There are three methods:
- pass different registers to snd_soc_read and snd_soc_write. But
snd_kcontrol and snd_soc_dapm_widget can't work because I pass only one register. 2. deal with this bit in hw_read, but this will be deprecated by others whose chip doesn't have this bit. 3. I'd like to use SND_SOC_CUS type, but it has been removed since linux 3.0. I suggest we can reserve this type, considering SPI is a simple "de facto" standard.
No, like I say we just need to teach regmap about this stuff. It's not that odd, it's just your hardware designers seem to want to consume extra bandwidth on the control bus for some reason AFAICT as it looks like all the registers are 0x8xx.
