From b9b2909093ede6f0cea2beff201264f431504de3 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Wed, 21 Feb 2018 16:38:06 +0000 Subject: watchdog: imgpdc: Drop METAG dependency Now that arch/metag/ has been removed, remove the METAG dependency from the IMG IR device driver. The hardware is also present on MIPS SoCs so the driver still has value.
