2022-01-27ASoC: imx-card: improve the sound quality for low rateShengjiu Wang1-4/+4
[ Upstream commit 3969341813eb56d2dfc39bb64229359a6ae3c195 ] According to RM, on auto mode: For codec AK4458 and AK4497, the lowest ratio of MLCK/FS is 256 if sample rate is 8kHz-48kHz, For codec AK5558, the lowest ratio of MLCK/FS is 512 if sample rate is 8kHz-48kHz. With these setting the sound quality for 8kHz-48kHz can be improved.

2022-01-27ASoC: imx-card: Fix mclk calculation issue for akcodecShengjiu Wang1-3/+4
[ Upstream commit f331ae5fa59fbfb748317b290648fc3f1a50d932 ] Transfer the refined slots and slot_width to akcodec_get_mclk_rate() for mclk calculation, otherwise the mclk frequency does not match with the slots and slot_width for S16_LE format, because the default slot_width is 32.

2022-01-27ASoC: imx-card: Need special setting for ak4497 on i.MX8MQShengjiu Wang1-1/+16
[ Upstream commit 3349b3d0c63b8b6fcca58156d72407f0b2e101ac ] The SAI on i.MX8MQ don't support one2one ratio for mclk:bclk, so the mclk frequency exceeds the supported range of codec for the case that sample rate is larger than 705kHZ and format is S32_LE. Update the supported width for such case.

2021-05-20ASoC: imx-card: Add imx-card machine driverShengjiu Wang1-0/+844
Add machine driver for i.MX boards, which supports AK4458/AK5558/AK4497/AK5552 DAC/ADC attached to SAI interface currently, but these DAC/ADCs are not only supported codecs. This machine driver is designed to be a more common machine driver for i.MX platform, it can support widely cpu dai interface and codec dai interface.
