Matteo Martelli b9bb963436 ASoC: sunxi: sun4i-i2s: fix LRCLK polarity in i2s mode ... [ Upstream commit 3e83957e8d ] This fixes the LRCLK polarity for sun8i-h3 and sun50i-h6 in i2s mode which was wrongly inverted. The LRCLK was being set in reversed logic compared to the DAI format: inverted LRCLK for SND_SOC_DAIFMT_IB_NF and SND_SOC_DAIFMT_NB_NF; normal LRCLK for SND_SOC_DAIFMT_IB_IF and SND_SOC_DAIFMT_NB_IF. Such reversed logic applies properly for DSP_A, DSP_B, LEFT_J and RIGHT_J modes but not for I2S mode, for which the LRCLK signal results reversed to what expected on the bus. The issue is due to a misinterpretation of the LRCLK polarity bit of the H3 and H6 i2s controllers. Such bit in this case does not mean "0 => normal" or "1 => inverted" according to the expected bus operation, but it means "0 => frame starts on low edge" and "1 => frame starts on high edge" (from the User Manuals). This commit fixes the LRCLK polarity by setting the LRCLK polarity bit according to the selected bus mode and renames the LRCLK polarity bit definition to avoid further confusion.
