Subject: [PATCH 15/17] ARM: boards: mx6-sabrelite: add deep-probe support
Date: Thu,  6 May 2021 11:28:59 +0200
Message-ID: <20210506092901.25461-16-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210506092901.25461-1-s.hauer@pengutronix.de>

From: Marco Felsch <m.felsch@pengutronix.de>

Convert to board driver and explicitly request the required gpio
resources instead of relying on their existence based on the initcall
level.
