In the Pine64 PinePhone, the stk3310 chip is powered by a regulator that is disabled at system boot and can be shut off during suspend. To ensure that the chip properly initializes, both after boot and suspend, we need to manage this regulator.
Additionally if the chip is shut off in suspend, we need to make sure that it gets reinitialized with the same parameters after resume.
Major changes in v2: - Add handling of the IR LED. I was hesitant to include this as it is the same as pull-up regulator for the i2c bus on the hardware I have, so I can't test it well. I think leaving it out is more likely to cause issues than including it. - Convert stk3310 to use dev_err_probe for errors. - Always enable / disable regulators and rely on dummy devices if they're not specified. - more listed in individual patches
