Subject: [PATCH] ASoC: AMD: Set constraints for DMIC and MAX98357a codec
Date: Tue, 21 Aug 2018 12:25:05 +0530 [thread overview]
Message-ID: <1534834520-18397-1-git-send-email-akshu.agrawal@amd.com> (raw)
We support dual channel, 48Khz. This constraint was set only for
da7219. It is being extended to DMIC and MAX98357a.
