Subject: [alsa-devel] [PATCH v4 5/7] ASoC: tegra: set i2s_offset to 0 for tdm
Date: Mon, 7 Oct 2019 16:31:34 +0100 [thread overview]
Message-ID: <20191007153136.4920-6-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <20191007153136.4920-1-ben.dooks@codethink.co.uk>
Set the offset to 0 for TDM mode, as per the current setup. Note we also
move the data offset programming to the i2s hw_parameters call as per
the suggestion from Jon Hunter.
Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk>
---
v2:
- fix the review comments and move the i2s offset setting
v3:
- fix data-offset for dsp-a and dsp-b
