arm64: dts: ti: add verdin am62
This patch adds the device tree to support Toradex Verdin AM62 a computer on module which can be used on different carrier boards and the Toradex Verdin Development Board carrier board. The module consists of an TI AM62 family SoC (either AM623 or AM625), a TPS65219 PMIC, a Gigabit Ethernet PHY, 512MB to 2GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC, an I2C EEPROM, an RX8130 RTC, and optional Parallel RGB to MIPI DSI bridge plus an optional Bluetooth/Wi-Fi module. Anything that is not self-contained on the module is disabled by default. So far there is no display nor USB role switch supported, apart of that all the other functionalities are fine.
