hwmon: add Corsair Commander Pro driver 



This is v7 of a driver for the Corsair Commander Pro.
It provides sysfs attributes for:
- Reading fan speed
- Reading temp sensors
- Reading voltage values
- Writing pwm and reading last written pwm
- Reading fan and temp connection status

It is an usb driver, so it needs to be ignored by usbhid.
The Corsair Commander Pro is a fan controller and provides
no means for user interaction.
The two device numbers are there, because there is a slightly
different version of the same device. (Only difference
seem to be in some presets.)

Squashed:
 hwmon: (corsair-cpro) add fan_target

 This adds fan_target entries to the corsair-cpro driver.
 Reading the attribute from the device does not seem possible, so
 it returns the last set value (same as pwm).

 send_usb_cmd now has one more argument, which is needed for the
 fan_target command.

 hwmon: corsair-cpro: Change to HID driver

 This changes corsair-cpro to a hid driver using hid reports.

Kernel driver corsair-cpro

==========================



Supported devices:



  * Corsair Commander Pro

  * Corsair Commander Pro (1000D)



Author: Marius Zachmann



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.



Sysfs entries

-------------



======================= =====================================================================

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 0.

pwm[1-6]		Sets the fan speed. Values from 0-255.

			When reading, it reports the last value if it was set by the driver.

			Otherwise returns 0.
