-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
