The Polaroid MID2407PXE03 is an a23 based 7" tablet based on a M86_MB V2.0 PCB, featuring a 800x480 LCD, 512MB RAM, 4G NAND, esp8089 wifi, gsl1680 touchschreen, micro-sd slot, 3.5mm headphone jack and a micro-usb otg connector which doubles as charging port.

The dts file is identical to the one submitted to the upstream kernel.
