When each new model appears, users need to adjust again. Testing this requires the rebuild of kernel, thus it's not trivial for end-users. This patch adds a module parameter "axes" to allow a custom axis-mapping without patching and recompiling the kernel driver. User can pass the parameter such as axes=3,2,1. Also it can be changed via sysfs.
