From e9450436c2448e59dc3d24adb94d8ad9945584c8 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 9 Jan 2014 10:01:05 -0800 Subject: [PATCH] chrome ec: Fix temperature calcualtion in PATx methods The PATx methods will be passed a temperature in deci-kelvin, so it needs to be converted back to kelvin before being sent to the EC. The PAT disable method is changed to take the temperature ID as an argument so individual sensors can be disabled. BUG=chrome-os-partner:17279 BRANCH=rambi TEST=build and boot on rambi, load esif_lf kernel drivers and esif_uf userspace application. Start and stop DPTF and see that temperature thresholds are set to sane values.
