This patch adds the support for Exynos5433's TMU (Thermal Management Unit). Exynos5433 has a little different register bit fields as following description: - Support the eight trip points for rising/falling interrupt by using two registers - Read the calibration type (1-point or 2-point) and sensor id from TRIMINFO register - Use a little different register address Cc: Zhang Rui <rui.zhang@intel.com> Cc: Eduardo Valentin <edubezval@gmail.com> Cc: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
