The driver got added back in 45d7b3867a5cabb97fc31f16122cda8540c3a30c,
but the dts never got updated, so here it is!

I’ve added it to the rk3588s because that’s where most of the
definitions are, but I’ve only tested on a rk3588 so maybe there are
subtle changes.

The rk3588 TRM also documents slightly different values (in part 1
section 14.5.3) than the driver, but I’ve left the values alone since I
have no way to determine which one is (more) correct.

Only the CPU is properly mapped, as neither the GPU nor the NPU have
been added to the dts for now, I’ve left some TODOs there.

All of the thermal zones report almost the same value on my rock-5b
board, I’m not sure if this is due to a programming error or if this is
to be expected.  For instance, after running for a while, all of the
zones report 44384 m℃, despite having used neither the GPU nor the NPU.

Additionally, the alert and crit temperatures have been arbitrarily
chosen based on other dts files, not based on any knowledge of the
thermal behaviours of this specific SoC.

Oh, I wasn’t aware of this work, it seems there is nothing this series
add over Alexey’s so I will drop it.

Is there a document tracking your upstreaming work?  I was planning on
sending a series enabling the VEPU121 hardware encoders next, but if
you’re also working on it I can drop it too (although I don’t see any
series from a quick search).  I’ve now subscribed to the linux-rockchip
mailing list so I shouldn’t miss any new series.

Hi Emmanuel!

I'm currently in a rather more ad-hoc contribution mode, so there is
no tracking document. Here are the things I have in the making:
 - Wire up the GPIO pin that drives WLAN enable signal in the M.2 key
E slot as an rfkill device to make WiFi modules usable on Rock 5B.
Applied locally, tested, submitted [1], not yet reviewed or applied
upstream
 - Add thermal zones managed by the TSADC to RK3588 (the series Daniel
referred to). Applied locally, tested, submitted [2], working on v3 to
incorporate the feedback
 - Wire up the PWM fan as an active cooling device managed by the
thermal code. Applied locally, tested, will submit as part of v3
thermal zones code
 - Add OPP data for CPUs on RK3588 to enable runtime CPU frequency
scaling. Applied locally, testing now, not yet submitted

I also wanted to wire up the display outputs for Rock 5B, given that
VOP support has been recently enabled on RK3588, but haven't yet
started on that one. I haven't touched the hardware encoders either,
so please go ahead with sending those :-)

Best regards,
Alexey
