[PATCH 2/2] arm64: dts: ti: Add k3-am62-pocketbeagle2

[Robert Nelson <robertcnelson@gmail.com>]

BeagleBoard.org PocketBeagle 2 is an upgraded version of the popular
PocketBeagle.  It is based on Texas Instruments AM6232 SoC. Its dual
A53 cores can provide higher performance than classic PocketBeagle.
The new design comes with pre-soldered headers, a 3-pin JST-SH 1.00mm
UART debug port, a USB-C port, Texas Instruments MSPM0L1105 Cortex-M0+
MCU for ADC, 512MB RAM, and a LiPo Battery charger.
