Yups this looks good too.

I see you pushed the modified solution so I'll go and
test it, thanks a lot! :)

I've made a RFC with a package for the drivetemp previously.



would this work as well?

Cheers,

[OpenWrt-Devel] [PATCH 1/3] gemini: Add v5.4 kernel patches

[Linus Walleij]

This adds the kernel patches needed for the Gemini.
Just 7 patches, 5 of them are already upstream.

Notably we backport the patches to use the temperature
sensor on the hard drive to drive temperature control
of the NAS chassis. This is required for the DIR-685
which has no external temperature sensor.

+Subject: [PATCH 1/7] usb: host: fotg2: add Gemini-specific handling
+
+The Cortina Systems Gemini has bolted on a PHY inside the
+silicon that can be handled by six bits in a MISC register in
+the system controller.
+
+If we are running on Gemini, look up a syscon regmap through
+a phandle and enable VBUS and optionally the Mini-B connector.
+
+If the device is flagged as "wakeup-source" using the standard
+DT bindings, we also enable this in the global controller for
+respective port.
