We've been seeing some crashes at reboot test on rk3288-based systems,
which boards have not reset pin connected to NPOR, they reboot by
setting 0xfdb9 to RK3288_GLB_SRST_FST register. If the APLL works in
a high frequency mode, some IPs might hang during soft reset.
It appears that we can fix the problem by switching to slow mode before
reboot, just like what we did before suspend.

For InnoSilicon usb2.0 phy, there is no siddq bit for operating,
what is more, when we control usb phy to suspend, its Plls will
not be affected. So we can operate resume/suspend bits directly
when it is going to power on/off.

This patch enables the tsadc for rk3399 evb board.
The rk3399 evb board uses the gpio to reset the chip since it connects the
PMIC to work, and TSHUT is low active on evb board.

This patch adds the thermal needed main information for rk3399 SoCS.
Basically has the following content:
1) TSADC controller:
Add the needed attributes for rk3399 TSADC controller.
Especially for the TSHUT, in some cases if we are unable to shut it down
in orderly fashion (says: kernel is stuck holding a lock or similar), then
hardware TSHUT will reset it.
If the temperature is over 95C over a period of time the thermal shutdown
of the tsadc is invoked with can either reset the entire chip via the CRU,
or notify the PMIC via a GPIO. This should be set in the specific board.
2) Thermal zones:
Add the needed device mode for thermal generic framework.
Detail in Documentation/devicetree/bindings/thermal/thermal.txt.

Rockchip_spi_set_cs could be called by spi_setup, but
spi_setup may be called by device driver after runtime suspend.
Then the spi clock is closed, rockchip_spi_set_cs may access the
spi registers, which causes cpu block in some socs.

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.
