From 8987986b07f5dded3f81b159f5bb146f2d1a21ed Mon Sep 17 00:00:00 2001 From: Lucas Tanure Date: Thu, 9 Mar 2023 14:00:51 +0000 Subject: ASoC: cs35l41: Steam Deck Shared boost properties quirk Add support for Steam Deck bios old properties. If a Steam deck didn't upgrade the BIOS, the driver should be able to handle the previous properties for shared boost types.
