[PATCH v2 0/3] Add Mediatek thermal driver for mt2701

[PATCH v2 0/3] Add Mediatek thermal driver for mt2701

[Dawei Chien]

This series support for mt2701 chip to mtk_thermal.c,
and integrate both mt8173 and mt2701 on the same driver.
MT8173 has four banks and five sensors, and MT2701 has
only one bank and three sensors.

Change since V1:
1. Restore macro name with MT8173 for nvmem calibration data
since original macro name could be used for both MT2701/MT8173.

2. Add flexible array member to instead of normal array since
thermal bank has different array size between MT2701 to MT8173.

Hmm, does this mean that I should take all these three patches and hold
the patches in next merge window until the above patch has been merged?

thanks,

Patch 3/3 can not be applied on top of upstream kernel, so I guess it
still has some other dependencies.
I think I can apply patch 1, 2 first. And patch 3/3 should be handled
in the dt tree.

Yes, this patch is base on auxadc patchset.

Sorry, this patch is also need Mediatek's clock patchset what I miss to
add in dependency list, I would resend this dt tree once clock patch
merge, or resend this for right dependency on next version, thank you.

Actually, since patch1/patch2 would be OK so far, I would just only
resend patch3 after MTK clock pathcset ready, I prefer to merge
patch1/patch2 if possible, thank you.
