From 34fecff87e1ec3d34f07b0894713faff2e392cb4 Mon Sep 17 00:00:00 2001
From: Sylvain Munaut <tnt@246tNt.com>
Date: Sat, 25 Jan 2014 21:25:53 +0100
Subject: blocks: Add a new rotator_cc block to perform frequency shifting
It internally uses the rotator.h helper that was already present,
which in turn makes uses of VOLK rotator kernel
