+Description
+-----------
+
+- LTC2974 and LTC2975 are quad digital power supply managers.
+- LTC2978 is an octal power supply monitor.
+- LTC2977 is a pin compatible replacement for LTC2978.
+- LTC2980 is a 16-channel Power System Manager, consisting of two LTC2977
+- in a single die. The chip is instantiated and reported as two separate chips
+- on two different I2C bus addresses.
+- LTC3880, LTC3882, LTC3886, and LTC3887 are dual output poly-phase step-down
+- DC/DC controllers.
+- LTC3883 is a single phase step-down DC/DC controller.
+- LTM2987 is a 16-channel Power System Manager with two LTC2977 plus
+- additional components on a single die. The chip is instantiated and reported
+- as two separate chips on two different I2C bus addresses.
+- LTM4675 is a dual 9A or single 18A μModule regulator
+- LTM4676 is a dual 13A or single 26A uModule regulator.
+- LTM4686 is a dual 10A or single 20A uModule regulator.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.
+
+Example: the following commands will load the driver for an LTC2978 at address
+0x60 on I2C bus #1::
+
+	# modprobe ltc2978
+	# echo ltc2978 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
