The original Qualcomm APQ8060 Dragonboard. I'm mainlining it as a test
target right now, mostly for GPIO work:
http://dflund.se/~triad/krad/dragonboard/dragonboard.jpg

It has the following on I2C on a special sensor board (totally undocumented
and no real mention in even the source code in the BSP for the board for
some of them, I guess they never got around to enable some of them):

- Kiorin KXSD9 accelerometer - this culprit

- Bosch BM085 pressure sensor/altimeter - works flawlessly with upstream
driver and a few patches (just sent).

- Capella CM3605 proximity and ambient light sensor (same as used on the
original Nexus One, yay) this require you to turn on a special IR LED for
the proximity sensor to work (!)

- AK8975 Compass/Magnetometer - just works nicely with the upstream
driver and a minor patch for an extra regulator

- Invensense MPU3050 Gyroscope
drivers/input/misc/mpu3050.c
Thinking about just moving this driver across if it's working as a starting
point, like I did with the BH1780 driver. Is this one of those who would need
a IIO <-> input bridge if we migrate it?
