From 771151bed994850c9afe48a8c8400d6aad33071a Mon Sep 17 00:00:00 2001 From: Yangtao Li Date: Fri, 24 Jul 2020 15:11:42 +0800 Subject: thermal: sun8i: add TEMP_CALIB_MASK for calibration data in sun50i_h6_ths_calibrate For sun50i_h6_ths_calibrate(), the data read from nvmem needs a round of calculation. On the other hand, the newer SOC may store other data in the space other than 12bit sensor data. Add mask operation to read data to avoid conversion error.
