Subject: [PATCH] ASoC: rockchip: i2s-tdm: fix shift config for
SND_SOC_DAIFMT_DSP_[AB]
[ Upstream commit 6b24e67b4056ba83b1e95e005b7e50fdb1cc6cf4 ]
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")
