Subject: [PATCH v3 3/4] ASoC: cs35l45: Connect DSP to the monitoring signals
Date:   Thu, 31 Aug 2023 11:20:41 -0500
Message-ID: <20230831162042.471801-3-vkarpovi@opensource.cirrus.com>

Link VMON, IMON, TEMPMON, VDD_BSTMON and VDD_BATTMON
to DSP1. The CSPL firmware uses them for the speaker calibration
and monitoring.
