At the end of the transfer, the 11-bit 2's +complement digital temperature (sent via the SIO line), is available in the +driver for interpretation. This driver makes use of the kernel's in-core +SPI support. + +Thanks to +--------- +Jean Delvare <khali@linux-fr.org> for mentoring the hwmon-side driver +development. |
