of: Add .of suffix to device names from devicetree ...

Previous implementation used to add a number to the device names
for devices registered from the device tree which did not have a 'reg'
property, thus a device node named "state" resulted in a device name
"state.<x>". Current implementation skips that number and we get a
device named "state". This conflicts with our barebox state
implementation which tries to register a device named "state" itself.
We could rename the state device nodes of all our device trees, but it
causes less trouble to rename the devices.

This adds a ".of" suffix to the device names for devices registered from
the device tree which also has the nice effect that they now can easily
be recognized.

Fixes: 7e497d48acbd11 ("of: Port latest of_device_make_bus_id() implementation")

clk: fix NULL deref without OF node in debug message ...

of_clk_add_provider() may be called for devices added via
add_generic_device(). There is no OF node in this case, leading to a crash
when debug logs are enabled.

This affects various i.MX CPUs, which add imx*-ccm clock devices using
add_generic_device().

Upstream dts files changed to the generic binding for mii phys, so we
have to support it in barebox aswell. The barebox internal device trees
haven't been changed, so support them until all have changed. We print
a warning to add some motivation to change.

nand: denali: remove undefined GFP_DMA flag ...

This was a remnant from porting kernel code to barebox.
While being uncritical so far, this will now cause a compiler error
since kzalloc is not a define but a static inline function.

As the kzalloc() 'mode' argument was ignored before and still will be,
it is safe to remove the parameter.

ARM: i.MX: When SRSR shows wdog then lookup reset source in wdog ...

On i.MX6 when the watchdog has resetted the system then the SRSR
register correctly shows that the watchdog has resetted the system.
This is not the desired result though, a "reset" in barebox or "reboot"
in Linux should result in "RST" as reset source. So instead of making
the SRSR register value overwrite the reset source read from the
watchdog registers, interpret the SRSR value corresponding to watchdog
reset as "lookup details in the watchdog registers".

ARM: clk: rk3188: don't set same clk rate twice ...

We found setting a clock rate which has already been set, rk3188 (radxa rock
pro) bails out. This is a quick fix only. Underlying situation not (yet)
investigated: why it is even trying to set it to the same rate again. It
remains to state that some but not all rrpro boards exhibit this behaviour, no
other rk3188 boards have been tested.

net: designware: look for a child device node for MDIO bus ...

The Designware driver registers a local MDIO bus for each MAC device,
but without setting a device node pointer for the MDIO bus device.  In
this case, mdiobus_register() will use the MDIO bus's parent device node
(if any) as the MDIO device node.

If the MAC device node has a child node compatible with
"snps,dwmac-mdio", let us use that as the MDIO bus device node.
Otherwise, leave the MDIO bus device node pointer set to NULL and carry
on as before.

The upshot is that PHY device nodes can now be placed in an intermediate
node for the MDIO bus instead of having to place them directly in the
Designware MAC device node.

(Tested on a Terasic DE0-Nano-SoC with a suitably modified device tree.)
