Dear Mark, Liam
Better yet would be to just select the appropriate set of register defaults based on the device being used at system startup - that way the driver gets the benefits of the default table (eg, reducing the number of writes done at system startup and resume) and doesn't need to delay boot to read the full register map.
(snip)
To be honest, this is only really useful when the codec has some volatile registers. Forcing I2C reads for all IO will just slow down the driver.
I understand about this. sorry. I just didn't know that.
In my check, it seems don't have volatile registers. so please drop it.
