Subject: [PATCH 16/19] ARM: boards: mx6-sabrelite: add deep-probe support
Date: Fri, 25 Jun 2021 09:25:37 +0200 [thread overview]
Message-ID: <20210625072540.32717-17-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210625072540.32717-1-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.
