As pointed by Rob, CRU is a kind of block that can't be guaranteed to have everything exposed as subnodes. It's a set of various registers that aren't tied to any single device. It could be described much more accurately as MFD (Multi-Function Device). Some hardware blocks may indeed want to access a register or two of the CRU which requires describing it as the "syscon". While at it replace exmple node name with the standard "pinctrl" (also pointed out by Rob). Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
