MediaTek Cache Coherent Interconnect (CCI) uses software devfreq module
for scaling clock frequency and adjust voltage.
The phandle could be linked between CPU and MediaTek CCI for some
MediaTek SoCs, like MT8183 and MT8186.
The reason we need the link status between cpufreq and MediaTek cci is
cpufreq and mediatek cci could share the same regulator in some MediaTek
SoCs. Therefore, to prevent the issue of high frequency and low voltage,
we need to use this to make sure mediatek cci is ready.

Qualcomm driver updates for v5.19
This converts a wide range of Qualcomm-related DeviceTree bindings to
YAML, in order to improve our ability to validate the DeviceTree source.
The RPMh power-domain driver gains support for the modem platform SDX65,
the compute platform SC8280XP and the automotive platform SA8540p. While
LLCC gains support for SC8180X and SC8280XP and gains a
MODULE_DEVICE_TABLE() to make it functional as a module.
It adds a driver for configuring the SSC bus, providing Linux access to
the hardware blocks in the sensor subsystem.
The socinfo driver gets confusion related to MSM8974 Pro sorted out and
adds new ids for SM8540 and SC7280.
The SCM driver gains support for MSM8974.
Add missing of_node_put() in smp2p and smsm drivers.
Stop using iterator after list_for_each_entry() and define static
definitions as such, in the PDR driver.

The Arm SP810 IP is a "system controller", providing clocks, timer and a
watchdog.
Convert the DT binding to DT schema, to allow automatic validation.
The existing .txt binding described all properties as required, but the
assigned-clock* and clock-output-names are actually not (from a hardware
perspective). The only existing driver I could find (in Linux) doesn't
require them either, so drop those properties from the "required" list.

The Page Request Interface (PRI) is an optional PCIe feature. As such, a
SMMU would not need to handle it if the PCIe host bridge or the SMMU
itself do not implement it. Also an SMMU could be connected to a platform
device, without any PRI functionality whatsoever.
In all cases there would be no SMMU PRI queue interrupt to be wired up
to an interrupt controller.
At the moment, with the "eventq,gerror,priq,cmdq-sync" order, we
would need to sacrifice the command queue sync interrupt as well, which
might not be desired.
Relax the binding to allow specifying certain useful combinations of
wired interrupts, for instance just the "gerror" interrupt, or omitting
both "pri" and "cmdq-sync".

The TA_PROG_SFP supply must be enabled to program the fuses, and
disabled to read the fuses (such as at power-on-reset). On many boards,
this supply is controlled by a jumper. The user must manually insert or
remove it at the appropriate time in the programming process. However,
on other boards this supply is controlled by an FPGA or a GPIO. In
these cases, the driver can automatically enable and disable it as
necessary.

To program fuses, it is necessary to set the fuse programming time. This
is determined based on the value of the platform clock. Add a clock
property.
Because this property is necessary for programming, it is made
mandatory. Since these bindings have not yet been present in a stable
release (though they are on track for 5.18), it is not an ABI break to
change them in this manner.

Most Allwinner SoCs have just one input clock to drive the watchdog
peripheral. So far this is the 24 MHz "HOSC" oscillator, divided down
internally to 32 KHz.
The F1C100 series watchdog however uses the unchanged 32 KHz "LOSC" as
its only clock input, which has the same effect, but let's the binding
description mismatch.
Change the binding description to name the clocks more loosely, so both
the LOSC and divided HOSC match the description. As the fixed clock names
now make less sense, drop them from SoCs supporting just one clock
input, they were not used by any DT anyway.
For the newer SoCs, supporting a choice of two input clocks, we keep
both the description and clock-names requirement.
