arm: dts: am57xx: Correct the thermal thresholds

Noticed that earlier post had a wrong list name hence resending the series.

Currently all the am57xx versions are wrongly re-using the dra7 thermal threholds. Introduing the correct thermal thresholds based on industrial or commercial grade silicon present on the individual boards.

Tested on AM57XX-BEAGLE-X15 (Commercial) and AM572X-IDK(Industrial) for the trip_point node sysfs temperatures.

These patches are on top of:

1.9.1

The silicon versions which are non ES2.0 are commercial grade silicon and have lower thermal thresholds.

The silicon version ES2.0 onwards are industrial grade samples and have higher thermal thresholds than commecial grade samples.

am57xx-beagle-x15 have commercial grade samples whose thermal thresholds lower than dra7. Hence correcting the same.

am57xx-idk have Industrial grade samples whose thermal thresholds are different as compared with dra7. Hence correcting the same.

Tony,

A Gentle ping on this series.

Hi,

I already have these in Linux next for v4.7 merge window:

5b6042237dc8 ("ARM: dts: am57xx-idk: Include Industrial grade thermal thresholds") 266e62f97539 ("ARM: dts: am57xx-beagle-x15: Include the commercial grade thresholds") cf9b7d5e9cfd ("ARM: dts: am57xx: Introduce industrial grade thermal thresholds") 286db0a516e0 ("ARM: dts: am57xx: Introduce commercial grade thermal thresholds")

Care to check if those are OK? If fixes are needed, please post an incremental patch against current Linux next.

Regards,

Tony

Thanks Tony. Those 4 commits are fine.

Regards,
Keerthy
