From 0d52aafb8bcee01b11ec8f3b46050540585431eb Mon Sep 17 00:00:00 2001 From: Cristian Ciocaltea Date: Wed, 25 Jun 2025 00:56:45 +0300 Subject: [PATCH 01/14] HID: playstation: Make use of bitfield macros Improve code readability and make it more robust by replacing open coded bit operations with the equivalent bitfield macros. While at it, also fix the vertical alignment for some of the bitfield constants.

Detect when the plugged state of the 3.5mm audio jack changes and toggle audio output between headphones and internal speaker, as required. The latter is achieved by essentially routing the right channel of the audio source to the mono speaker. Additionally, adjust the speaker volume since its default level is too low and, therefore, cannot generate any audible sound. It's worth noting the audio functionality is currently not supported for Bluetooth, hence it's limited to USB connectivity.
