Pull ARM SoC driver updates from Arnd Bergmann:
 "Driver updates for ARM SoCs, including a couple of newly added
  drivers:

   - A new driver for the power management controller on TI Keystone

   - Support for the prerelease "SCPI" firmware protocol that ended up
     being shipped by Amlogic in their GXBB SoC.

   - A soc_device can now be matched using a glob from inside the
     kernel, when another driver wants to know the specific chip it is
     running on and cannot find out from DT, firmware or hardware.

   - Renesas SoCs now support identification through the soc_device
     interface, both in user space and kernel.

   - Renesas r8a7743 and r8a7745 gain support for their system
     controller

   - A new checking module for the ARM "PSCI" (not to be confused with
     "SCPI" mentioned above) firmware interface.

   - A new driver for the Tegra GMI memory interface

   - Support for the Tegra firmware interfaces with their power
     management controllers

  As usual, the updates for the reset controller framework are merged
  here, as they tend to touch multiple SoCs as well, including a new
  driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp
  interface.

  The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
  Rockchips SoCs see some further updates"

Commit 4fd06960f120 ("Use the new x86 setup code for i386") introduced a
reference to the make variable LINUX_INCLUDE. That reference got moved
around a bit and copied twice and now there are three references to it.

There has never been a definition of that variable. (Presumably that is
because it started out as a mistyped reference to LINUXINCLUDE.) So this
reference has always been an empty string. Let's remove it before it
spreads any further.

Tero Kristo:

[description taken from http://processors.wiki.ti.com/index.php/TISCI

Texas Instruments' Keystone generation System on Chips (SoC) starting
with 66AK2G02, now include a dedicated SoC System Control entity called
PMMC(Power Management Micro Controller) in line with ARM architecture
recommendations. The function of this module is to integrate all system
operations in a centralized location. Communication with the SoC System
Control entity from various processing units like ARM/DSP occurs over
Message Manager hardware block.

...

Texas Instruments' System Control Interface defines the communication
protocol between various processing entities to the System Control Entity
on TI SoCs. This is a set of message formats and sequence of operations
required to communicate and get system services processed from System
Control entity in the SoC.]

Allow disabling PSCI support (mostly for testing purposes) by setting
the status property to "disabled". This makes the node behave in much
the same way as proper device nodes.

On arm and arm64, PSCI is one of the possible firmware interfaces
used for power management. This includes both turning CPUs on and off,
and suspending them (entering idle states).

This patch adds a PSCI checker module that enables basic testing of
PSCI operations during startup. There are two main tests: CPU
hotplugging and suspending.

In the hotplug tests, the hotplug API is used to turn off and on again
all CPUs in the system, and then all CPUs in each cluster, checking
the consistency of the return codes.

In the suspend tests, a high-priority thread is created on each core
and uses low-level cpuidle functionalities to enter suspend, in all
the possible states and multiple times. This should allow a maximum
number of CPUs to enter the same sleep state at the same or slightly
different time.

In essence, the suspend tests use a principle similar to that of the
intel_powerclamp driver (drivers/thermal/intel_powerclamp.c), but the
threads are only kept for the duration of the test (they are already
gone when userspace is started) and it does not require to stop/start
the tick.

While in theory power management PSCI functions (CPU_{ON,OFF,SUSPEND})
could be directly called, this proved too difficult as it would imply
the duplication of all the logic used by the kernel to allow for a
clean shutdown/bringup/suspend of the CPU (the deepest sleep states
implying potentially the shutdown of the CPU).

Note that this file cannot be compiled as a loadable module, since it
uses a number of non-exported identifiers (essentially for
PSCI-specific checks and direct use of cpuidle) and relies on the
absence of userspace to avoid races when calling hotplug and cpuidle
functions.

For now at least, CONFIG_PSCI_CHECKER is mutually exclusive with
CONFIG_TORTURE_TEST, because torture tests may also use hotplug and
cause false positives in the hotplug tests.
