Re: [alsa-devel] [PATCH 3/6] ASoC: da7219: Update REFERENCES reg default, in-line with HW

In current AB silicon, BIAS_EN field is enabled by default in the REFERENCES register, so the regmap default value should reflect this.

This is the sort of thing where a register patch would normally be used - if you put in a register patch for the older silicon then the driver can correct for the register default automatically.
