Subject: [PATCH 3/3] arm64: dts: ti: Add support for AM62D2-EVM
AM62D EVM evaluation module (EVM) is a low-cost expandable platform board
designed for TI’s AM62D2 SoC. It supports the following interfaces:
* 4 GB LPDDR4 RAM
* x2 Gigabit Ethernet expansion connectors
* x4 3.5mm TRS Audio Jack Line In
* x4 3.5mm TRS Audio Jack Line Out
* x2 Audio expansion connectors
* x1 Type-A USB 2.0, x1 Type-C dual-role device (DRD) USB 2.0
* x1 UHS-1 capable µSD card slot
* 32 GB eMMC Flash
* 512 Mb OSPI NOR flash
* x4 UARTs via USB 2.0-B
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs
Add basic support for AM62D2-EVM.
