[PATCH] ASoC: rockchip: i2s-tdm: fix shift config for SND_SOC_DAIFMT_DSP_[AB]

From: John Keeping
Date: Tue Feb 04 2025 - 11:13:46 EST


Commit 2f45a4e289779 ("ASoC: rockchip: i2s_tdm: Fixup config for
SND_SOC_DAIFMT_DSP_A/B") applied a partial change to fix the
configuration for DSP A and DSP B formats.

The shift control also needs updating to set the correct offset for
frame data compared to LRCK. Set the correct values.

Fixes: 081068fd64140 ("ASoC: rockchip: add support for i2s-tdm controller")
