From 6c87eb21aa0b3b58001852601f130db1f8237de7 Mon Sep 17 00:00:00 2001 From: Caesar Wang Date: Thu, 5 Jan 2017 12:37:55 +0800 Subject: [PATCH] thermal: rockchip: fixes the conversion table As Ayaka reported the thermal was abormal on rk3288 at booting time. thermal thermal_zone1: critical temperature reached(125 C),shutting down thermal thermal_zone2: critical temperature reached(125 C),shutting down thermal thermal_zone1: critical temperature reached(125 C),shutting down thermal thermal_zone2: critical temperature reached(125 C),shutting down ... The root caused by reading the invald analogic value, the value is zero will convert the 125 degree to trigger the critical temperature. Fixes it with insteading of the incorrect reading now.
