Subject: [PATCH 0/2] ASoC: cs35l56: Support for restoring calibration on ChromeOS
Date: Tue, 11 Nov 2025 13:08:48 +0000 [thread overview]
Message-ID: <20251111130850.513969-1-rf@opensource.cirrus.com> (raw)
These two patches add ALSA controls to support restoring factory calibration
during OS boot on ChromeOS.
ChromeOS applies calibration during boot using a process that has restricted
access permissions. This process needs ALSA controls for all settings that
it must restore.
