Add pinmux configurations for RGMII based CPSW ethernet to AM335x EVMsk. Default mode is nothing but the values required for the module during active state. With this configurations module is functional as expected. Sleep mode is nothing but the values required for the module during inactive state. The pins are configured to its reset state to optimize energy usage for the pins for the suspend/resume cycle Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: Benoit Cousson <benoit.cousson@linaro.org>
