4627ecec79 mfd: rt5033: Replace irqchip mask_invert with unmask_base
Remove use of the deprecated mask_invert flag. Inverted mask
registers (where a '1' bit enables an IRQ) can be described more
directly as an unmask register.

e46b578cab mfd: rt5033: Convert to i2c's .probe_new()
The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

a232bcd201 mfd: rt5033: Drop of_match_ptr from of_device_id table
The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it is not relevant here).  This fixes
compile warning (!CONFIG_OF on x86_64):

  drivers/mfd/rt5033.c:116:34: warning: ‘rt5033_dt_match’ defined but not used [-Wunused-const-variable=]

6b719eba9f mfd: rt5033: Use devm_mfd_add_devices() for mfd_device registration
Use devm_mfd_add_devices() for MFD devices registration and get
rid of .remove callback to remove MFD child-devices. This is done
by managed device framework.

4a32229668 mfd: rt5033: Remove unnecessary MODULE_ALIAS()
The driver has a I2C device id table that is used to create the module
aliases which already contains a "rt5033". So the alias is not needed.

4895e493f9 mfd: Export OF module alias information in missing drivers
The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So technically there's no need for a driver to export
the OF table since currently it's not used.

In fact, the I2C device ID table is mandatory for I2C drivers since
a i2c_device_id is passed to the driver's probe function even if the
I2C core used the OF table to match the driver.

And since the I2C core uses different tables, OF-only drivers needs to
have duplicated data that has to be kept in sync and also the dev node
compatible manufacturer prefix is stripped when reporting the MODALIAS.

To avoid the above, the I2C core behavior may be changed in the future
to not require an I2C device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table to prevent
breaking module autoloading if that happens.
