From b8c451e375746d1ed9d2276e261be3fbf6dd67d4 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Mon, 25 Mar 2024 10:10:31 -0500 Subject: mb/google/beltino: Set initial fan PWM to 30% Recent changes to the ITE 8772F SIO code caused the initial fan PWM to change from 0 to 50%; set it to 30% to reduce fan noise while still providing some temp control before the OS/ACPI takes over. TEST=build/boot google/beltino to payload, verify fan noise is negligible.
