Re: [alsa-devel] [PATCH 5/7] ASoC: TWL4030: Helper to check chip default registers

Is this purely for information/debug purposes ?

Yes, the driver support twl4030, twl5030, twl5031, tps*something* chips. If someone, who have access to those chips, and in doubt, can check it.

Why do we need to check default vales at init(). Is there another driver changing the audio codec registers ?

This driver is going to change it. It is also possible that the bootloader changed them (startup tone?). So it is not really bulletproof, but at least it helped me to find out the the ARXR2_APGA_CTL register does not have the reset value, which it supposed to have.

Well, I can remove it, but I thought that it is a nice touch ;)

Thanks
