The specification can be downloaded from: http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-04.pdf. The chip contains both an accelerometer and a magnetometer. This patch adds support only for the magnetometer part. The temperature compensation formulas are based on bmm050_api.c authored by contact@bosch.sensortec.com.

Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

In functionality is resembles AK8975 or AK8963. But there are several differences, so instead of modifying existing AK8975 driver and keep it clean, implemented as a separate driver. The key differences are: - Register map is different and have different indexes - AK09911 is a very compact interface with no DRDY pin. So no support of interrupt or GPIO poll - Even for polled mode no mention on ST2 register, which is required in ak8975 driver - mode values are different for fuse access Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org> 2014-03-22T12:41:37+00:00 Srinivas Pandruvada srinivas.pandruvada@linux.intel.com 2014-03-19T16:56:00+00:00 urn:sha1:6027c077f62f11818a7645151119f8718862d764 AK8963 and AK8975 use same register definitions, except the range of X,Y,Z values. Added support of 8963 based on i2c_device_id. Unfortunately there is no way to detect the type via registers, both device registers return 0x48 as id of chipset.
