-Subject: hwmon: (lm70) Add ti,tmp125 support
-
-The TMP125 is a 2 degree Celsius accurate Digital
-Temperature Sensor with a SPI interface.
-
-The temperature register is a 16-bit, read-only register.
-The MSB (Bit 15) is a leading zero and never set. Bits 14
-to 5 are the 1+9 temperature data bits in a two's
-complement format. Bits 4 to 0 are useless copies of
-Bit 5 value and therefore ignored.
