Subject: [PATCH 2/5] ASoC: stm32: sai: fix exposed capabilities in spdif mode
Date: Thu, 28 Feb 2019 14:19:22 +0100 [thread overview]
Message-ID: <1551359965-25228-3-git-send-email-olivier.moysan@st.com> (raw)
In-Reply-To: <1551359965-25228-1-git-send-email-olivier.moysan@st.com>
Change capabilities exposed in SAI S/PDIF mode, to match
actually supported formats.
In S/PDIF mode only 32 bits stereo is supported.
