Subject: [PATCH 11/13] HID: playstation: add DualSense player LEDs support.
Date: Fri, 18 Dec 2020 22:23:34 -0800	[thread overview]
Message-ID: <20201219062336.72568-12-roderick@gaikai.com> (raw)
In-Reply-To: <20201219062336.72568-1-roderick@gaikai.com>

From: Roderick Colenbrander <roderick.colenbrander@sony.com>

The DualSense features 5 player LEDs below its touchpad, which are
meant as player id indications. This patch exposes the player LEDs
as individual LEDs.
