updated itg3200 proposal
macros to print vars with values during compile time
working on aspirin1 driver
aspirin1 cleanup, seems to work fine so far...
[imu] navgo: ImuEvent as static inline instead of macro
[conf][i2c] changed all FOO_I2C_DEVICE defines to FOO_I2C_DEV to be consistent
While FOO_I2C_DEVICE is less ambiguous, FOO_I2C_DEV was choosen since most modules already use that.
Since this is a user facing config, rather keep existing configs working...
renamed some asprin config options
some more refactoring for hmc58xx and itg3200
aspirin driver seems to work without arch depedent eoc/irq handling, ready for next step
