Subject: arm64: dts: rockchip: enable built-in thermal monitoring on RK3588
Include thermal zones information in device tree for RK3588 variants.
This also enables the TSADC controller unconditionally on all boards
to ensure that thermal protections are in place via throttling and
emergency reset, once OPPs are added to enable CPU DVFS.
The default settings (using CRU as the emergency reset mechanism)
should work on all boards regardless of their wiring, as CRU resets
do not depend on any external components. Boards that have the TSHUT
signal wired to the reset line of the PMIC may opt to switch to GPIO
tshut mode instead (rockchip,hw-tshut-mode = <1>;)
It seems though that downstream kernels don't use that, even for
those boards where the wiring allows for GPIO based tshut, such as

Subject: arm64: dts: rockchip: Add OPP data for CPU cores on RK3588
By default the CPUs on RK3588 start up in a conservative performance
mode. Add frequency and voltage mappings to the device tree to enable
dynamic scaling via cpufreq.
OPP values are adapted from Radxa's downstream kernel for Rock 5B [1],
stripping them down to the minimum frequency and voltage combinations
as expected by the generic upstream cpufreq-dt driver, and also dropping
those OPPs that don't differ in voltage but only in frequency (keeping
the top frequency OPP in each case).
Note that this patch ignores voltage scaling for the CPU memory
interface which the downstream kernel does through a custom cpufreq
driver, and which is why the downstream version has two sets of voltage
values for each OPP (the second one being meant for the memory
interface supply regulator). This is done instead via regulator
coupling between CPU and memory interface supplies on affected boards.
This has been tested on Rock 5B with u-boot 2023.11 compiled from
Collabora's integration tree [2] with binary bl31 and appears to be
stable both under active cooling and passive cooling (with throttling)

Subject: arm64: dts: rockchip: Add further granularity in RK3588 CPU OPPs
This introduces additional OPPs that share the same voltage as
another OPP already present in the .dtsi but with lower frequency.
The idea is to try and limit system throughput more gradually upon
reaching the throttling condition for workloads that are close to
sustainable power already, thus avoiding needless performance loss.
My limited synthetic benchmarking [1] showed around 3.8% performance
benefit when these are in place, other things equal (not meant to
be comprehensive). Though dmesg complains about these OPPs being
'inefficient':
