staging:iio:hmc5843: Add support for spi hmc5983 2014-07-23T20:48:24+00:00 Josef Gajdusek atx@atalax.net 2014-07-22T15:03:00+00:00 d3f1621960223799b19bca9b503c333a3833d7f7 This patch adds support for the hmc5983 spi interface. This chip is almost identical to the hmc5883. The difference being added temperature compensation, additional available sample rate (220Hz) and an SPI interface.
