[PATCH 4.9 225/264] ASoC: cs42l52: Fix TLV scales for mixer controls

From: Greg Kroah-Hartman
Date: Thu Jun 23 2022 - 13:10:30 EST


From: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxx>

[ Upstream commit 8bf5aabf524eec61013e506f764a0b2652dc5665 ]

The datasheet specifies the range of the mixer volumes as between
-51.5dB and 12dB with a 0.5dB step. Update the TLVs for this.
