194444c52e ARM: 8441/2: twd: Don't set CLOCK_EVT_FEAT_C3STOP unconditionally
In 5388a6b266 ("ARM: SMP: Always enable clock event broadcast support")
Russell noted that "the TWD local timers are unable to wake up the CPU
when it is placed into a low power mode".

However, some platforms do not stop the TWD block in low-power mode,
and can thus use the TWD timer in one-shot mode, without setting up
a broadcast device.

Make the driver check for the "always-on" boolean property, and set
the CLOCK_EVT_FEAT_C3STOP flag accordingly.

2df7b0f0d2 Documentation: dt: keystone: provide SoC specific compatible flags
Keystone2 devices are used on more platforms than just Texas
Instruments reference evaluation platforms called EVMs. Providing a
generic compatible "ti,keystone" is not sufficient to differentiate
various SoC definitions possible on various platforms for the
following reasons:
a) Userspace applications have no way of knowing which SoC they are
functioning, providing the compatible matches provide a mechanism for
them to enable SoC specific functionality. Such userspace applications
are typically automated test framework or SoC custom hardware
acceleration entitlement from a common file system.
b) Provides an accurate hardware description. This allows
SoC specific logic to be run time handled based on
of_machine_is_compatible("ti,k2hk") or as needed for the dependent
processor instead of needing to use board dependent compatibles that
are needed now.

Hence, provide compatible matches for each SoC in the Keystone family.

0fc197c7cb drivers: firmware: psci: add PSCI v1.0 DT bindings
PSCI 1.0 is designed to be fully compliant to the PSCI 0.2
specification, with minor differences that are described in the
PSCI specification.

In particular, PSCI v1.0 augments the specification with a new
power_state format (extended stateid - probeable through the
PSCI_FEATURES call), changes some function return codes and
functions usage requirements wrt PSCI 0.2. These changes mean
that 1.0 vs 0.2 compliancy should be enforced through a DT
compatible string that allows firmware to specify 1.0 only
compliancy so that older kernels are prevented from using
PSCI 1.0 FW implementations in a non-compatible way (eg by
calling a 1.0 FW implementation and expecting 0.2 behaviour).

This patch adds PSCI 1.0 DT bindings and related compatible
string.

For optimal performance, in a HW I/O coherency context such as the one
used on Armada XP, the shared L2 bit of the CPU configuration register
should be cleared.

This commit adjusts the coherency fabric code used by Marvell EBU
processors to clear this bit on Armada XP. Since it's a per-CPU
register, it's cleared in set_cpu_coherent() for the boot CPU, and
through a CPU notifier for the non-boot CPUs.

a13f18f59d Documentation: arm: Fix typo in the idle-states bindings examples
The idle-states bindings mandate that the entry-method string
in the idle-states node must be "psci" for ARM v8 64-bit systems,
but the examples in the bindings report a wrong entry-method string.
Owing to this typo, some dts in the kernel wrongly defined the
entry-method property, since they likely cut and pasted the example
definition without paying attention to the bindings definitions.

This patch fixes the typo in the DT idle states bindings examples and
respective dts in the kernel so that the bindings and related dts
files are made compliant.

 "Included in this update:

   - moving PSCI code from ARM64/ARM to drivers/

   - removal of some architecture internals from global kernel view

   - addition of software based "privileged no access" support using the
     old domains register to turn off the ability for kernel
     loads/stores to access userspace.  Only the proper accessors will
     be usable.

   - addition of early fixup support for early console

   - re-addition (and reimplementation) of OMAP special interconnect
     barrier

   - removal of finish_arch_switch()

   - only expose cpuX/online in sysfs if hotpluggable

  contents here to avoid the kind of internal conflicts as we got this
  time around, where 32- and 64-bit contents conflicted.

  New SoCs:

   - Broadcom North Star 2 (ns2)
   - Marvell Berlin4CT
   - Mediatek MT6795
   - Rockchip RK3368

  In addition, there are enhancements for the following platforms:

   - Mediatek MT8173: cpuidle-dt updates, misc other additions
   - ZyncMP: A bunch of devices added to the existing DTSI
   - Qualcomm MSM8916 and APQ8016 updates for USB, etc.

 "Ladies and gentlemen, we proudly announce to you the latest branch of
  ARM device tree contents for the mainline kernel.  Come and see, come
  and see!

  No less than twentythree thousand lines of additions! Just imagine the
  joy you will have of using your mainline kernel on newly supported
  hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
  UniPhier hardware!

  For those of you feeling less adventurous, added hardware support on
  platforms such as TI DM814x and Gumstix Overo platforms might be more
  of your liking.

  We've got something for everyone here!

  Ahem.  Cough.  So, anyway...

  This is the usual large batch of DT updates.  Lots and lots of smaller
  changes, some of the larger ones to point out are:

   - Rockchip veyron (Chromebook) support, as well as several other new boards
   - DRM support on Atmel AT91SAM9N12EK
   - USB additions on some Allwinner platforms
   - Mediatek MT6580 support
   - Freescale i.MX6UL support
   - cleanups for Renesas shmobile platforms
   - lots of added devices on LPC18xx
   - lots of added devices and boards on UniPhier

  There's also some dependent code added here, in particular some
  branches that are primarily merged through the clock tree"

62f4771198 clk: versatile: Switch to assigned clock parents
We're removing struct clk from the clk provider API. This code is
calling the consumer APIs to change the parent to a 1 MHz fixed
rate clock for each of the clocks that the driver provides. Move
to using the assigned-clock-parents DT property for this instead.
Because this is an ABI break, detect if the property is missing
and fall back to setting the parent explicitly before the clocks
are registered.
