One thing I'm not clear on is if there's some way to ensure that we don't have different instances of the device resetting each other without them noticing? Shouldn't be an issue in practice for the use here.
The way to ensure that we don't have different instances of the device resetting each other is to rely on the way the "shared" reset is handled by reset API: ==========
- ak4458->reset = devm_reset_control_get_optional_shared(ak4458->dev, NULL);
- if (IS_ERR(ak4458->reset))
return PTR_ERR(ak4458->reset);==========
Flip side of that then, how do we know when a reset has actually happened?
