This adds the possibility for reading pwm values. These can not be read if the device is controlled via fan_target or a fan curve and will return an error in this case. Since an error is expected, this adds some rudimentary error handling. Changes: - add CTL_GET_FAN_PWM and use it via get_data - pwm returns -ENODATA if the device returns error 0x12 - fan_target now returns -ENODATA when the driver is started or a pwm value is set. - add ccp_get_errno to determine errno from device error. - get_data now has a parameter to determine whether to read one or two bytes of data. - update documentation - fix missing surname in MAINTAINERS Signed-off-by: Marius Zachmann <mail@mariuszachmann.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

Description
|
|
-----------
|
|
|
|
This driver implements the sysfs interface for the Corsair Commander Pro.
|
|
The Corsair Commander Pro is a USB device with 6 fan connectors,
|
|
4 temperature sensor connectors and 2 Corsair LED connectors.
|
|
It can read the voltage levels on the SATA power connector.
|
|
|
|
Usage Notes
|
|
-----------
|
|
|
|
Since it is a USB device, hotswapping is possible. The device is autodetected.

|
|
in0_input Voltage on SATA 12v
|
|
in1_input Voltage on SATA 5v
|
|
in2_input Voltage on SATA 3.3v
|
|
temp[1-4]_input Temperature on connected temperature sensors
|
|
fan[1-6]_input Connected fan rpm.
|
|
fan[1-6]_label Shows fan type as detected by the device.
|
|
fan[1-6]_target Sets fan speed target rpm.
|
|
When reading, it reports the last value if it was set by the driver.
|
|
Otherwise returns an error.
|
|
pwm[1-6] Sets the fan speed. Values from 0-255. Can only be read if pwm
|
|
was set directly.
