Why should this regulator be always on? The wm8962.c driver can handle
the regualtor enable/disable.

Is it intended to use capitalized and no-capitalized regulator-name's?

Can we squash regulator-audio-pwr-en and regulator-audio-v1v8?

Either I would bundle all clock settings here or within the sai nodes.

Out of curiosity, why did you marked all regulators as
regulator-always-on? I thought the librem5 is a smartphone.

You need to mux the irq gpio.

irq-gpios is not supported by the driver. We only have a

Please check that "reg" is always the 2nd property after the

The compatible should be "ti,bq25895" if it is a bq25895. So we can drop

I would only mention the units within a comment because comments like
