Can you please add the usual hardware and installation info?
For examples see other commits that added support for a specific device.

Betreff: [OpenWrt-Devel] [PATCH] Support for Edimax EW-7476RPC
Hi Cezary,
In addition to the EW-7476RPC, I added support for the EW-7478AC as you suggested. I could not test that image, but at least it compiles.
I fixed all of your comments as suggested, however left it at mediatek,rtl8211e-reset = "yes"; I believe there are other similar devices from Edimax out there with the Realtek chip, and possibly a different GPIO line. Then something like mediatek,rtl8211e-reset = <39>; could be used.
Birger
Here comes the patch:
