Subject: [PATCH 2/4] ARM: dts: imx6: Use gpc for FEC interrupt controller to fix wake on LAN.
Date:   Tue, 17 Mar 2020 17:50:04 +0100
Message-Id: <1584463806-15788-3-git-send-email-martin.fuzzey@flowbird.group>
In-Reply-To: <1584463806-15788-1-git-send-email-martin.fuzzey@flowbird.group>

Precedence: bulk

In order to wake from suspend by ethernet magic packets the GPC must be
used as intc does not have wakeup functionality.

But the FEC DT node currently uses interrupt-extended, specificying intc,
this breaking WoL.

This problem is probably fallout from the stacked domain conversion as
intc used to chain to GPC.

So replace "interrupts-extended" by "interrupts" to use the default
parent which is GPC.

Fixes: b923ff6af0d5 ("ARM: imx6: convert GPC to stacked domains")
