Support for the Mikrotik Groove 52HPn. GPIO 17 appears to be the
buzzer. GPIO 14 is a test point to the right of the ethernet port.
Everything works except UART, I can receive output from the groove but
when i try to transmit keystrokes it seems to struggle on receiving
them. I'm guessing there is another driver attempting to use the UART
pins? Perhaps they need to be disabled to get proper UART usage? I'm
also not sure how to unlock the bottom 2 LED's from the hardware. It
appears that the second to last LED is ethernet link, and the last LED
is ethernet netdev. Everything else seems to work networking,
wireless, etc.
