Hi Eduardo, Sascha,

Any input on this? I really like to get this driver upstream as it is
currently blocking other Mediatek drivers.
Hi Eduardo,

Do you have any comment about Sascha's response ? We really hope get
your comment since Mediatek thermal driver already reviewed in public
over half years, and we have other patches [0] [1] depend on thermal
driver.

Friendly ping on the Mediatek thermal driver.
The "EFUSE" dependency has now landed in v4.5-rc4.
Actually, it landed in char-misc-next, not v4.5-rc4.

So, AFAICT, the only thing left that may be blocking landing Mediatek
thermal driver is resolution of this discussion about thermal zones.
Can we kindly resolve this soon so we have a chance to land it in v4.6.

I think the problem is, that Eduardo wants to see the hierachical thermal
zones being used. But there is still a discussion ongoing [1].
It seems the original Author lost interest in the hierarchical thermal
zones. I am not convinced that we need hierarchical thermal zones for
the Mediatek driver since from the five sensors we only need the maximum
temperature (If this ever changes we could still rework it).

Given the current speed of communication I am not willing to add
another, possibly controversal, dependency to an otherwise simple
driver. I am even less willing when concerns like these come after *v12*
of this series.

Eduardo, it would really help to get a word from you.
Apologize for the long delays here. In fact I want the hierarchical
support on this driver. But given that it is not really a strong
dependency and the hierarchical support is still an ongoing development,
I don't see why we should not merge this driver.

I also have had the chance to try it out in a board, and seams to work
for me. I am adding to my tree.

Thanks for the perseverance. :-)
Sascha
