0cd1ef3f7b ASoC: imx-card: improve the sound quality for low rate 
[ Upstream commit 3969341813 ]

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.

edc07df0df ASoC: imx-card: Fix mclk calculation issue for akcodec 
[ Upstream commit f331ae5fa5 ]

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.

6bedc3b3d1 ASoC: imx-card: Need special setting for ak4497 on i.MX8MQ 
[ Upstream commit 3349b3d0c6 ]

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.

d5bd87e3a3 ASoC: imx-card: Make some symbols static 
The sparse tool complains as follows:

sound/soc/fsl/imx-card.c:121:27: warning:
 symbol 'ak4458_fs_mul' was not declared. Should it be static?
sound/soc/fsl/imx-card.c:138:31: warning:
 symbol 'ak4458_tdm_fs_mul' was not declared. Should it be static?
sound/soc/fsl/imx-card.c:149:27: warning:

sound/soc/fsl/imx-card.c:166:27: warning:

sound/soc/fsl/imx-card.c:180:31: warning:
 symbol 'ak5558_tdm_fs_mul' was not declared. Should it be static?

Those symbols are not used outside of imx-card.c, so marks
them static.

aa736700f4 ASoC: imx-card: Add imx-card machine driver 
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.
