From 40c3a445422579db8ad96c234dbe6c0ab3f6b936 Mon Sep 17 00:00:00 2001 From: Marius Zachmann Date: Fri, 26 Jun 2020 07:59:36 +0200 Subject: 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.
