Stephen Warren reported the recent commit 78506f22 (add support for
extended FIFO-size of PL011-r1p5) breaks the serial port on the
BCM2835 ARM SoC.

A UART compatible with the ARM PL011-r1p5 should have 32-deep FIFOs.
The BCM2835 UART just looks like an ARM PL011-r1p5, but has 16-deep
FIFOs just like PL011-r1p4 or earlier revisions. As a workaround for
this compatibility issue, this patch overrides the HW UART periphid
register values with the actually compatible UART periphid 0x00241011
(r1p3 or r1p4).

The assignment of IRQ for the SMC91x ethernet adapter had two
problems making it non-working:

- It was not put into the ethernet device node. Let's do this
  by using the board-specific overlay, so we can make other
  overlays on other Nomadik boards.

- The IRQ number was actually completely wrong, this was the
  number for NHK8815, not S8815.

After this ethernet starts working on the USB S8815.

Since 82a68267 ('ARM: dts: mvebu: Convert all the mvebu files to use
the range property') all the device nodes of Armada 370/XP are under a
common 'ranges' property that translates the device register addresses
into their absolute address, thanks to the base address of the
internal register space.

However, beyond just the register areas, there are also PCIe I/O and
memory regions, whose addresses should be properly translated. This
patch fixes the Armada 370 and XP ranges property to take PCIe into
account properly.

Commit ff5c9059 (ARM: dts: OMAP3+: Correct gpio #interrupts-cells
property) updated the number of interrupt cells required for configuring
gpios as interrupts for other devices (such as ethernet controllers).
This update allowed the interrupt type (edge, level, etc) to be
configured via device-tree (as described in the
Documentation/devicetree/bindings/gpio/gpio-omap.txt).

This broke ethernet support on the OMAP4 SDP board that defines a gpio
as the ethernet IRQ because the interrupt type (level, edge, etc) was
not getting configured correctly. This board use the ks8851 ethernet
chip which has an active low interrupt. Fix this by defining the gpio
interrupt as active-low in the device-tree binding.

Please note that the OMAP4-VAR-SOM also uses the same ethernet
controller and it is expected it will have the same problem. So the
same fix is also applied to this board.

The arbitrated bus is numbered 104 simply as a convenience to make it
easier for people poking around to guess that it might have something
to do with the physical bus 4.

This change makes the rtc on the exynos5250 and 5440 disabled by
default to match exynos4.

Ever since the common clock framework came in, exynos5250 boards
have dumped lots of warnings in the boot log. It turns out that
we don't see those on exynos4 since the rtc is disabled by default.
While we need to get to the bottom of the problems with the RTC,
it still makes sense to have the default state of the RTC on exynos
boards match.

For the record, warnings look like this:
