From 00cda13e339c9f4956a6f036675df2ca5b5a552e Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Fri, 14 Aug 2020 00:34:02 +0300 Subject: power: supply: Support battery temperature device-tree properties The generic battery temperature properties are already supported by the power-supply core. Let's support parsing of the common battery temperature properties from a device-tree.
