lib: cordic: Move cordic macros and defines to header file

2018-11-29T15:30:48+00:00

Now that these macros are in header file, we can eventually clean up the duplicate macros present in the drivers that utilize the same cordic algorithm implementation. Also add CORDIC_ prefix to nonprefixed macros. Reviewed-by: Arend van Spriel Signed-off-by: Priit Laes Acked-by: Larry Finger Signed-off-by: Kalle Valo

lib: cordic: add library module providing cordic angle calculation

2011-06-03T19:01:07+00:00

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.
