+STMPE Touchscreen
+----------------
+
+Required properties:
+ - compatible: "st,stmpe-ts"

You shouldn't be specifying a compatible string in the DT.

+Example:
+
+     stmpe_touchscreen {
+             compatible = "st,stmpe-ts";

This needs to be removed.

Copying my earlier reply from stmpe-gpio patch for others to know
what i have to say on this :)

I believe these are required by the code you wrote in mfd-core.c

        if (parent->of_node && cell->of_compatible) {
                for_each_child_of_node(parent->of_node, np) {
                        if (of_device_is_compatible(np, cell->of_compatible)) {
                                pdev->dev.of_node = np;
                                break;
                        }
                }
        }

This matches compatible of child node with compatible of cell. And that's
why you have added that in your keypad mappings as well.

Yes, you're right. Please ignore this comment.
