What's the purpose of this? We're phasing it out on other boards...

Also, no pinctrl to keep gpio5 properly biased? You included a
key_vol_up (with wrong node name...) node though...

This is a deprecated property, and dtbs_check would have pointed that
out as it is not part of gpio-keys.yaml. As mentioned by Krzysztof, did
you run dtbs_check/dt_binding_check?

In the end this looks like a copy-paste of the gpio-keys provided by
sm6125-sony-xperia-seine-pdx201.dts, please apply the same cleanup as

You might want to use labels instead of node names to avoid the mess
discussed in
https://lore.kernel.org/linux-arm-msm/20221209215308.1781047-1-marijn.suijten@somainline.org/

Only for the channels though, not the thermal zones.

sdhci doesn't set a load for vqmmc, only vmmc? Otherwise I'm expecting
an regulator-allow-set-load here similar to l22.

(Also for ufs_mem_hc) does the driver set these loads on the regulators?
If so, shouldn't those have regulator-allow-set-load?
