There are two separate drivers in this series that are modeled to provide a sysfs that is as close to each other as possible. Because of that, they do end up having identical attributes for many of the implemented features. In most cases they are prefixed in the sysfs by a different component name, but that isn't the case for os_mode or touchpad/enabled. I could combine documentation for both drivers and de-duplicate, but I'm not sure what that would be called, sysfs-driver-hid-lenovo-go? Add them all to hid-lenovo docs? If I do that there are some additional de-duplication that could reduce the total number of lines. I.E What: /sys/class/leds/[go|go_s]:rgb:joystick_rings/effect Would that syntax be alright? Some of them get a little excessive, for example the auto sleep time is defined three times and would be combined to something like this: What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/[left_handle|right_handle|gamepad]/auto_sleep_time Otherwise, is there some way to flag the same attribute defined in two separate documents provided by two drivers as not being duplicates?
