From 9066073c6c27994a30187abf3b674770b4088348 Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Thu, 5 May 2016 14:21:39 +0530 Subject: thermal: qcom: tsens: Add a skeletal TSENS drivers TSENS is Qualcomms' thermal temperature sensor device. It supports reading temperatures from multiple thermal sensors present on various QCOM SoCs. Calibration data is generally read from a non-volatile memory (eeprom) device. Add a skeleton driver with all the necessary abstractions so a variety of qcom device families which support TSENS can add driver extensions. Also add the required device tree bindings which can be used to describe the TSENS device in DT.
