mb/google/brya/var/banshee: Add mic mute switch setting
Using the GPP_F22 as mic mute switch based on the latest schematic. BUG=b:223737606, b:216110896 BRANCH=firmware-brya-14505.B TEST=emerge-brya coreboot chromeos-bootimage The mic_mute event is changed when the mic_mute GPIO pin is switched. Event: time 1647939954.639995, type 5 (EV_SW), code 14 (SW_MUTE_DEVICE), value 0 Event: time 1647939954.639995, -------------- SYN_REPORT ------------ Event: time 1647939954.648152, type 5 (EV_SW), code 14 (SW_MUTE_DEVICE), value 1 Event: time 1647939954.648152, -------------- SYN_REPORT ------------ Signed-off-by: Frank Wu <frank_wu@compal.corp-partner.google.com> Change-Id: I6f7176afbd64f7c080f02369f195043a2df88e5d Reviewed-on: https://review.coreboot.org/c/coreboot/+/62804 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com>
