mfd: mt6397: IRQ domain should initialize before mfd_add_devices()

2016-05-09T07:20:22+00:00

Some sub driver like RTC module need irq domain from parent to create
irq mapping when driver initialize. so move mt6397_irq_init() before
mfd_add_devices().

mfd: mt6397: Use devm_mfd_add_devices() for mfd_device registration

2016-04-19T06:55:40+00:00

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.

mfd: mt6397: Add platform device ID table

2016-03-16T08:50:32+00:00

The platform bus_type .match callback attempts to match the platform device
name with an entry on the .id_table if provided and fallbacks to match with
the driver's name if a table is not provided.

Using a platform device ID to match is more explicit, allows the driver to
support more than one device and also the MODULE_DEVICE_TABLE macro can be
used to export the module aliases information instead of the MODULE_ALIAS.

MT6323 has the INT_CON and INT_STATUS located at a different position.
Make the registers locations configurable.

mfd: mt6397: Implement wake handler and suspend/resume to handle wake up event

2015-08-11T14:09:11+00:00

Implement .irq_set_wake() to get who is wakeup source and setup on suspend/reumse. Enable
mt6393_irq as wake up source properly to pinctrl by enable_irq_wake()/enable_irq_wake().

mfd: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

2015-08-11T14:09:06+00:00

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.

Do the same change to avoid the pattern "irq_get_chip_data(data->irq)".

mfd: Kill off set_irq_flags usage

2015-08-11T14:09:01+00:00

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.
