From f7a228eaf4f8aa54c223a763d80bed5dcb072499 Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Thu, 18 Apr 2019 16:46:50 +0200 Subject: [PATCH] power: supply: olpc_battery: Use DT to get battery version Avoid using the x86 OLPC platform specific call to get the board version. That wouldn't work on FDT-based ARM MMP2 platform. Add the XO 1.5 compatible string too. This is actually not completely necessary as the battery nodes on XO 1.5 claim to be compatible with "olpc,xo1-battery", but there are, in fact, differencies.
