Subject: [PATCH 2/2] ARM: at91: pm: use of_device_id array to find the proper shdwc node
Date: Wed, 11 Dec 2019 13:04:08 +0200	[thread overview]
Message-ID: <1576062248-18514-3-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1576062248-18514-1-git-send-email-claudiu.beznea@microchip.com>

Use of_device_id array to find the proper shdwc compatibile node.
SAM9X60's shdwc changes were not integrated when
commit eaedc0d379da ("ARM: at91: pm: add ULP1 support for SAM9X60")
was integrated.

Fixes: eaedc0d379da ("ARM: at91: pm: add ULP1 support for SAM9X60")
