From 20f0af759d79c53a818da5c953874c9e801f726a Mon Sep 17 00:00:00 2001 From: Caesar Wang Date: Mon, 9 Nov 2015 12:48:59 +0800 Subject: [PATCH] thermal: rockchip: Support the RK3368 SoCs in thermal driver The RK3368 SoCs support to 2 channel TS-ADC, the temperature criteria of each channel can be configurable. The system has two Temperature Sensors, channel 0 is for CPU, and channel 1 is for GPU.
