a894c6dd56 ARM: dts: arm: Fix SP805 clocks
The SP805 binding sets the name for the actual watchdog clock to
"wdog_clk" (with an underscore).

Change the name in the DTs for ARM Ltd. platforms to match that. The
Linux and U-Boot driver use the *first* clock for this purpose anyway,
so it does not break anything.

For MPS2 we only specify one clock so far, but the binding requires
two clocks to be named.

In practice, Linux would pick a clock named "apb_pclk" for the bus
clock, and the Linux and U-Boot SP805 driver would use the first clock
to derive the actual watchdog counter frequency. So since currently both
are the very same clock, we can just double the clock reference, and add
the correct clock-names, to match the binding.

34a4591871 ARM: dts: arm: Fix SP804 users
The SP804 DT nodes for Realview, MPS2 and VExpress were not complying
with the binding: it requires either one or three clocks, but does not
allow exactly two clocks.

Simply duplicate the first clock to satisfy the binding requirement.
For MPS2, we triple the clock, and add the clock-names property, as this
is required by the Linux primecell driver.
Try to make the clock-names more consistent on the way.

abe60a3a7a ARM: dts: Kill off skeleton{64}.dtsi
Remove the usage of skeleton.dtsi in the remaining dts files. It was
deprecated since commit 9c0da3cc61f1 ("ARM: dts: explicitly mark
skeleton.dtsi as deprecated"). This will make adding a unit-address to
memory nodes easier.

The main tricky part to removing skeleton.dtsi is we could end up with
no /memory node at all when a bootloader depends on one being present. I
hacked up dtc to check for this condition.

f3b2f758ec ARM: dts: realview: Fix some more duplicate regulator nodes
There's a bug in dtc in checking for duplicate node names when there's
another section (e.g. "/ { };"). In this case, skeleton.dtsi provides
another section. Upon removal of skeleton.dtsi, the dtb fails to build
due to a duplicate node 'fixedregulator@0'. As both nodes were pretty
much the same 3.3V fixed regulator, it hasn't really mattered. Fix this
by renaming the nodes to something unique. In the process, drop the
unit-address which shouldn't be present wtihout reg property.

The L2 cache comes up in a "safe mode" on the PB11MPCore, as
it has several issues. This sets it up properly with the right
size and associativity, also requiring the outer sync to be
disabled for the machine to boot properly.
