[PATCH] irqchip/irq-imx-gpcv2: Clear OF_POPULATED flag

From: Andrey Smirnov
Date: Tue Apr 11 2017 - 12:48:52 EST


Clear OF_POPULATED flag, so that GPC power domain driver[1] can be
bound to "gpc" node as well.

Marc:

You've expressed you disagreement (in [thread]) for adding generic
infrastructure to perform this kind of trickery because of its
DT-specific nature. Any chance this, more contained version of it, is
acceptable?

Thanks,
Andrey Smirnov
