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.

mfd: max77686: Add max77802 to I2C device ID table

2016-03-16T08:50:40+00:00

The max77686 MFD driver supports both the Maxim 77686 and Maxim 77802
PMICs but only the OF device table contains entries for both devices.

The max77802 entry is missing in the I2C device ID table which isn't
a problem currently since the driver only supports DT but it will be
needed if the driver is changed to be built as a module since the I2C
core always reports a I2C modalias uevent so auto-load will not work.

mfd: max77686: Export OF module alias information

2016-03-16T08:50:39+00:00

When the device is registered via OF, the OF table is used to match the
driver instead of the I2C device ID table but the entries in the latter
are used as aliasses to load the module if the driver was not built-in.

This is because the I2C core always reports an I2C module alias instead
of an OF one but that could change so it is better to always export it.

rtc: max77686: move initialisation of rtc regmap, irq chip locally

2016-03-14T16:08:13+00:00

To make RTC block of MAX77686/MAX77802 as independent driver,
move the registration of i2c device, regmap for register access
and irq_chip for interrupt support inside the RTC driver.
Removed the same initialisation from MFD driver.

Having this change will allow to reuse this driver for different
PMIC/devices from Maxim Semiconductor if they kept same RTC IP on
different PMIC. Some of examples as PMIC MAX77620, MAX20024 where
same RTC IP used and hence driver for these chips will use this
driver only for RTC support.

mfd: max77686: do not set i2c client data for rtc i2c client

2016-03-14T16:08:12+00:00

There is different RTC I2C address for RTC block in MAX77686.
Driver is creating dummy i2c client for this address to access
the register of this IP block.

As there is no call to i2c_get_clientdata() for rtc_i2c client,
there is no need to store pointer and hence removing the call
to set client data for rtc i2c client.
