Merge "pxa changes for v4.2 cycle" from Robert Jarzmik:

The main and only feature is the conversion of all pxa variants to clock
framework. This encompasses pxa25x, pxa27x and pxa3xx, for all boards.

This should be a disruptive cycle in the normally quiet pxa history, as
the change can break any platform, and the test were performed on only 4
boards (lubbock, zylonite, mioa701, cm-x300).

Since the WDT is what's used to drive restart and power off, it makes
more sense to keep it there, where the regs are already mapped and
definitions for them provided.  Note that this means you may need to
add CONFIG_BCM2835_WDT to retain functionality of your kernel.

The only thing we were using this 16MB mapping of IO peripherals for

the kernel will call debug_ll_io_init() for us, which maps the single

Transition the PXA25x, PXA27x and PXA3xx CPUs to the clock framework.
This transition still enables legacy platforms to run without device

Transition the PXA25x and PXA27x CPUs to the clock framework.
This transition still enables legacy platforms to run without device
tree as before, ie relying on platform data encoded in board specific

The transition breaks the previous clocks activation of pin
control (gpio11 and gpio12). Machine files should be amended to take
that into account.

This is the last step of clock framework transition for pxa25x and
pxa27x, leaving only pxa3xx for further work.

Since pxa clocks were ported to the clock framework, an ordering issue
appears between clocks and clocksource initialization. As a consequence,
the pxa timer clock cannot be acquired in pxa_timer, and is disabled by
clock framework because it is "unused".

The ordering issue is that in the kernel boot sequence :
  start_kernel()
    ...
    time_init()
      -> pxa_timer()
        -> here the clocksource is initialized
    ...
    rest_init()
      kernel_init()
	initcalls
	  -> here the clocks are initialized

In the current sequence, the clocks are initialized way after pxa_timer,
which cannot acquire the OSTIMER0 clock.

To solve this issue, the clocks initialization is moved to pxa_timer(),
so that clocks are initialized before clocksource for non device-tree.
For device-tree, the standard arm time_init() will take care of the
ordering.
