To: broonie, gregkh, sameo; +Cc: swarren, linux-kernel, Laxman Dewangan
Implement irq support of tps65910 with regmap irq framework
in place of implementing locally.
This reduces the code size significantly and easy to maintain.

- * the physical IRQ will be handled again if another interrupt is
- * asserted while we run - in the normal course of events this is a

From: Laxman Dewangan @ 2012-10-09 11:28 UTC (permalink / raw)
To: broonie, gregkh, sameo; +Cc: swarren, linux-kernel, Laxman Dewangan
In place of implementing the irq support in separate file,
moving implementation to main mfd file.
The irq files only contains the table and init steps only
and does not need extra file to have this only for this
purpose.

Add sub devices of tps65910 after all initialization like interrupt,
clock etc. is done. This will make sure that require data gets
initialized properly before sub devices probe's get called.

Add API regmap_irq_get_irq_domain() for getting the
irq domain from regmap irq.
The irq domain created on result of regmap_add_irq_chip()
from driver.
This API is useful in mfd driver when driver add mfd sub devices.
The sub devices IRQs can be passed through IORESOURCE_IRQ and it
need to be mapped properly with device irq domain. The
mfd_add_devices() creates mapping when adding sub devices and for
this it is require to have irq domain.

When adding the sub device "tps65910-rtc", is it passed the
IO resource IRQ for the interrupt number.
This interrupt needs to map in the device irq domain. Pass
the irq domain of device in mfd_add_devices() so that proper
irq mapping can be done when adding the sub device RTC.
