Subject: [PATCH v3 2/5] ASoC: fsl_sai: Update Tx/Rx channel enable mask
Date: Tue, 6 Aug 2019 18:12:11 +0300 [thread overview]
Message-ID: <20190806151214.6783-3-daniel.baluta@nxp.com> (raw)
In-Reply-To: <20190806151214.6783-1-daniel.baluta@nxp.com>
Tx channel enable (TCE) / Rx channel enable (RCE) bits
enable corresponding data channel for Tx/Rx operation.
Because SAI supports up the 8 channels TCE/RCE occupy
up the 8 bits inside TCR3/RCR3 registers we need to extend
the mask to reflect this.
