From: Zhang Rui Date: Mon, 13 May 2019 17:58:54 +0000 (-0400) Subject: hwmon/coretemp: Support multi-die/package X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cfcd82e632882372db960b50782a439a8ba56c09;p=openwrt%2Fstaging%2Fblogic.git hwmon/coretemp: Support multi-die/package Package temperature sensors are actually implemented in hardware per-die. Update coretemp to be "die-aware", so it can expose mulitple sensors per package, instead of just one. No change to single-die/package systems.
