Well, I could be convinced to take patches that are a little better
documented (i.e., have a little better commit descriptions), if they
fix real issues. If you're going to add device tree properties, though,
you need a DT binding doc. And the refactoring to a platform driver
should be pretty trivial, but it's not an absolute blocking requirement,
since the driver's already in mainline.

BTW, one issue with the current driver, if you're going to add a DT
binding doc: you currently require the "gen_nand" string, like this, in
your openwrt DTS(I) files:

	nand-parts at 0 {
		compatible = "gen_nand", "lantiq,nand-xway";
		...
	};

That's not an acceptable binding, and that's where refactoring the
driver would help too.
