+Date:		December 2023
+Contact:	linux-input@vger.kernel.org
+Description:	Set the mode the ROG Ally xpad operates in:
+		- 1 = Game mode
+		- 2 = WASD mode
+		- 3 = Mouse mode
+		This setting applies instantly and applies settings that were previously changed
+		under that mode which are:
+		- deadzones
+		- anti-deadzones
+		- button mapping
+		- button turbo settings
+		- response curves

+Description:	Apply the settings that have been stored in attributes so far. Because there are
+		many individual settings across a dozen packets this separation is required to
+		prevent spamming the MCU when userspace applications apply many changes at once.
