Shengjiu Wang	337d348b83	ASoC: ak4458: Add DSD support for ak4458 and ak4497 ... Ak4458 can't support DSD512 format, but ak4497 can, so add a new enum variable (enum ak4458_type) in ak4458_drvdata to distinguish these two platforms. Ak4497 has two kinds of DSD input pin, it can be selected by the dsd-path property from DT. In hw_params(), bit clock is calculated according to different DSD format (DSD64, DSD128, DSD256, DSD512), then registers are configured.

Cosmin-Gabriel Samoila	08660086ef	ASoC: ak4458: Add support for AK4458 DAC driver ... The AK4458 is a 32-bit 8ch Premium DAC that corresponds to a 768kHz PCM input and an 11.2MHz DSD input at maximum. It supports I2S, DSD and TDM modes with 24 or 32 bit MSB or 16, 24, 32 LSB formats.
