Subject: [PATCH] fixup! ARM: stm32mp: add basic DDR controller driver
Date: Wed, 13 Nov 2019 10:28:48 +0100	[thread overview]
Message-ID: <20191113092848.9207-1-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20191112091956.26628-8-a.fatoum@pengutronix.de>

While Linux doesn't have a device node for the DDR controller,
U-Boot and ARM TF-A do and they both use the st,stm32mp1-ddr compatible,
which encompasses both DDRCTRL and DDRPHY. Follow suit.
