However, those two informations are completely -unrelated. - -This patch decouples them. The PHY id of fixed PHYs is hardcoded to be -0x0. Ideally, a really reserved value would be nicer, but there -doesn't seem to be an easy of making sure a dummy value can be -assigned to the Linux kernel for such usage. - -The PHY address remains passed by the caller of phy_fixed_add(). - -Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> -Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> -Tested-by: Florian Fainelli <f.fainelli@gmail.com> -Signed-off-by: David S.
