arm64: dts: ti: Add support for AM62A7-SK
AM62A StarterKit (SK) board is a low cost, small form factor board designed for TI’s AM62A7 SoC. It supports the following interfaces: * 2 GB LPDDR4 RAM * x1 Gigabit Ethernet interface * x1 HDMI Port with audio * x1 Headphone Jack * x1 USB2.0 Hub with two Type A host and x1 USB Type-C DRP Port * x1 UHS-1 capable µSD card slot * M.2 SDIO Wifi + UART slot * 1Gb OSPI NAND flash * x4 UART through UART-USB bridge * XDS110 for onboard JTAG debug using USB * Temperature sensors, user push buttons and LEDs * 40-pin User Expansion Connector * 24-pin header for peripherals in MCU island (I2C, UART, SPI, IO) * 20-pin header for Programmable Realtime Unit (PRU) IO pins * 40-pin CSI header Add basic support for AM62A7-SK.
