rtc: ds1307: add temperature sensor support for ds3231
DS3231 has the temperature registers with a resolution of 0.25 degree celsius. This enables to get the value through hwmon. # cat /sys/class/i2c-adapter/i2c-2/2-0068/hwmon/hwmon0/temp1_input 21000 Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Acked-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
