Subject: [PATCH 0/2] ASoC: stm32: dfsdm: change rate limits
Date: Wed, 7 Oct 2020 17:34:57 +0200 [thread overview]
Message-ID: <20201007153459.22155-1-olivier.moysan@st.com> (raw)
Widening of the supported rate range in the STM32 DFSDM driver.
The rates were previously limited to 8kHz, 16kHz and 32kHz.
Allow rate capture in the whole range 8kHz-48kHz as there is no hardware
limitation to support it.
Actual sample resolution is dependent on audio rate and DFSDM configuration.
Add a trace to allow simple check of sample resolution.
