252197f014 apm821xx: provide legacy interrupts for PCIe in DT
Devices with PCIe-Switches like the WNDR4700, MR24 and WNDAP660
need to have the interrupts property specified in the device-tree
for the legacy pci interrupt signaling method to work.

If the proper interrupt value is not specified, the default INTA
IRQ 12 is taken for all devices. This is especially bad, if the
device is setup to use INTC, because these interrupts will not
be serviced.

Russell Senior reported his experience on the MR24:
"The symptom is client devices can't see the beacons.
Wifi ifaces appear, can scan and hear other networks,
but clients can't see the MR24's SSIDs."

(The interrupts-property on the WNDAP620 was optional since it
uses INTA by default. Likewise the MX60W is in the same category)

971f31bedc apm821xx: fix bogus key-presses on boot
"There are often transient line events when
the system is powered up and initialized and it
is often necessary for the gpio_chip driver to
clear any interrupt flags in hardware before
setting up the gpio chip, especially the
irqchip portions of it."
<http://lists.infradead.org/pipermail/openwrt-devel/2019-June/017630.html>

This patch adds a fix for the APM821XX's interrupt
controller to clear any bogus pending toggled
interrupts that happens on various APM821XX boards
on boot.

The patch also changes the debouce-interval from the
default 5ms debounce interval to 60ms all around.
The default setting caused on occasions that the button
state became stuck in a pressed state, even though the
button was released.

cbb44f6ed7 apm821xx: dts: Unify naming of gpio-led nodes
In DTS Checklist[1] we're now demanding proper generic node names, as
the name of a node should reflect the function of the device and use
generic name for that[2]. Everybody seems to be copy&pasting from DTS
files available in the repository today, so let's unify that naming
there as well and provide proper examples.

This patch fixes some of the dtc warnings:

MR24:
"reg" property in [...]mdio/phy@1 has invalid length (4 bytes)
Node [...]button@1 has a unit name, but no reg property
Relying on default #address-cells value for [...]phy@1
Relying on default #size-cells value for [...]phy@1

MX60(W):
Node [..]nand/all has a reg or ranges property, but no unit name
Node [..]button@1 has a unit name, but no reg property

1adeecf0d3 apm821xx: dts: rename devices dts files to include the manufacturer
This patch rename all the DT source files in order to
match upstream's "manufacturer-device.dts" format.

Please note that the DEVICE_DTB isn't changed. This is
because the u-boot of the MyBook Live defines the
fdt_file variable to be "apollo3g/apollo3g.dtb".
