From ef7fcdaebfce56bd7f1ac3b916b5d587a3666f10 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 14 Apr 2017 20:32:53 +0200 Subject: [PATCH] power: supply: max17042_battery: Add support for the TECHNOLOGY attribute The max17042 is intended for Li-Ion or Li-Po batteries, add a TECHNOLOGY attribute to reflect this. Note this is hardcoded to Li-Ion as there is no way to tell the difference, and Lithium-Ion Polymer batteries are a sub-family of Lithium-Ion so Li-Ion technically is correct for both. Using Li-Ion for both is already done by many drivers and is much better then not providing any technology info at all.
