we will have AM57xx-IDK as well coming down the line. we already have
arch/arm/boot/dts/am57xx-cl-som-am57x.dts
arch/arm/boot/dts/am57xx-sbc-am57x.dts - not really sure what grade of
silicon are used in cl-SOM and sbc boards.

This data is in the AM572x datasheet:
http://www.ti.com/lit/ds/symlink/am5728.pdf

Table 5-3 in the current version contains the maximum junction
temperatures.

this indicates that there are "Commercial" and "extended" -> we may
need to introduce just 2 dtsis -> am57xx-commercial and
am57xx-extended and reuse those based on the part on the board. just a
suggestion..
