Hi Matthias,

There is one bank setting of mt8183 config.
If the device tree merged first. I worry that it will crash when the
thermal zone read temperature.
It will access the invalid index of bank.
So please wait the patch "fix bank number settings " merged first.
Thanks!

/* MT8183 thermal sensor data */
static const int mt8183_bank_data[MT8183_NUM_SENSORS] = {
	MT8183_TS1, MT8183_TS2, MT8183_TS3, MT8183_TS4, MT8183_TS5,
MT8183_TSABB
}; 

Best Regards,
Michael
