From dc92cd0c13e0dbe2201fdececbb43c74af05da70 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sat, 12 May 2012 11:33:11 -0700 Subject: hwmon: (ina2xx) Add support for INA220 and INA230 INA220 is register compatible to INA219, and INA230 is register compatible to INA226, so all we need to do is to add name aliases for those two chips.
