Merge tag 'arm-drivers-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc 

Pull ARM/SoC driver updates from Arnd Bergmann:
 "These are updates to SoC specific drivers that did not have another
  subsystem maintainer tree to go through for some reason:

   - Some bus and memory drivers for the MIPS P5600 based Baikal-T1 SoC
     that is getting added through the MIPS tree.

   - There are new soc_device identification drivers for TI K3, Qualcomm
     MSM8939

   - New reset controller drivers for NXP i.MX8MP, Renesas RZ/G1H, and
     Hisilicon hi6220

   - The SCMI firmware interface can now work across ARM SMC/HVC as a
     transport.

   - Mediatek platforms now use a new driver for their "MMSYS" hardware
     block that controls clocks and some other aspects in behalf of the
     media and gpu drivers.

   - Some Tegra processors have improved power management support,
     including getting woken up by the PMIC and cluster power down
     during idle.

   - A new v4l staging driver for Tegra is added.

   - Cleanups and minor bugfixes for TI, NXP, Hisilicon, Mediatek, and
     Tegra"

Baikal-T1 CPU or DMAC MMIO requests are handled by the AMBA 3 AXI Interconnect
which routes them to the AXI-APB bridge. This interface is a single master
multiple slaves bus in turn serializing IO accesses and routing them to the
addressed APB slave devices. In case of any APB protocol collisions, slave
device not responding on timeout an IRQ is raised with an erroneous address
reported to the APB terminator (APB Errors Handler Block).

description: |
AXI3-bus is the main communication bus of Baikal-T1 SoC connecting all
high-speed peripheral IP-cores with RAM controller and with MIPS P5600
cores. Traffic arbitration is done by means of DW AXI Interconnect (so
called AXI Main Interconnect) routing IO requests from one block to
another: from CPU to SoC peripherals and between some SoC peripherals
(mostly between peripheral devices and RAM, but also between DMA and
some peripherals). In case of any protocol error, device not responding
an IRQ is raised and a faulty situation is reported to the AXI EHB
(Errors Handler Block) embedded on top of the DW AXI Interconnect and
accessible by means of the Baikal-T1 System Controller.

Required properties:
- clocks: Must contain an entry for the CPU clock.
See ../clocks/clock-bindings.txt for details.
- operating-points-v2: See ../bindings/opp/opp.txt for details.
- #cooling-cells: Should be 2. See ../thermal/thermal.txt for details.
For each opp entry in 'operating-points-v2' table:

On Tegra20:
1. CPU process ID mask
2. SoC speedo ID mask
On Tegra30:
1. CPU process ID mask
2. CPU speedo ID mask
A bitwise AND is performed against these values and if any bit
matches, the OPP gets enabled.

Optional properties:
- cpu-supply: Phandle to the CPU power supply.

regulators {

Baikal-T1 AXI-APB bridge is used to access the SoC subsystem CSRs.
IO requests are routed to this bus by means of the DW AMBA 3 AXI
Interconnect. In case of any APB protocol collisions, slave device
not responding on timeout an IRQ is raised with an erroneous address
reported to the APB terminator (APB Errors Handler Block). This
driver provides the interrupt handler to detect the erroneous
address, prints an error message about the address fault, updates an
errors counter. The counter and the APB-bus operations timeout can be
accessed via corresponding sysfs nodes.

AXI3-bus is the main communication bus connecting all high-speed
peripheral IP-cores with RAM controller and with MIPS P5600 cores on
Baikal-T1 SoC. Traffic arbitration is done by means of DW AMBA 3 AXI
Interconnect (so called AXI Main Interconnect) routing IO requests
from one SoC block to another. This driver provides a way to detect
any bus protocol errors and device not responding situations by
means of an embedded on top of the interconnect errors handler
block (EHB). AXI Interconnect QoS arbitration tuning is currently
unsupported.

Baikal-T1 CPU is based on the MIPS P5600 Warrior IP-core. The CPU
resides Coherency Manager v2 with embedded 1MB L2-cache. It's
possible to tune the L2 cache performance up by setting the data,
tags and way-select latencies of RAM access. This driver provides a
dt properties-based and sysfs interface for it.
