Hello Eduardo, Heiko, Michael & Stephen:

This series pacthes to support the rk3228 SoCs thermal.

They have the following patches to work on rk3228 SoCs.

bdc79c0 ARM: dts: rockchip: add the thermal main info found on rk3228
22ea3c3 ARM: dts: rockchip: enable the tsadc for rk3228 evb
b907b75 thermal: rockchip: fix the tsadc sequence output on rk3228/rk3399
fb11fbd thermal: rockchip: the rename compatibles for rockchip SoCs
df9c1bd thermal: rockchip: fix calculation error for code_to_temp
bd2720c thermal: rockchip: fix a impossible condition caused by the warning
8cf2d1b clk: rockchip: add the tsadc clocks found on rk3228 SoCs
1a6f334 clk: rockchip: add id of the tsadc clock found on rk3228 SoCs

Verified on https://github.com/Caesar-github/rockchip/tree/rk3228-thermal-tests.
This series patches are based on
Linux version 4.5.0-rc1+ (wxt@ubuntu) (...) #186 SMP Tue Feb 2 17:11:48 CST 2016

Hi Michael,Stephen
PATCH[1/8-2/8]:
Add the tsadc needed clocks for rk3228 SoCs

Hi Eduardo,
PATCH[3/8]:
To fix a build warning came from Dan Carpenter report smatch check,
Thanks.
As the patch exists in https://patchwork.kernel.org/patch/7757311/

PATCH[4/8]:
fix calculation error for code_to_temp
That's a error since the copy causes.

PATCH[5/8]:
the rename compatibles for rockchip SoCs
As the more and more rockchip SOCs are supported in thermal driver. this pacth
supposed to be compatible for better.

PATCH[6/8]:
fix the tsadc sequence output on rk3228/rk3399
Fixes the tsadc sequence output since the rk3228/rk3399 SoCs design.

Hi Heiko,
PATCH[7/8-8/8]: thermal DTS
1) add the thermal main info found on rk3228
2) enable the tsadc for rk3228 evb

I'd appreciate if someone have free time to review that. :)

As the Dan report the smatch check the thermal driver warning:
drivers/thermal/rockchip_thermal.c:551 rockchip_configure_from_dt()
warn: impossible condition '(thermal->tshut_temp > ((~0 >> 1))) =>
(s32min-s32max > s32max)'

Although The shut_temp read from DT is u32,the temperature is currently
represented as int not long in the thermal driver.
Let's change to make shut_temp instead of the thermal->tshut_temp for
the condition.

Fixes: commit 437df2172e8d
("thermal: rockchip: consistently use int for temperatures")

the calculation use a global table, not their own table.
so adapt the table to the correct one.

SoCs are supported in thermal driver.

As the TRM says, add the tsadc_q_sel to control the temperature-code
sequence since the rk3228/rk3399 need set this bit (1024 - tsadc_q)
as output.
