[PATCH v2 0/9] Better compatible for the rockchip thermal and support RK3368 SoCs

[PATCH v2 0/9] Better compatible for the rockchip thermal and support RK3368 SoCs

[Caesar Wang]

This series patchs are working for RK3368 on Rockchip platform.

@Heiko,
    The PATCH [5/6] is working based on big/littel cluster cpufreq
    added. Anyway, the PATCH [5/6] also work for next kernel.

@Eduardo,
This patchset are based on linus master branch.
Note: Need add the following thermal patchs for thermal driver before apply
this series patchs.

1) thermal: rockchip: fix handling of invalid readings
(https://patchwork.kernel.org/patch/6973101/)

2) thermal: rockhip: fix setting thermal shutdown polarity
(https://patchwork.kernel.org/patch/6973131/)

3) dt-bindings: rockchip-thermal: Add the pinctrl states in this document
(https://patchwork.kernel.org/patch/7472021/)

4) thermal: rockchip: support the sleep pinctrl state to avoid glitches in s2r
(https://patchwork.kernel.org/patch/7472051/)

I'm glad these patchs have merged in thermal-soc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal.git

Changes in v2:
- As Eduardo comments on patch v1, split in smaller changes.
- make the conversion table in as a parameter both code_to_temp
  and temp_to_code function.
Series-changes: 1
- As Dmitry comment, make the conversion table in as a parameter.
- remove some unused, completed on other patchs.
- fix a copy wrong name.
Series-changes: 1
- support the opt gpio pinctrl state

Changes in v1:
- %s/thermal/rockchip-thermal in subject.
- add a new patch for thermal driver to support more SoCs.

[PATCH v2 7/9] arm64: dts: Add the thermal data found on RK3368

[Caesar Wang]

This patchset add the thermal for RK3368 dts,
Since the two CPU clusters, with four CPU core for each cluster,
One cluster is optimized for high-performance(big cluster) and the othe
is optimized for low power(little cluster).

This patch adds the second order for thermal throttle, and the critical
temperature for thermal over-tempeature protection on Software.

[PATCH v2 9/9] arm64: dts: Enable the Thermal on R88 board

[Caesar Wang]

This patch enable the TS-ADC.

When a thermal temperature is invoked use the CRU to reset the chip
on R88 board. TSHUT is low active on this board.

Yeah, apologize the delay on giving you a feedback on your code. As I
mentioned before, I had a couple of other things in past weeks that
consumed my time. 

Anyways, this specific patch series looks way better now that you have
split it further. I will have a better look on it again and let you
know when it will land.

I call dibs on the devicetree patches :-) .

Code and dt parts are very much separate, so I'd like to take the dt parts 
though my tree and arm-soc to keep further dts changes together.
Of course only once you are ok with the code parts :-)

Devicetree parts themselfs look ok to me.

I am picking 1-3 for now. Device tree part looks OK to me too.

Many thanks, I guess that I don't need send the dts patch again.;-)
the Code is still a bit change for thermal driver.

I think you should still send the dts patches with next revisions. I can
only take the patches, once Eduardo is satisfied with the code changes
that include the new binding, and while I hope that this will be in v3, it
will be hard if we get to v5 or so, to grep through the older revisions,
trying to find the dts changes :-).
