[PATCH 0/4] arm: dts: am57xx: Correct the thermal thresholds

[Keerthy]

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:

[PATCH 1/4] ARM: dts: am57xx: Introduce commercial grade thermal thresholds

[Keerthy]

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

[PATCH 2/4] ARM: dts: am57xx: Introduce industrial grade thermal thresholds

[Keerthy]

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

[PATCH 3/4] ARM: dts: am57xx-beagle-x15: Include the commercial grade thresholds

[Keerthy]

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

[PATCH 4/4] ARM: dts: am57xx-idk: Include Industrial grade thermal thresholds

[Keerthy]

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