[PATCH 0/3] thermal/drivers/mediatek/lvts_thermal: add mt7988 lvts commands

[Mason Chang]

Add the LVTS commands for Mediatek Filogic 880/MT7988.

This series fixes severely abnormal and inaccurate LVTS temperature
readings when using the default commands.

Aw: [PATCH 2/3] thermal/drivers/mediatek/lvts_thermal: add lvts commands and their sizes to driver data

[Frank Wunderlich]

Hi Mason,

thank you for working on this.

I have not yet tested the series, but did not have the issue (which should be solved by it) reported [1].

So just my thoughts when looking through changes

could you please move this block in part 1 to the position used here in v2 to avoid deletion/adding again here?

Maybe magic numbers can be described a bit?

Re: Aw: [PATCH 2/3] thermal/drivers/mediatek/lvts_thermal: add lvts commands and their sizes to driver data

[Mason Chang]

Hi Frank,

First of all, thank you for providing the link to the actual issue
case. This issue does not affect all MT7988 ICs. Based on the
information collected from users and production lines, we have found
that about 2% of the ICs show severe temperature anomalies without this
patch.

To clearly separate changes and maintain the principle of minimal
modifications, you can see that in patch [1/3], the functions
lvts_ctrl_connect and lvts_ctrl_initialize call the commands.
Therefore, the commands cannot be moved to the part in patch [2/3].

This is just an initialization sequence, it cannot be adjusted.

Hi all,

I submitted the patch a while ago, but haven't received any response
from the maintainer yet. I would really appreciate it if any maintainer
could take a look or provide some comments.

If there is a more appropriate maintainer or reviewer for this patch,
please kindly let me know or help forward it.

Thank you very much for your time and help!

Sincerely,
Mason

Hi,

i finally found someone for testing this as it only affects ~2% the mt7988 users:

https://github.com/frank-w/BPI-Router-Images/issues/16#issuecomment-3061976373

so can you please review and add it to mainline?

regards Frank
