Subject: [PATCH 1/5] ARM: am335x: phyFLEX-AM335x: Split DT and add MLO DT
Date: Wed, 4 Feb 2015 15:00:49 +0100 [thread overview]
Message-ID: <1423058453-17012-1-git-send-email-w.egorov@phytec.de> (raw)
To support different module variants, this patch splits the phyFLEX DT
in dts and dtsi.
And we are also adding a DT for the MLO, which has all bootable devices
disabled. The bootsource is checked in the board file and only the needed
device is enabled and registered.
