The ux500 platform will soon be converted to Device Tree only. When that
happens the old clock initialisation will be ripped out. In the meantime
however, we have to make a decision and call the appropriate
initialisation code manually.

If we supply a con_id then the clock framework will search for that name
in MUSB's Device Tree node for the 'clock-names' property. If it's absent
the clock request will fail. However, if we don't supply the con_id then
clk_get() will call into clk_sys() which will use the device name to
search for the appropriate clock, which is much more natural than forcing
'usb'.

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

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.

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).

The platform which it pertains to is no longer supported and is actually

These are required to request DBx500 PRCMU clocks from Device Tree. The
numbers used are taken directly from the Hardware Specification document.
We're moving them from the DBx500 PRCMU include file into the DT include
directory and referencing them from the former via a #include.

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.
