net: ethernet: ixp4xx: Standard module init

2020-02-24T07:38:04Z

[ Upstream commit c83db9ef5640548631707e8b4a7bcddc115fdbae ] The IXP4xx driver was initializing the MDIO bus before even probing, in the callbacks supposed to be used for setting up the module itself, and with the side effect of trying to register the MDIO bus as soon as this module was loaded or compiled into the kernel whether the device was discovered or not. This does not work with multiplatform environments. To get rid of this: set up the MDIO bus from the probe() callback and remove it in the remove() callback. Rename the probe() and remove() calls to reflect the most common conventions. Since there is a bit of checking for the ethernet feature to be present in the MDIO registering function, making the whole module not even be registered if we can't find an MDIO bus, we need something similar: register the MDIO bus when the corresponding ethernet is probed, and return -EPROBE_DEFER on the other interfaces until this happens. If no MDIO bus is present on any of the registered interfaces we will eventually bail out. None of the platforms I've seen has e.g. MDIO on EthB and only uses EthC, there is always a Ethernet hardware on the NPE (B, C) that has the MDIO bus, we just might have to wait for it.

ARM: ixp4xx: Move IXP4xx QMGR and NPE headers

2019-04-23T14:02:15Z

This moves the IXP4xx Queue Manager and Network Processing Engine headers out of the include path as that is incompatible with multiplatform. Signed-off-by: Linus Walleij

ARM: ixp4xx: Add device tree boot support

2019-04-23T14:02:15Z

This adds a minimal support for booting IXP4xx systems from device tree. We have to add hacks to the QMGR, NPE and notably also ethernet and watchdog drivers so that they don't crash the platform: these drivers are unconditionally starting to grab regions of statically remapped IO space with no concern of the device model or other platforms. We will go in and properly fix these drivers as we go along but for now this hack gets us to a place where we can start working on proper device tree support for these platforms.

net: ixp4xx_eth: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
