Subject: [PATCH] arm64: dts: meson: Switch simple-mfd and syscon order
Date: Thu, 26 Jul 2018 16:13:58 +0200 [thread overview]
Message-ID: <1532614438-7207-1-git-send-email-narmstrong@baylibre.com> (raw)
The order between "syscon" and "simple-mfd" is important because in these
particular cases, the node needs to be first a "simple-mfd" to expose
it's sub-nodes, and later on a "syscon" to permit other nodes to access
this register space through the "syscon" mechanism.
Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>

This also has a consequence for U-Boot since the U-Boot DM is much simpler
and can only associate a single device to a node, thus here we want these
nodes to be an mfd bus to be able to probe the sub-nodes.
