Subject: [PATCH 1/3] ARM: dts: am335x: introduce new "stripped" common.dtsi for PBL use
Date: Mon, 20 Aug 2018 11:57:34 +1000 [thread overview]
Message-ID: <20180820015736.6680-1-marc@cpdesign.com.au> (raw)
From: Marc Reilly <marc@cpdesign.com.au>
This moves am335x-bone-common.dts to include a "stripped" version of the
bone-common .dtsi (which is initially copied from the present one.)
This is in preparation for updating the bone-common .dtsi to use the
kernel version, which introduces some nodes which rely on clocks etc
which are removed from the "stripped" .dtsi files.
