+[PATCH] Add support for FusionHDTV DVB-T NANO 2 / Dual Digital 4
+
+Firmware required:
+
+Mirror 1: http://konstantin.filtschew.de/v4l-firmware/
+
+Mirror 2: http://www.tuxamito.com.es/em2880/
+
+This patch is for users, and NOT meant to be merged into the kernel.
+
+For AU support, apply Rogers patch afterwards:
+http://linuxtv.org/~mkrufky/pending/xc/dd4.au.patch
