Do I understand correctly that we need to fix the bank number before we can add
the device tree changes. And that the last two patches are enhancements for the
driver but needed to get a working version?

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 add the patch "fix bank number settings "
first.222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222

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
