It will cause whitespace warnings when applying and will also cause issues applying other changes at the end of the file if they rely on the extra line. And check the whole series, thanks :) It will make my life a bit easier. And the Subject line should start with "ARM: dts: ..." for the unified look.

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.
