arm64: dts: ti: Add support for AM642 SK
AM642 StarterKit (SK) board is a low cost, small form factor board designed for TI’s AM642 SoC. It supports the following interfaces: * 2 GB LPDDR4 RAM * x2 Gigabit Ethernet interfaces capable of working in switch and MAC mode * x1 USB 3.0 Type-A port * x1 UHS-1 capable µSD card slot * 2.4/5 GHz WLAN + Bluetooth 4.2 through WL1837 * 512 Mbit OSPI flash * x2 UART through UART-USB bridge * XDS110 for onboard JTAG debug using USB * Temperature sensors, user push buttons and LEDs * 40-pin Raspberry Pi compatible GPIO header * 24-pin header for peripherals in MCU island (I2C, UART, SPI, IO) * 54-pin header for Programmable Realtime Unit (PRU) IO pins * Interface for remote automation. Includes: * power measurement and reset control * boot mode change Add basic support for AM642 SK.
