Mauro Carvalho Chehab	1f234ff	2019-04-17 06:46:26 -0300	[diff] [blame]	208	- LTC2974 and LTC2975 are quad digital power supply managers.
				209	- LTC2978 is an octal power supply monitor.
				210	- LTC2977 is a pin compatible replacement for LTC2978.
				211	- LTC2980 is a 16-channel Power System Manager, consisting of two LTC2977

				226	-----------
				227
				228	This driver does not probe for PMBus devices. You will have to instantiate
				229	devices explicitly.
