ARM: dts: am437x: cm-t43: add basic support for sbc-t43 Add basic support for SBC-T43: a CM-T43 based single board computer. CM-T43 is an AM437x based System-on-Module designed to serve as a building block in embedded applications. SBC-T43 is composed of CM-T43 module on top of the SB-SOM-T43 baseboard. Basic support includes UART, GPIO, and I2C.
