Hello all,
Now that the basic thermal DT support is merged into Rui's tree,
I am resending this series, which introduces the DT node entries
for DRA7 thermal limits representation.
The series adds two thermal zones, to represent IVA and DSPEVE,
respectively. It also adds the support to tmp102 and a corresponding
pcb thermal zone.
There are only cosmetic changes from v1. A couple of spaces and tabulations
have been fixed, and minor changes in sentences present in commit log.
One difference from V1 is the fact that now bandgap is introduced under
OCP, which is also a minor diff.
This patch series has been runtime tested on DRA7-evm.
All best
Eduardo Valentin (7):
arm: dts: add dra7 DSPEVE thermal data
arm: dts: add dra7 IVA thermal data
arm: dts: dra7: add bandgap entry
arm: dts: add cooling properties on dra7 cpu node
arm: dts: dra7: add thermal data
arm: dts: add tmp102 i2c sensor node on dra7-evm
arm: dts: add thermal zones info on tmp102 for DRA7-EVM

This patch introduces a dtsi file to contain the thermal data
for DSPEVE domain on DRA7 and later SoCs. This data will
enable a thermal shutdown at 125C.

DRA7 devices can reach high temperatures and thus
needs to have cpufreq-cooling on systems running on it.
This patch adds the required cooling device properties
so that cpufreq-cpu0 driver loads the cooling device.

This patch adds thermal data for DRA7 SoCs. Cpufreq cooling
will be enabled for MPU domain whenever it crosses 100C.
GPU, CORE, DSPEVE, IVA will be exposed and system shall

I'm okay with this patch set. But as long as this patch set does not
change any code under drivers/thermal/, I prefer these patches to go to
your thermal-soc tree first.
