+- check that UART connectivity is okay (levels and such)
+- check control signals (power on/off, reset, interrupt, etc.)
+- check battery connection (voltage, current)
+- height will interfere with WLAN daughterboard

+Use codec to detect jack insertion and HOLD button
+
+
+The Wolfson WM8753L has the ability to detect jack insertion and pressing
+the HOLD button (MIC bias short-circuit).
+
+Rough outline:
+- HOLD seems to be internal, ok
+- route JACK_INSERT to the codec (GPIO4), not the CPU
+- route codec IRQ (GP1) to CPU
+
+Q: how do we distinguish multiple interrupt sources ? Mask and see if
+the interrupt persists ? Or would we have to upgrade to a 3-wire interface
+so that we could read data back ? (Seems too intrusive.)
