Subject: [PATCH v6 5/6] ASoC: amd: Handle ACP3x I2S-SP Interrupts.
Date: Fri, 15 Nov 2019 17:40:22 +0530 [thread overview]
Message-ID: <1573819823-23731-6-git-send-email-Vishnuvardhanrao.Ravulapati@amd.com> (raw)
In-Reply-To: <1573819823-23731-1-git-send-email-Vishnuvardhanrao.Ravulapati@amd.com>
Enabled support for I2S-SP interrupt handling.
Previous to this implementation, driver supports only interrupts
on BT instance.
