Subject: [PATCH v1 02/12] ARM: dts: stm32mp: factor out common DK nodes into dtsi
Date: Mon, 17 Jun 2019 17:07:41 +0200 [thread overview]
Message-ID: <20190617150751.3421-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20190617150751.3421-1-a.fatoum@pengutronix.de>
The DK2 appears to be just the DK1 with a display, thus factor out the
barebox-specifics into a new stm32mp157a-dk1.dtsi, which we can include
in both device trees after including the upstream device tree.
As the updated device tree introduced new nodes, the now duplicates
(ðernet0, &uart4, /chosen and /aliases) are dropped from the barebox
device as part of this commit as well.
