3d93f42d44 Merge branch 'clockevents/4.8' of http://git.linaro.org/people/daniel.lezcano/linux into timers/core
Pull the clockevents/clocksource tree from Daniel Lezcano:

  - Convert the clocksource-probe init functions to return a value in order to
    prepare the consolidation of the drivers using the DT. It is a big patchset
    but went through 01.org (kbuild bot), linux next and kernel-ci (continuous
    integration) (Daniel Lezcano)

  - Fix a bad error handling by returning the right value for cadence_ttc
    (Christophe Jaillet)

  - Fix typo in the Kconfig for the Samsung pwm (Alexandre Belloni)

  - Change functions to static for armada-370-xp and digicolor (Ben Dooks)

  - Add support for the rk3399 SoC timer by adding bindings and a slight
    change in the base address. Take the opportunity to add the DYNIRQ flag
    (Huang Tao)

  - Fix endian accessors for the Samsung pwm timer (Matthew Leach)

  - Add Oxford Semiconductor RPS Dual Timer driver (Neil Armstrong)

  - Add a kernel parameter to swich on/off the event stream feature of the arch
    arm timer (Will Deacon)

5d26ad9cfb arm64: dts: rockchip: add ap_pwroff and ddrio_pwroff pins for rk3399
There are two sleep related pins on rk3399: ap_pwroff and ddrio_pwroff.
Let's add the definition of these two pins to rk3399's main dtsi file so
that boards can use them.

These two pins are similar to the global_pwroff and ddrio_pwroff pins in
rk3288 and are expected to be used in the same way: boards will likely
want to configure these pinctrl settings in their global pinctrl hog
list.

Note that on rk3288 there were two additional pins in the "sleep"
section: "ddr0_retention" and "ddr1_retention".  On rk3288 designs these
pins appeared to actually route from rk3288 back to rk3288.  Presumably
on rk3399 this is simply not needed since the pins don't appear to exist
there.

ad1cfdf518 arm64: dts: rockchip: fixes the gic400 2nd region size for rk3368
The 2nd additional region is the GIC virtual cpu interface register
base and size.

As the gic400 of rk3368 says, the cpu interface register map as below

:

-0x0000 GICC_CTRL
.
.
.
-0x00fc GICC_IIDR
-0x1000 GICC_IDR

Obviously, the region size should be greater than 0x1000.
So we should make sure to include the GICC_IDR since the kernel will access
it in some cases.

69e5a8fe8c arm64: dts: rockchip: add i2c nodes for rk3399
We've got 9 (count em!) i2c controllers on rk3399, some of which are in
the PMU power domain and some of which are normal peripherals.  Add them
all to the main rk3399 dtsi file so future patches can turn them on in
the board dts files.

Note: by default we try to set the i2c clock rate to 200 MHz so that we
can achieve good i2c functional clock rates.  200 MHz gives us the
ability to make very close to 100 kHz / 400 kHz / 1 MHz rates.  If
boards want to tune clock rates further they can always override.
Possibly boards could want to tune this if:
- they wanted to save an infinitesimal amount of power and they knew
  their i2c bus was slow anyway.  Since we gate the functional clock
  when the i2c bus is not active, power savings would only be while i2c
  transfers were happening and probably won't be very big anyway.
- they wanted to eek out a bit more speed by carefully tuning the source
  clock to make divisions work out perfectly, accounting for the rise /
  fall time measured on an actual board.

Note also that we still request 200 MHz for the PMU i2c busses even
though we expect that we won't make that exactly (currently PPLL is 676
MHz which gives us 169 MHz).

95c27ba7bd arm64: dts: rockchip: add thermal nodes for rk3399 SoCs
This adds thermal zone and tsadc nodes to rk3399 dtsi, rk3399 thermal
data is including the cpu and gpu sensor zone node.

The thermal zone node is the node containing all the required info
for describing a thermal zone, including its cooling device bindings.
The thermal zone node must contain, apart from its own properties, one
sub-node containing trip nodes and one sub-node containing all the zone
cooling maps.

The following is the parameter is introduced:
* polling-delay:
The maximum number of milliseconds to wait between polls

* polling-delay-passive:
The maximum number of milliseconds to wait between polls when performing
passive cooling.

* trips:
A sub-node which is a container of only trip point nodes required to
describe the thermal zone.

* cooling-maps:
A sub-node which is a container of only cooling device map nodes, used to
describe the relation between trips and cooling devices.

* cooling-device:
A phandle of a cooling device with its specifier, referring to which
cooling device is used in this cooling specifier binding. In the cooling
specifier, the first cell is the minimum cooling state and the second cell
is the maximum cooling state used in this map.

a09906cd8c arm64: dts: rockchip: assign default rates for core rk3399 clocks
These clocks are all core clocks used by many blocks/peripherals, many
of whose drivers don't set their clock rates at all. Let's assign
reasonable default clock rates for these core clocks, so that these
peripherals get something reasonable by default, and also so that if
child devices want to select a clock rate themselves, their muxes have
some reasonable parent clock rates to branch off of (rather than just
the boot-time defaults).

This helps the eMMC PHY, for one, to get a reasonable ACLK rate.

Keyboard driver for GPIO buttons(gpio-keys) checks for the legacy
"gpio-key,wakeup" boolean property to enable gpio buttons as wakeup

Few dts files assign value "1" to gpio-key,wakeup and in one instance a
value "0" is assigned probably assuming it won't be enabled as a wakeup
source. Since the presence of the boolean property indicates it is
enabled, value of "0" have no value.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property which inturn fixes the above mentioned issue.
