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.

Applied all three, thanks.

Liam was just mentioning on IM that it might be worth looking at pulling the cache and I/O code out of ASoC for use by other I2C/SPI based subsystems. I'll take a look at that.
