nit: there is whitespace damage (space before tab) on the line before
this one.  It's more obvious in the patch you uploaded to gerrit which
highlights this in red:

https://chromium-review.googlesource.com/#/c/213967/5/Documentation/devicetree/bindings/thermal/rockchip-thermal.txt

Did you run your patches through checkpatch before submitting?

FWIW vim users like me can put the following in their .vimrc file to
have whitespace damage visible right away:

:highlight RedundantSpaces ctermbg=red guibg=red
:match RedundantSpaces /\s\+$\| \+\ze\t/

Thanks.

Hi Caesar,

is there any reason to not use the existing thermal bindings? You can
find a description in
Documentation/devicetree/bindings/thermal/thermal.txt and example code
in omap, or in the patches for Tegra recently posted by Mikko
Perttunen.

Regards,

Tomeu

Why should I use the existing thermal bindings?
I believe omap,tegar and rockchip are  the three seperate thermals driver.

So far, I submitted the series Patchs for rockchip thermal.

Because otherwise, you are asking to merge duplicated code. There's a
generic way to define thermal zones, trip points, cooling devices,
etc. And also code to parse and plug them together. Why add
soc-specific code to do the same?

> I believe omap,tegar and rockchip are  the three seperate thermals driver.

Yes, and OMAP is already using the generic bindings, and the proposed
patches for Tegra as well, and I think it would make sense for
Rockchip to also use them (unless I'm missing something).

Tomeu

You are talking about drivers/thermal/of-thermal.c, right? Yes, I think
Rockchip should be using the same generic framework if possible.

Thanks.
