Subject: [PATCH 5/5] ARM: dts: imx28-cfa10049: Move i2cmux out of bus node
Date: Wed, 27 Dec 2017 12:04:38 -0200 [thread overview]
Message-ID: <1514383478-32544-5-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1514383478-32544-1-git-send-email-festevam@gmail.com>
From: Fabio Estevam <fabio.estevam@nxp.com>
Move i2cmux node from soc node to root node.
i2cmux node does not have any register properties and thus shouldn't be
placed on the bus.
This fixes the following build warnings with W=1:
arch/arm/boot/dts/imx28-cfa10049.dtb: Warning (simple_bus_reg): Node /apb at 80000000/apbx at 80040000/i2cmux missing or empty reg/ranges property
Cc: Maxime Ripard <maxime.ripard@free-electrons.com>
