Subject: [PATCHv4 7/9] ASoC: fsl-asoc-card: add DT clock "cpu_sysclk" with generic codec
Date: Wed, 15 May 2024 15:54:09 +0200	[thread overview]
Message-ID: <20240515135411.343333-8-elinor.montmasson@savoirfairelinux.com> (raw)
In-Reply-To: <20240515135411.343333-1-elinor.montmasson@savoirfairelinux.com>

Add an optional DT clock "cpu_sysclk" to get the CPU DAI system-clock
frequency when using the generic codec.
It is set for both Tx and Rx.
The way the frequency value is used is up to the CPU DAI driver
implementation.
