netdev/of/phy: New function: of_mdio_find_bus().

2012-05-08T02:58:09Z

Add of_mdio_find_bus() which allows an mii_bus to be located given its associated the device tree node. This is needed by the follow-on patch to add a driver for MDIO bus multiplexers. The of_mdiobus_register() function is modified so that the device tree node is recorded in the mii_bus. Then we can find it again by iterating over all mdio_bus_class devices. Because the OF device tree has now become an integral part of the kernel, this can live in mdio_bus.c (which contains the needed mdio_bus_class structure) instead of of_mdio.c.

of/mdio: Add support function for Ethernet fixed-link property

2009-07-22T16:27:18Z

Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet device drivers. The "OF MDIO rework" patches removed most of the support. Instead of re-adding fixed-link stuff to the drivers, this patch adds a support function for parsing the fixed-link property and obtaining a dummy phy to match. Note: the dummy phy handling in arch/powerpc is a bit of a hack and needs to be reworked. This function is being added now to solve the regression in the Ethernet drivers, but it should be considered a temporary measure until the fixed link handling can be reworked.

openfirmware: Add OF phylib support code

2009-04-27T09:53:47Z

Add support for parsing the device tree for PHY devices on an MDIO bus. Currently many of the PowerPC ethernet drivers are open coding a solution for reading data out of the device tree to find the correct PHY device. This patch implements a set of common routines to: a) let MDIO bus drivers register phy_devices described in the tree, and b) let MAC drivers find the correct phy_device via the tree.
