Now that a "regulators" child is accepted by the controller binding, the
debugfs show routine must be explicitly limited to "sram" children.

You should not rely on node names. They can change in DTS. Why do you
need to test for the name?

Ah, it is not a device node but a child property, right? In such case,
it's of course fine.

It is a child node.

The device node names could change and should not be considered ABI (at
least I hope should not...).

The node names are limited by patternProperties in the controller binding. I can
check the child nodes for compatibility with "mmio-sram" if that is better.
