Currently, the UniPhier pinctrl driver itself is a syscon, but it turned out much more reasonable to make it a child node of a syscon because our syscon node consists of a bunch of system configuration registers, not only pinctrl, but also phy, and misc registers. It is difficult to split the node. This commit allows to migrate to the new DT structure. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
