[RFC] [PATCH 0/3] of: allow to support irq domain register as platform_device for platform_device

[Jean-Christophe PLAGNIOL-VILLARD <plagnioj-sclMFOaUSTBWk0Htik3J/w@public.gmane.org>]

Hi,

	Today in the current of implementation we populate all the ressources
	at of_platform_populate time. But this leed to a chicken-egg dilemat
	some the irq present in DT are from platform_device too. And you can
	not resolve them as of_platform_populate. So delay the populate of irq
	at platform_drv_probe.

	And if the irq_domain is not yet present just defer the probe (GPIO as example)

	we still have one issue is that the gpio irq provide by DT need to have
	the gpio requested and configured which I'll fix later by handling this automatically
	by a gpio_irq_chip and dorp this from every drivers
