Hi,
BeagleBoard.org BeagleBadge[1] is a compact, affordable open source
hardware [2] single board computer based on the Texas Instruments AM62L3
SoC designed for IoT and embedded applications. Add base support for
the same.
Bootlog: https://gist.github.com/jmenti/d85f17bf5264f1364866df91e60231eb
This patch series adds:
- Device tree bindings update for am62l3-badge
- Device tree source for BeagleBadge board

No pinmux here? Even if you are using the default muxing, you should still add
the pinmux info for both completness and to prevent accidental pin reuse by
some future addition. Same for EPWM above and USB nodes below.

Scanning over the bootlog it looks like the VTM driver is active but
we're missing the thermal-zones{} node which is causing it issues.
