Without this patch you will get an error "gpio-export probe deferral
not supported" when you try to export i2c expander gpio pins.
gpio-export is probed long before i2c-bus and i2c expander are created
and it doesn't retry it so none pins are exported.

Use of_mdiobus_register() to pass the ethernet phy node to the phy
drivers. This is needed for the at8030 phy driver which needs to know
the GPIO which is connected to the ar8030 reset pin.
This driver expects a child in gsw/etop node named "mdio-bus", which has
the ethernet phys defined:
&gsw {
phy-mode = "rmii";
phy-handle = <&phy0>;
mtd-mac-address = <&ath9k_cal 0xa91>;
mtd-mac-address-increment = <(-2)>;
mdio-bus {
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
phy0: ethernet-phy@0 {
reg = <0>;
reset-gpios = <&gpio 34 GPIO_ACTIVE_LOW>;
};
};
};
Fallback to mdiobus_register() if no mdio-bus child node exists. This
way we don't need to touch all xway dts files, for which we don't know
the actual address on the mdio bus.

To keep the status of a LED connected to the stp during boot, the get
callback is required. If the callback is missing and the LED default
state is set to keep in the devicetree, the gpio led driver errors out
during load.

Check if the GPIO is valid (or set at all). If no GPIO is set in the
devicetree, a gpiolib related kernel warning + stacktrace is shown during
boot and gpio-export reports GPIOs as exported albeit none really is.

When upstream kernel introduced commit c55fa3cccbc2c672e7f118be8f7484e53a8e9e77

The correct solution is to drop our ifx_atm_alloc_tx replacement hack
entirely and let the kernel do its thing.
In reality neither pppoatm or BR2684 interfaces actually hit this code,
so the incorrect integration would only be noticed with direct socket
calls which we are unaware of a use-case.
This is not the solution to pppoatm vc-mux failing to work which started
the whole investigation, but let's fix it up anyway.

Backport patch accepted upstream which removes the reset asserts of the
xrx200 gphy driver on reboot/remove.
While doing a global software reset, these bits are not cleared and let
some bootloader fail to initialise the GPHYs. The bootloader don't expect
these bits to be set, as they aren't during power on.
The asserts were a workaround for a wrong syscon-reboot mask. With a mask
set which includes the GPHY resets of the first reset register, the
resets of the second reset register arn't required any more.

On danube the USB0 registers are at 1e101000 similar to all other lantiq
SoCs.
On Danube and AR9 the USB core is connected to the AHB bus, hence we need

Add a custom xrx200 ethernet phy compatible to load the firmware matching
the vr9 revision without specifing an expected revision.
We have quite a few boards in the tree were later produced ones are using
a more recent vr9. It is impossible to distinguish which revision of the
vr9 is used without opening the case and removing a heatsink for some of
them.

This reverts kernel commit 1eed40043579 ("MIPS: smp-mt: Use CPU interrupt
controller IPI IRQ domain support"). With the patch applied, the kernel
hangs during boot if SMP is active.
The Lantiq IRQ controller gets registered first and it directly handles
the MIPS native SW1/2 and HW0 - HW5 IRQs. It looks like this controller
already registers IRQ 0 - 7 and the generic driver only gets the following
IRQs starting later.
The upstream discussion can be found at
