iio: ak8975: Fix calculation formula for convert micro tesla to gauss unit 2014-02-08T10:28:05+00:00 Beomho Seo beomho.seo@samsung.com 2014-04-02T08:15:00+00:00 bef44abccb2677e8d16e50b75316d4fd1061be81 This effects the reported scale of the raw values, and thus userspace applications that use this value. One micro tesla equal 0.01 gauss. So I have fixed calculation formula And add RAW_TO_GAUSS macro. ASA is in the range of 0 to 255. If multiply 0.003, calculation result(in_magn_[*]_scale) is always 0. So multiply 3000 and return and IIO_VAL_INT_PLUS_MICRO. As a result, read_raw call back function return accurate scale value.
