drivers: net: davinci_mdio: restore mdio clk divider in mdio resume
During suspend resume cycle all the register data is lost, so MDIO clock divier value gets reset. This patch restores the clock divider value. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
