[PATCH 0/5] Convert to use regmap framework's endianness method.

[PATCH 0/5] Convert to use regmap framework's endianness method.

[Xiubo Li]

Changes in V2:
- Modified the regmap config to const type.
- Added ASRC patch.
- Followed Rutland's advice.


Xiubo Li (5):
  ASoC: fsl-asrc: Convert to use regmap framework's endianness method.
  ASoC: fsl-esai: Convert to use regmap framework's endianness method.
  ASoC: fsl-spdif: Convert to use regmap framework's endianness method.
  ASoC: fsl-sai: Convert to use regmap framework's endianness method.
  ASoC: fsl-sai: rename big_endian_data to is_msb_first.
