From bf29bafe3eaa8b8582407967755dbcd940a30287 Mon Sep 17 00:00:00 2001 From: Aaron Webster Date: Mon, 6 Apr 2026 21:40:08 -0700 Subject: [PATCH] HID: playstation: Add DualSense Edge extra button support The DualSense Edge controller (product ID 0x0df2) has four additional buttons compared to the standard DualSense: two front function buttons (Fn1 and Fn2) and two rear paddles (left and right). These are reported in bits 4-7 of buttons[2] in the input report. Map them to BTN_TRIGGER_HAPPY1 through BTN_TRIGGER_HAPPY4 so that userspace applications can use these extra inputs. An is_edge flag gates the extra button handling based on the product ID.
