Subject: Fixed PHY and MPC832x based boards don't work
Date: Sun, 13 May 2007 16:39:30 +0200 [thread overview]
Message-ID: <1179067171.20638.48.camel@gentoo-jocke.transmode.se> (raw)
Trying to make the Fixed PHY work under my 832x based board on current
linus tree without success. Earlier kernels with custom PHY code for
ucc_geth work without any special tricks.
If I enable the FIXED_MII_100_FDX option I get:
ls bus/mdio_bus/devices/
fixed@100:1@
but ucc_geth wants its PHYs under
ls -l bus/of_platform/devices/*phy*
lrwxrwxrwx 1 root root 0 May 12 17:32 bus/of_platform/devices/ethernet-p
hy.1 -> ../../../devices/e0100000.qe/e0102320.mdio/ethernet-phy.1/
lrwxrwxrwx 1 root root 0 May 12 17:32 bus/of_platform/devices/ethernet-p
hy.3 -> ../../../devices/e0100000.qe/e0102320.mdio/ethernet-phy.3/
lrwxrwxrwx 1 root root 0 May 12 17:32 bus/of_platform/devices/fixed-phy.
2 -> ../../../devices/e0100000.qe/e0102320.mdio/fixed-phy.2/
These are 3 PHYs I just added in the DTS tree:
mdio@2320 {
#address-cells = <1>;
#size-cells = <0>;
reg = <2320 18>;
device_type = "mdio";
compatible = "ucc_geth_phy";
phy1: ethernet-phy@18 {
linux,phandle = <212000>;
reg = <18>; // 24
device_type = "ethernet-phy";
interface = <3>; //ENET_100_MII
};
phy2: fixed-phy@64 {
linux,phandle = <212001>;
reg = <d#100>;
device_type = "ethernet-phy";
};
phy3: ethernet-phy@19 {
linux,phandle = <212002>;
interrupt-parent = <700>;
interrupts = <12 2>;
reg = <19>; // 25
device_type = "ethernet-phy";
interface = <3>; //ENET_100_MII
};
};
How do I add a fixed PHY so that ucc_geth finds it?
