Re: [alsa-devel] [PATCH v2 1/3] ASoC: soc-cache: Add support for default readable()/volatile() functions

For common scenarios, device drivers can provide a table of all the registers that are at least either readable/writable/volatile. The idea is that if a register lookup fails, all of its read/write/vol members will be zero and will be treated as default. This also reduces the size of the register access array.

I think we may be getting to the point where we should probably look into making this register cache functionality available to other non ASoC I2C and SPI based drivers.

Thanks
