* Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x Controller Required properties: - compatible : Should be "smsc,lan", "smsc,lan9115" - reg : Address and length of the io space for SMSC LAN - interrupts : Should contain SMSC LAN interrupt line - interrupt-parent : Should be the phandle for the interrupt controller that services interrupts for this device - phy-mode : See ethernet.txt file in the same directory Optional properties: - reg-shift : Specify the quantity to shift the register offsets by - reg-io-width : Specify the size (in bytes) of the IO accesses that should be performed on the device. Valid value for SMSC LAN is 2 or 4. If it's omitted or invalid, the size would be 2. - smsc,irq-active-high : Indicates the IRQ polarity is active-high - smsc,irq-push-pull : Indicates the IRQ type is push-pull - smsc,force-internal-phy : Forces SMSC LAN controller to use internal PHY - smsc,force-external-phy : Forces SMSC LAN controller to use external PHY - smsc,save-mac-address : Indicates that mac address needs to be saved before resetting the controller Examples: lan9220@f4000000 { compatible = "smsc,lan9220", "smsc,lan9115"; reg = <0xf4000000 0x2000000>; phy-mode = "mii"; interrupt-parent = <&gpio1>; interrupts = <31>; reg-io-width = <4>; smsc,irq-push-pull; };
