Pull ARM SoC driver updates from Arnd Bergmann:
"These are all the driver updates for SoC specific drivers. There are a
couple of subsystems with individual maintainers picking up their
patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this tree this
time. There are only minor changes, but they depend on other tegra
driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process. This
depends on a small sound driver change that is included here as
well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains a
mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for the
"Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed BMCs,
something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better
suspend/resume support"
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx,
layerscape, allwinner, broadcom, and omap"

This patch extends sparx5 driver to support also the lan966x. The
process to reset the switch is the same only it has different offsets.
Therefore make the driver more generic and add support for lan966x.

After the retirement of MACH_PISTACHIO, the Pistachio Reset Driver is no
longer auto-enabled when building a kernel for Pistachio systems.
Worse, the driver cannot be enabled by the user at all (unless
compile-testing), as the config symbol is invisible.
Fix this partially by making the symbol visible again when compiling for
MIPS, and dropping the useless default. The user still has to enable
the driver manually when building a kernel for Pistachio systems,
though.

The Sparx5 Switch SoC has a number of components that can be reset
indiviually, but at least the Switch Core needs to be in a well defined
state at power on, when any of the Sparx5 drivers starts to access the
Switch Core, this reset driver is available.
The reset driver is loaded early via the postcore_initcall interface, and
will then be available for the other Sparx5 drivers (SGPIO, SwitchDev etc)
that are loaded next, and the first of them to be loaded can perform the
one-time Switch Core reset that is needed.
The driver has protection so that the system busses, DDR controller, PCI-E
and ARM A53 CPU and a few other subsystems are not touched by the reset.

Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and
SoC-part. Up to a point that N5X uses the same DTSI as Agilex. From
the Linux kernel point of view these are flavors of the same
architecture so there is no need for three top-level arm64
architectures. Simplify this by merging all three architectures into
ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries.
The side effect is that the INTEL_STRATIX10_SERVICE will now be
available for both 32-bit and 64-bit Intel SoCFPGA, even though it is
used only for 64-bit.

The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with
Baoyou Xie and Shawn Guo subsequently becoming maintainers after the
addition of the 64-bit variant.
However, the only machines that were ever supported upstream are the
reference designs, not actual set-top-box devices that would benefit
from this support. All ZTE set-top-boxes from the past few years seem
to be based on third-party SoCs. While there is very little information
about zx296702 and zx296718 on the web, I found some references to other
chips from the same family, such as zx296716 and zx296719, which were
never submitted for upstream support. Finally, there is no support for
the GPU on either of them, with the lima and panfrost device drivers
having been added after work on the zx platform had stopped.
Shawn confirmed that he has not seen any interest in this platform for
the past four years, and that it can be removed.
Thanks to Jun and Shawn for maintaining this platform over the past
five years.

Add a reset controller driver for the Canaan Kendryte K210 SoC. This
driver relies on its syscon compatible parent node (sysctl) for its
register mapping. Default this driver compilation to y when the
SOC_CANAAN option is selected.
The MAINTAINERS file is updated, adding the entry "CANAAN/KENDRYTE K210
SOC RESET CONTROLLER DRIVER" with myself listed as maintainer for this
driver.

Pull ARM SoC driver updates from Arnd Bergmann:
"There are a couple of subsystems maintained by other people that merge
their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power
domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control and SoC
identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660 and
SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs"

Create a separate reset driver that uses the reset operations in
reset-simple. The reset driver for the SoCFPGA platform needs to
register early in order to be able bring online timers that needed
early in the kernel bootup.
We do not need this early reset driver for Stratix10, because on
arm64, Linux does not need the timers are that in reset. Linux is
able to run just fine with the internal armv8 timer. Thus, we use
a new binding "altr,stratix10-rst-mgr" for the Stratix10 platform.
The Stratix10 platform will continue to use the reset-simple platform
driver, while the 32-bit platforms(Cyclone5/Arria5/Arria10) will use
the early reset driver.
