Those tests check: - the ability for a phy-user to get a phy based on its name or its index - the ability of a phy device (provider) to manage multiple ports - the ability to perform operations on the phy (init,deinit,on,off) - the behavior of the uclass when optional operations are not implemented Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>
