementation in the
  sysreg driver, again making it much simpler; there is
  a special case of the "energy" function spanning two
  registers, where they should be both defined in the tree
  now, but backward compatibility is maintained in the code

* modification of the relevant drivers:

  * hwmon - just a straight-forward API change
  * power/reset driver - API change
  * regulator - API change plus error handling
    simplification
  * osc clock driver - this one required larger rework
    in order to turn in into a standard platform driver

d08b80373c power/reset: vexpress: Fix restart/power off operation
The restart/power off implementation in the vexpress driver
used to obtain the config function when necessary. This was
wrong in two respects:

1. It required memory allocation with disabled interrupts
(it worked, but lockdep - when enabled - reported warnings).

2. Used jiffies-based timeout, while jiffies are not running
at this stage of system shutdown (therefore a config
transaction error - if happened - would have never be reported).

Fixed by pre-allocating the config function per device
and using mdelay for timeout.

200c0a3e40 Power: Reset: Generalize qnap-poweroff to work on Synology devices.
The Synology NAS devices use a very similar mechanism to QNAP NAS
devices to power off. Both send a single charactor command to a PIC,
over the second serial port. However the baud rate and the command
differ. Generalize the driver to support this.

ac323d8d80 power: max17040: Fix NULL pointer dereference when there is no platform_data
Fix NULL pointer dereference of "chip->pdata" if platform_data was not
supplied to the driver.

The driver during probe stored the pointer to the platform_data:
	chip->pdata = client->dev.platform_data;
Later it was dereferenced in max17040_get_online() and
max17040_get_status().

If platform_data was not supplied, the NULL pointer exception would
happen:

5c49a6256b charger-manager: Modify the way of checking battery's temperature
Charger-manager driver used to check battery temperature through the
callback function passed by platform data. Unfortunatley, without that
pre-defined callback function, charger-manager can't get battery's
temperature at all. Also passing callback function through platform data
ruins DT support for charger-manager.

This patch mondifies charger-manager driver to get temperature of battery
without pre-defined callback function. Now, charger-manager can use either
of battery thermometer in fuel-gauge and ouside of battery. It uses
thermal framework interface for outer thermometer if thermal fw is
enabled. Otherwise, it tries to use fuel-gauge's through the power supply
interface.

This would help to take some actions in those drivers on changing the
power supply properties. One such scenario is to increase/decrease system
performance based on the battery capacity/voltage. Another scenario is to
adjust the h/w peak current detection voltage/current thresholds based on
battery voltage/capacity. The notifier helps drivers to listen to changes

80c6463e2f power_supply: Fix Oops from NULL pointer dereference from wakeup_source_activate
power_supply_register() calls device_init_wakeup() to register a wakeup
source before initializing dev_name. As a result, device_wakeup_enable()
end up registering wakeup source with a null name when
wakeup_source_register() gets called with dev_name(dev) which is null at
the time.

When kernel is booted with wakeup_source_activate enabled, it will panic
when the trace point code tries to dereference ws->name.

Fixed the problem by moving up the kobject_set_name() call prior to
accesses to dev_name(). Replaced kobject_set_name() with dev_set_name()
which is the right interface to be called from drivers. Fixed the call to
device_del() prior to device_add() in for wakeup_init_failed error
handling code.

Trace after the change:

3ed5cd79b8 bq2415x_charger: Fix max battery regulation voltage
As per the datasheets, maximum battery regulation voltage is 4440mV.

The formula is (voltage - offset) / step, so the maximum value is:
(4440 - 3500) / 20 = 47
