Subject: [PATCH 0/3] Export the target RPM fan control by ChromeOS EC under
 hwmon

ChromeOS embedded controller (EC) supports closed-loop fan control. We
anticipate to have the fan related control from the kernel side, so this
series register the HWMON_F_TARGET attribute, and implement the read and
write function for setting/reading the target fan RPM from the EC side.
