Subject: [PATCH] MIPS: Octeon: mark GPIO controller node not populated IRQ, init.
Date: Thu, 25 Aug 2016 16:22:26 -0500	[thread overview]
Message-ID: <422712ab-4b0d-2b6d-4600-b917c2d327a9@cavium.com> (raw)

We clear the OF_POPULATED flag for the GPIO controller node, otherwise
the GPIO lines used by the MMC driver are never probed.

Fixes: 15cc2ed6dcf9 ("of/irq: Mark initialised interrupt controllers as populated")
