iio: add mcp4725 I2C DAC driver
v5: * fix warnings (Jonathan Cameron) v4: * remove unused indio_dev pointer in mcp4725_data (Jonathan Cameron) * use u16 instead of unsigned short in mcp4725_data (Jonathan Cameron) * #include mcp4725.h from linux/iio/dac/ v3: * move from staging to drivers/iio * switch to chan_spec * dev_get_drvdata() -> dev_to_iio_dev() * annotate probe() and remove() with __devinit and __devexit v2 (based on comments from Jonathan Cameron and Lars-Peter Clausen): * did NOT switch to chan_spec yet * rebase to staging-next tree, update iio header locations * dropped dac.h #include, not needed * strict_strtol() -> kstrtol() * call iio_device_unregister() in remove() * everything in one patch Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
