Subject: [PATCH v2 4/7] ARM: dts: Add base DT for NXP LPC18xx
Date: Mon, 27 Apr 2015 23:04:52 +0200	[thread overview]
Message-ID: <1430168695-21248-5-git-send-email-manabian@gmail.com> (raw)
In-Reply-To: <1430168695-21248-1-git-send-email-manabian@gmail.com>

NXP LPC18xx/43xx SoCs are very similar devices and should be able to
share a common base (lpc18xx.dtsi). Diffences between the devices are
put in a dtsi which is specific to that device.
