Subject[PATCH] irqchip/irq-imx-gpcv2: Clear OF_POPULATED flag
Date
Clear OF_POPULATED flag, so that GPC power domain driver[1] can be
bound to "gpc" node as well.

You've expressed you disagreement (in [thread]) for adding generic

DT-specific nature. Any chance this, more contained version of it, is
acceptable?
