From 10f8113ecb76eea72f96c7cfb72d7fed7c282565 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Tue, 31 May 2011 11:22:16 +0200 Subject: lib: cordic: add library module providing cordic angle calculation The brcm80211 driver in the staging tree has a cordic function to determine cosine and sine for a given angle. Feedback received from John Linville suggested that these kind of functions should be made available to others as a library function in the kernel tree. The b43 driver also has a cordic angle calculation implemented. Cc: linux-kernel@vger.kernel.org Cc: linux-wireless@vger.kernel.org Cc: "John W.
