hwmon: Add driver for ASUS ROG RYUJIN II 360 AIO cooler
This driver exposes hardware sensors of the ASUS ROG RYUJIN II 360
all-in-one CPU liquid cooler, which communicates through a proprietary
USB HID protocol. Report offsets were initially discovered in [1] by
Florian Freudiger.
Available sensors are pump, internal and external
(controller) fan speed in RPM, their duties in PWM, as well as
coolant temperature.
Attaching external fans to the controller is optional and allows them
to be controlled from the device. If not connected, the fan-related
sensors will report zeroes. The controller is a separate hardware unit
that comes bundled with the AIO and connects to it to allow fan control.
The addressable LCD screen is not supported in this
driver and should be controlled through userspace tools.
