Changes in v4: - Either register a mdio node or phy child nodes - Check for valid phy node before registering the phy node This is like the kernel does it - Also recognize compatible="ethernet-phy-id*" as PHY's again like the kernel, but with a simpler implementation, as we do not try to read the actual phy_id Changes in v3: - Consider the v3 a new implmentation - almost nothing was left from v2. Thus also invalidate any former review - sorry. - Dropped the need for the mdio {} node, as this node is only used when there is dedicated HW support for the mdio. - Added so PHY child nodes to ethernet nodes are registered, and as part of registration the PHY nodes are reset if the reset-gpios property is present. - Further dropped that the parsed info is stored in the bus, as we only do reset once, thus there is no need to save the info from the DT - Futher dropped helper function to reset. They was not needed - Named the gpio with the name of the PHY node in the DT. This makes it unique and easier to recognize. Changes in v2: - Added patch to enable Davicom PHY on at91sam9263ek - evaluation kit - Fix so we do reset before comunicating with the PHY - Rename to mdio_reset() - Reference correct binding file in commit log (mdio.txt) - Tested on at91sam9263ek The at91sam9263ek kit do not require the reset like my proprietary board, so no DT changes required Intro: The following patches was necessary to get networking operational on my proprietary target. The target is at91sam9263 based with a Davicom PHY. The Davicom PHY is a straight copy form the Linux kernel with the interrupt routine removed and minor adjustments to the rest. The davicom PHY would not work until it had seen a reset cycle - which I think may be an artifact of the board design. To fix the reset issue I have implemented support for the reset-gpios binding (see net/phy.txt bindings). A minimal implmentation was done, just enough to get my target running. I could have implemented something in macb - but I preferred the more generic solution. Also included are a patch that for the at91sam9263ek evaluation board. The patch adds several extra tools that are usefull for testing, and enable the Davicom PHY.
