[alsa-devel] RFC: reworking ASOC for large registers

[Jon Smirl]

These signatures need to change a lot:

/* codec register bit access */
int snd_soc_update_bits(struct snd_soc_codec *codec, unsigned short reg,
				unsigned short mask, unsigned short value);
int snd_soc_test_bits(struct snd_soc_codec *codec, unsigned short reg,
				unsigned short mask, unsigned short value);


Something like:
int snd_soc_update_bits(struct snd_soc_codec *codec, uint reg,
				uint mask, uint shift, u64 value);

shift is needed to shift the mask around for huge registers like 256
bits. For existing hardware it will always be zero. value has to go to
u64.
