Subject: [PATCH v2 7/8] ARM: stm32mp: ddrctrl: add deep-probe support
Date: Wed, 30 Sep 2020 10:47:15 +0200	[thread overview]
Message-ID: <20200930084716.4200-8-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20200930084716.4200-1-m.felsch@pengutronix.de>

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

Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>

v2:
- convert to of_devices_ensure_probed_by_dev_id()
- drop use-less deep-probe include
