Hi Abel,
Thanks for the patch. I am not the maintainer nor an official reviewer but I submitted some patches in the mfd system and below is a review based on some comments I received when I posted a driver. So hope will be helpful for you.

For new drivers a better explanation of what the chip is and what supports is appreciable ;)

I think that the general consensus is to remove the GPL notice once you have added the SPDX License Identifier. So this notice is not required.

Is the pf1550-regulator submitted to upstream? I did not find it, I think that is better introduce this compatible when the driver and the documentation is in place.

Same here.

Ok, I see that you submitted the driver in this series, the documentation is also missing.

Alignment should match open parenthesis again.
IMHO is a good idea running checkpatch with --strict, you will catch these things.

Use the device managed version devm_regmap_add_irq_chip

You can use the managed version devm_mfd_add_devices.
Also, -1 has his own define which is PLATFORM_DEVID_NONE, use that instead.

All this error handling can be simplified using the device managed versions.

The full function can be remove after move to device managed version of these functions.

Adding sentinel is a good practice

Replace this with SIMPLE_DEV_PM_OPS helper macro.

"fsl,pf1550" appears un-documented. You need to add the documentation binding for this.

Add sentinel and remove the comma.

Guess you are missing the module device table here.

An i2c driver does not need the owner, the core does it for you, so you can remove this field.

If I am not wrong subsys_initcall is guaranteed to be executed before the procedure declared as module_init, but this only makes sense when the driver is built-in. Your driver can be built as a module and I think that should be possible as module, so I am wondering if you really need to use the subsys_initcall here or if you can simply use the helper macro for registering a modular I2C driver and remove the __init and __exit functions.
