Date: Fri, 18 Dec 2020 22:23:30 -0800 Message-Id: <20201219062336.72568-8-roderick@gaikai.com> X-Mailer: git-send-email 2.26.2 In-Reply-To: <20201219062336.72568-1-roderick@gaikai.com> References: <20201219062336.72568-1-roderick@gaikai.com> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-input@vger.kernel.org From: Roderick Colenbrander This patch adds support for the DualSense when operating in Bluetooth mode. The device has the same behavior as the DualShock 4 in that by default it sends a limited input report (0x1), but after requesting calibration data, it switches to an extended input report (report 49), which adds data for touchpad, motion sensors, battery and more.
