[PATCHv4 10/18] arm: dts: add omap4 CPU thermal data

[Eduardo Valentin]

This patch changes a dtsi file to contain the thermal data
for MPU domain on OMAP4 and later SoCs. This data will
enable the passive cooling with CPUfreq cooling device
at 100C and the system will do a thermal shutdown at 125C.

This thermal data can be reused across TI SoC devices.

we might want to move bandgap under ocp?

Yes, agreed. But I don't think this change is related to this patch or
to this series.

Correct - this comment is not related to the current patch, hence my 2
cents ;) - will be nice to have it cleaned up though..

[PATCHv4 13/18] arm: dts: add cooling properties on omap4430 cpu node

[Eduardo Valentin]

OMAP4430 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.

[PATCHv4 15/18] arm: dts: add omap5 GPU thermal data

[Eduardo Valentin]

This patch changes a dtsi file to contain the thermal data
for GPU domain on OMAP5 and later SoCs. This data will
enable a thermal shutdown at 125C.

This thermal data can be reused across TI SoC devices.

[PATCHv4 16/18] arm: dts: add omap5 CORE thermal data

[Eduardo Valentin]

This patch changes a dtsi file to contain the thermal data
for CORE domain on OMAP5 and later SoCs. This data will
enable a thermal shutdown at 125C.

This thermal data can be reused across TI SoC devices.

[PATCHv4 17/18] arm: dts: add omap5 thermal data

[Eduardo Valentin]

This patch changes the dtsi entry on omap5 to contain
the thermal data. This data will enable the passive
cooling with CPUfreq cooling device at 100C. The
system will do a thermal shutdown at 125C whenever
any of its sensors sees this level.

[PATCHv4 18/18] arm: dts: add cooling properties on omap5 cpu node

[Eduardo Valentin]

OMAP5 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.
