From 244389bd42870640c4b5ef672a360da329b579ed Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Wed, 3 Jul 2024 10:55:17 +0100 Subject: ASoC: cs35l56: Limit Speaker Volume to +12dB maximum Change CS35L56_MAIN_RENDER_USER_VOLUME_MAX to 48, to limit the maximum value of the Speaker Volume control to +12dB. The minimum value is unchanged so that the default 0dB has the same integer control value. The original maximum of 400 (+100dB) was the largest value that can be mathematically handled by the DSP. The actual maximum amplification is +12dB.
