As an example of this is the audio block's ANAMICL register. In normal operation the content can be cached but during initialization one bit from the register need to be monitored. With the twl_set_regcache_bypass() the client driver can switch regcache bypass on and off when it is needed so we can utilize the regcache for more registers.
