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.

+Supported devices:
+
+ * Corsair Commander Pro
+ * Corsair Commander Pro (1000D)

+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.
