netdev: driver: ethernet: Add TI CPSW driver
This patch adds support for TI's CPSW driver. The three port switch gigabit ethernet subsystem provides ethernet packet communication and can be configured as an ethernet switch. Supports 10/100/1000 Mbps. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Sriramakrishnan A G <srk@ti.com> Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S.
