This adds rockchip,rk3588-dfi to the list of compatibles. Unlike ealier
SoCs the rk3588 has four interrupts (one for each channel) instead of
only one, so increase the number of allowed interrupts to four.

This adds the rockchip,rk3568-dfi compatible to the binding. Make clocks
optional for this SoC as the RK3568 doesn't have a kernel controllable

Pull devfreq changes for 5.19-rc1 from Chanwoo Choi:
"1. Update devfreq core
- Add cpu based scaling support to passive governor. Some device like
cache might require the dynamic frequency scaling. But, it has very
tightly to cpu frequency. So that use passive governor to scale
the frequency according to current cpu frequency.
To decide the frequency of the device, the governor does one of the following:
: Derives the optimal devfreq device opp from required-opps property of
the parent cpu opp_table.
: Scales the device frequency in proportion to the CPU frequency. So, if
the CPUs are running at their max frequency, the device runs at its
max frequency. If the CPUs are running at their min frequency, the
device runs at its min frequency. It is interpolated for frequencies
in between.
2. Update devfreq drivers
- Update rk3399_dmc.c as following:
: Convert dt-binding document to YAML and deprecate unused properties.
: Use Hz units for the device-tree properties of rk3399_dmc.
: rk3399_dmc is able to set the idle time before changing the dmc clock.
Specify idle time parameters by using nano-second unit on dt bidning.
: Add new disable-freq properties to optimize the power-saving feature
of rk3399_dmc.
: Disable devfreq-event device on remove() to fix unbalanced
enable-disable count.
: Use devm_pm_opp_of_add_table()
: Block PMU (Power-Management Unit) transitions when scaling frequency
by ARM Trust Firmware in order to fix the conflict between PMU and DMC
(Dynamic Memory Controller)."

I want to add, deprecate, and bugfix some properties, as well as add the
first users. This is easier with a proper schema.
The transformation is mostly straightforward, plus a few notable tweaks:
* Renamed rockchip,dram_speed_bin to rockchip,ddr3_speed_bin. The
driver code and the example matched, but the description was
different. I went with the implementation. Note that this property is
also slated for deprecation/deletion in the subsequent patches.
* Drop upthreshold and downdifferential properties from the example.
These were undocumented (so, wouldn't pass validation), but were
representing software properties (governor tweaks). I drop them from
the driver in subsequent patches.
* Rename clock from pclk_ddr_mon to dmc_clk. The driver, DT example,
and all downstream users matched -- the binding definition was the
exception. Anyway, "dmc_clk" is a more appropriately generic name.
* Choose a better filename and location (this is a memory controller).

Pull more power management updates from Rafael Wysocki:
"These are mostly ARM cpufreq driver updates, including one new
MediaTek driver that has just passed all of the reviews, with the
addition of a revert of a recent intel_pstate commit, some core
cpufreq changes and a DT-related update of the operating performance
points (OPP) support code.
Specifics:
- Add new cpufreq driver for the MediaTek MT6779 platform called
mediatek-hw along with corresponding DT bindings (Hector.Yuan).
- Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara
Gopinath).
- Make the qcom-cpufreq-hw driver set the dvfs_possible_from_any_cpu
policy flag (Taniya Das).
- Blocklist more Qualcomm platforms in cpufreq-dt-platdev (Bjorn
Andersson).
- Make the vexpress cpufreq driver set the CPUFREQ_IS_COOLING_DEV
flag (Viresh Kumar).
- Add new cpufreq driver callback to allow drivers to register with
the Energy Model in a consistent way and make several drivers use
it (Viresh Kumar).
- Change the remaining users of the .ready() cpufreq driver callback
to move the code from it elsewhere and drop it from the cpufreq
core (Viresh Kumar).
- Revert recent intel_pstate change adding HWP guaranteed performance
change notification support to it that led to problems, because the
notification in question is triggered prematurely on some systems
(Rafael Wysocki).
- Convert the OPP DT bindings to DT schema and clean them up while at
it (Rob Herring)"
