Subject: [PATCH 17/18] ARM: stm32mp: ddrctrl: add deep-probe support
Date: Mon, 28 Sep 2020 17:50:40 +0200	[thread overview]
Message-ID: <20200928155041.32649-18-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20200928155041.32649-1-m.felsch@pengutronix.de>

In case of deep-probe we have to ensure that the memory device is
available after the mem_initcall().
