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.
