+Subject: [PATCH] arm/ixp4xx: Rename FREQ macro to avoid collisions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+FREQ is a ridiculously short name for a platform-specific macro in a
+generic header, and it now conflicts with an enumeration in the
+gspca/ov519 driver.
+
+Also delete conditional reference to ixp4xx_get_board_tick_rate()
+which is not defined anywhere.
