Temperature sensor generates electrical analog voltage from temperature of each chain. The analog voltage is converted to digital value through ADC. For reading temperature values fom user space, hw monitoring device is used. Whenever the user requests for current temperature, the driver sends WMI command and wait for response. For reading temperature, cat /sys/class/ieee80211/phy*/device/hwmon/hwmon2/temp1_input Signed-off-by: Pradeep Kumar Chitrapu <pradeepc@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
