Subject: [PATCHv4 8/9] ASoC: fsl-asoc-card: add DT property "cpu-system-clock-direction-out"
Date: Wed, 15 May 2024 15:54:10 +0200 [thread overview]
Message-ID: <20240515135411.343333-9-elinor.montmasson@savoirfairelinux.com> (raw)
In-Reply-To: <20240515135411.343333-1-elinor.montmasson@savoirfairelinux.com>
Add new optional DT property "cpu-system-clock-direction-out" to set
sysclk direction as "out" for the CPU DAI when using the generic codec.
It is set for both Tx and Rx.
If not set, the direction is "in".
The way the direction value is used is up to the CPU DAI driver
implementation.
