From 32ec29a51e9cfd6e07c793e867a59ab455081cd4 Mon Sep 17 00:00:00 2001 From: Norman Bintang Date: Tue, 28 Oct 2025 18:34:14 +0800 Subject: [PATCH] mb/google/fatcat/var/kinmen: Disable RT721 clock stop support This change applies the same fix as coreboot change CB:89605 to the kinmen variant. Without this change, headset jack detection won't work. The original change 752d49a4ffe98b731eb5a7c1beccff49f0418faa was: "mb/google/fatcat/var/moonstone: Disable RT721 clock stop support" RT721 headset jack detection fails because the wakeup event is not triggered during runtime suspend in D3 state. Disable the clock stop to allow the bus driver to handle the wakeup process properly. The MIPI Disco property is "mipi-sdw-simplified-clockstopprepare-sm-supported". BUG=b:435094908 TEST=After plugging a headset, audio output is switched to it.
