From cfa3b24c38b58cb6acabe6441b4668e530e957af Mon Sep 17 00:00:00 2001 From: Kalhan Trisal Date: Mon, 9 Aug 2010 17:21:05 -0700 Subject: hmc6352: add driver for the HMC6352 compass This driver will report the heading values in degrees to the sysfs interface. The values returned are headings . e.g. 245.6 Alan: Cleanups requested now all folded in and a sysfs description to keep Andrew happy. The sysfs description now resembles hwmon.
