| |
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.
