Subject: [PATCH v2 2/4] HID: usbhid: Share USB device devicetree node with child HID device
Date: Fri, 3 Feb 2023 22:43:11 -0600 [thread overview]
Message-ID: <20230204044313.364-3-kaehndan@gmail.com> (raw)
In-Reply-To: <20230204044313.364-1-kaehndan@gmail.com>
USB HID core now shares its devicetree of_node with its child HID device.
Since there can only be one HID device on a USB interface, it is redundant
to specify a hid node under the USB device (and further, binding this way
isn't currently possible, as hid_driver does not support of_match_table).
