This patch provides driver for two sw compatible 3 axis magnetometer chips (AMI305 / AK8974). Driver provides coordinates as polled input device. Chip can provide interrupt when the measurement result is ready, but this feature is not used. Instead, new measurement is started at polling event frequency. This method allows more flexible measurement interval. Activity level at kernel side is about the same in both interrupt and polling based methods. Furhtermore, this eliminate need to use interrupt line at HW level. Chip is powered on when the polled device is opened and powered down when the device is closed. Axes can be remapped via platform data. sysfs interface: selftest - Perform chip specific selftest as specified by manufacturer active - returns chip power state: ON or OFF fuzz - adjust input system "fuzziness" parameter Patch is applicable to Dmitry Torokhov's input tree - next branch. This tree was selected since patch requires a change to polled input device which is allready in that tree (open / close methods).
