[PATCH 0/9] thermal: rockchip: Support rk3366/rk3399 SoCS and fixes the driver

[Caesar Wang]

Hello Eduardo, Heiko
This series pacthes to support the rk3366/rk3399 SoCs thermal, and fixes the driver.

65ae684 thermal: rockchip: disable thermal->clk in err case
31e6d69 thermal: rockchip: fixes the code_to_temp for tsadc driver
6e2d6fb thermal: rockchip: update the tsadc table for rk3399
49f6ccf thermal: rockchip: handle the power sequence for tsadc controller
9f8bd52 thermal: rockchip: Support RK3366 SoCs in the thermal driver
a959e42 thermal: rockchip: add the notes for better reading
e5cbc6a thermal: of: Add support for hardware-tracked trip points
7f613e4 thermal: rockchip: add the set_trips function
94cc571 arm64: dts: rockchip: move the rk3368 thermal data into rk3368.dtsi

Verified on url =
https://github.com/Caesar-github/rockchip/commits/wip/fixes-rockchip-thermal-20160418
Based on linux-next kernel for 20160415

Verified on rk3288/rk3366/rk3399 SoCs with rockchip inside kernel(develop4.4).

The rk3399 dtsi has benn sent on https://patchwork.kernel.org/patch/8462441/.
The dts thermal will be updated in later.

[PATCH 9/9] arm64: dts: rockchip: move the rk3368 thermal data into rk3368.dtsi

[Caesar Wang]

In order to be standard to manage for rockchip SoCs,  move the thermal
data into rk3368 dtsi, we needn't to add a new file for thermal.

Fixes commit f990238f859e
("arm64: dts: rockchip: Add main thermal info to rk3368.dtsi")

I'm pondering this change for some days now and am still undecided :-) 
On the one hand you're right ... this doesn't need to be its own file on the 
other hand it creates churn, but I'm inclined to pick it up.

Can you at least provide another patch doing the same for rk3288, so that we 
really standardize on one form for Rockchip SoCs?


Thanks
Heiko

Applied patches 1-6. But please, consider sending a patch to use
usleep_range.

These patches, though, will need further discussion. I believe you would
probaly refresh them once we agree on Sascha's patchset.
