mfd: max77686: Drop of_match_ptr from of_device_id table

2020-11-27T08:02:19+00:00

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/max77686.c:148:34: warning: ‘max77686_pmic_dt_match’ defined but not used [-Wunused-const-variable=]

mfd: max77686: Remove I2C device ID table

2017-02-13T09:29:43+00:00

The driver is only used in DT platforms so there's no need to
have an i2c_device_id table.

mfd: max77686: Use the struct i2c_driver .probe_new instead of .probe

2017-02-13T09:29:43+00:00

If a driver is only used in DT platforms, there's no need to get the
i2c_device_id as an argument of the probe function. Since this data
can be get from the matching of_device_id.

There's a temporary .probe_new field in struct i2c_driver that can be
used as probe callback for the case when i2c_device_id won't be used.

mfd: max77686: Use of_device_get_match_data() helper

2017-02-13T09:29:43+00:00

Use the generic helper to get the matched of_device_id .data, instead of
open coding it.

The driver was checking if matching the OF node with the driver's OF table
was failing, but this doesn't make too much sense since this can't happen
in practice. The fact the probe function was called, means OF registered a
device with a valid compatible string so a of_device_get_match_data() call
will always succeed. So just remove this unneeded check.

mfd: max77686: Don't attempt to get i2c_device_id .data

2017-02-13T09:29:43+00:00

The driver is only used in platforms that have DT support so always the
I2C device .data will be get from the matched OF node and never will be
from the I2C device ID table.

mfd: max77686: Use devm_mfd_add_devices and devm_regmap_add_irq_chip

2016-05-09T12:27:20+00:00

Use devm_mfd_add_devices() for adding MFD child devices and
devm_regmap_add_irq_chip() for IRQ chip registration.

This reduces the error code path and .remove callback for removing
MFD child devices and deleting IRQ chip data.

mfd: max77686: Use module_i2c_driver() instead of subsys initcall

2016-04-19T06:59:28+00:00

The driver's init and exit function don't do anything besides adding and
deleting the I2C driver so the module_i2c_driver() macro could be used.

Currently is not being used because the driver is initialized at subsys
initcall level, claiming that this is done to allow consumers devices to
use the resources provided by this driver. But dependencies are in DT so
manual ordering of init calls is not necessary any more.
