TI: DaVinci: GPIO header file and definitions
Some DaVinci SOC's use GPIOs to enable EMAC and DM9000. This patch adds some definitions for GPIO registers and also adds structures for GPIO. A separate header file is being added so that in future we can have a DaVinci GPIO driver similer to OMAP. Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com> Acked-by: Tom Rix <Tom.Rix@windriver.com>
