Lee Jones b4bdc81b5b clk: ux500: Add a 2-cell Device Tree parser for obtaining PRCC clocks
PRCC (peripheral and kernel) clocks are specified using a property tuple
<&phandle base bit>, where 'base' is the peripheral (1, 2, 3, 5 or 6),
and bit is read-in value into that peripheral stipulated by the hardware
specification.

Lee Jones 82b0f4b7c5 clk: ux500: Copy u8500_clk_init() ready for DT enablement
Here we're using the old clock initialisation function as a template.
It's necessary to remove all of the clk_register_clkdev() calls as
they don't make sense when booting with Device Tree.

Lee Jones 0473b177c3 clk: ux500: Remove BML8580 clock
There is no mention of the PRCMU_BML8580CLK in any of the Design
Specifications for the chips supported in Mainline. In fact, where it
is incorrectly used in the u8540 clock definition driver it would
have the side effect of using the incorrect clock management address
([PRCM_BML8580CLK_MGT] 0x108 instead of the correct value 0x04C).

Lee Jones 970eb8fe13 ARM: ux500: Don't attempt to enable the Nomadik System Timer twice
When booting with DT enabled we already call clocksource_of_init(),
which in turn calls the OF version of nmdk_timer_init().

Lee Jones 8132ed1bb8 ARM: ux500: Add a DT node for the Nomadik System Timer (MTU0)
The MTU0 is required for full booting of the system. The driver has
been previously DT:ed and is in use on the Nomadik platform, but we
also need to enable it on ux500 based systems.

We're moving them from the DBx500 PRCMU include file into the DT include

Sebastian Andrzej Siewior 4a6cd43fb7 dt: dbx5x0: remove mentor,musb binding
The "mentor,musb" binding isn't documented so I was about
to document it.

The node is missing a few properties for configuration like
"multipoint", "dyn_fifo", "num_eps" or "ram_bits". However
I am not sure "missing" is the right word here because some
of those informations might be obtained from the chip itself
but it is not done (yet).

Further the ePARP 2.3.1 says the matching goes from left to
right taking the fist match. Right now there is jus a driver
for "stericsson,db8500-musb" and none for "mentor,musb".
I'm not 100% that it is simply possible to have a generic
since even for DMA we have ifdefs in the driver between
"generic mentor dma" and "ux500 dma" and I mean within musb
and not the dma code.

For that reason (that I am not sure a generic musb binding
is possible and how its binding / required properties will
look like) and the reason that we have here a minor binding
without a driver to look at I suggest to remove that binding.

If the majority of people prefer to keep this binding I'm
curious how the documentation of the binding should look like.
