Subject: [PATCH v5 08/17] ASoC: tegra20: i2s: Add system level suspend-resume callbacks
Date: Sun, 14 Mar 2021 18:44:50 +0300	[thread overview]
Message-ID: <20210314154459.15375-9-digetx@gmail.com> (raw)
In-Reply-To: <20210314154459.15375-1-digetx@gmail.com>

Add system level suspend-resume callbacks in order to ensure that I2S
is gated before system is suspended. This puts Tegra20 I2S driver on
par with the Tegra30 I2S driver.
