mfd: max8997: Simplify getting of_device_id match data

2021-06-02T09:51:17+00:00

Use of_device_get_match_data() to make the code slightly smaller.  There
is also no need to wrap it in a check for CONFIG_OF, because dev.of_node
will be set only with OF support.

Revert "mfd: max8997: Add of_compatible to Extcon and Charger mfd_cell"

2021-04-14T15:06:53+00:00

This reverts commit 9c03008da125c1007919a9186628af3cc105f526.

commit 41a8a027f4d3 ("regulator: dt-bindings: Document charger-supply
for max8997") introduced a binding which uses a property of the max8997
pmic node to configure charger supply, making subnodes for MFD cells
obsolete.

mfd: max8997: Add of_compatible to Extcon and Charger mfd_cell

2021-02-08T13:54:09+00:00

Add of_compatible ("maxim,max8997-muic") to the mfd_cell to have a
of_node set in the extcon driver.

Add of_compatible ("maxim,max8997-battery") to the mfd_cell to configure
the charger driver.

mfd: max8997: Convert to i2c_new_dummy_device

2019-08-12T07:53:58+00:00

Move from i2c_new_dummy() to i2c_new_dummy_device(), so we now get an
ERRPTR which we use in error handling.

mfd: max8997: Disable interrupt handling for suspend/resume cycle

2018-10-23T07:58:34+00:00

Disable IRQs during suspend/resume cycle to ensure handling of wakeup
interrupts (i.e. RTC wake alarm) after max8997_resume(). This way it can
be properly handled when I2C bus is finally available. This pattern is
also used in other MAX PMIC MFD drivers.

mfd: max8997: Enale irq-wakeup unconditionally

2018-10-23T07:58:34+00:00

IRQ wake up support for MAX8997 driver was initially configured by
respective property in pdata. However, after the driver conversion to
device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD
drivers initialized from device-tree assume that they can be an irq wakeup
source, so enable it also for MAX8997. This fixes support for wakeup from
MAX8997 RTC alarm.

mfd: max8997: Make it explicitly non-modular

2016-06-29T09:14:30+00:00

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_MAX8997
drivers/mfd/Kconfig:    bool "Maxim Semiconductor MAX8997/8966 PMIC Support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
