Subject: [alsa-devel] [PATCH v4 2/7] ASoC: tegra: Allow 24bit and 32bit samples
Date: Mon, 7 Oct 2019 16:31:31 +0100 [thread overview]
Message-ID: <20191007153136.4920-3-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <20191007153136.4920-1-ben.dooks@codethink.co.uk>
From: Edward Cragg <edward.cragg@codethink.co.uk>
The tegra3 audio can support 24 and 32 bit sample sizes so add the
option to the tegra30_i2s_hw_params to configure the S24_LE or S32_LE
formats when requested.
Signed-off-by: Edward Cragg <edward.cragg@codethink.co.uk>
