From: Roderick Colenbrander <roderick.colenbrander@xxxxxxxx> Hi, Recently Sony released a HID driver for the new PlayStation 5 controller 'DualSense'. Pavel Machek noticed the driver got staged for "-next" and asked me to share the LED patches to linux-leds as well. The LED patches I'm sharing are patch 6, 9, 11, 12 from the v6 hid-playstation series as originally posted to linux-input. The driver in its full form can be found on "hid.git/log/?h=for-5.12/playstation". A little bit of background on the DualSense controller. It is a generic HID gamepad (e.g. buttons and sticks) with a number of additional features, such as Motion Sensors, audio, LEDs and others. All features are implemented using HID input and output reports. In regards to LEDs it has 3 types of LEDs. First, it has a RGB lightbar which is used in PS4/PS5 games for various effects e.g. health indicator, police siren, player color and other use cases. This patch series exposes it using the multicolor class, which is great for our use case as the lightbar state is sent using a single HID output report. Previously for our DualShock 4 controller, the driver exposed individual LEDs, which wasn't great due to race conditions as games change LED state frequently. The second LED type, is a row of 5 player indicator LEDs. Such LEDs are common on gamepads to set a player number e.g. 1, 2, 4 etcetera. Each LED is exposed as a single LED. A default player id is set based on the number of connected controllers, which is common behavior within the input system. Finally, the DualSense has a audio mute LED and a mute button. The mute button is expected to mute the internal microphone of the DualSense. The mute behavior is handled driver side and the driver then also programs the LED. From user space perspective the LED is read-only. Let me know if there are any questions or comments. Thanks, Roderick Colenbrander Sony Interactive Entertainment, LLC Roderick Colenbrander (13): HID: playstation: add DualSense lightbar support HID: playstation: add microphone mute support for DualSense. HID: playstation: add DualSense player LEDs support. HID: playstation: DualSense set LEDs to default player id.
