[PATCH v1 0/5] Fixes for the pxa common clocks

[PATCH v1 0/5] Fixes for the pxa common clocks

[Robert Jarzmik]

Hi Mike, Arnd, Haojian,

Here are all the fixes I had gathered so far on pxa clocks serie.

Amongst these :
 - only patch 1/5 is a really required fix
 - patches 2/5 and 3/5, after review, could go to the next merge window
 - patch 4/5 should be carefully reviewed by pxa and arm people, but not merged
   until pxa25x support is in place.
 - patch 5/5 should only be considered if ever Tomeu's changes get in.

I'm sending these to give us time to review ahead of time. And of course they
have only been tested on a single pxa27x platform, but once my environment is
ready, I'll pass a full build test on all PXA platform.

Cheers.

[PATCH v1 1/5] clk: pxa: fix pxa27x CCCR bit usage

[Robert Jarzmik]

Trivial fix to check the A bit of CCCR for memory frequency
calculations, where the shift of the bit index was missing, triggering a
wrong calculation of memory frequency.

[PATCH v1 2/5] clk: pxa: declare init function and data __init

[Robert Jarzmik]

As the clock descriptions are constant and only usefull at init time,
mark them as such by :
 - spliting clock description (desc) and clock private data (dynamic)
 - mark __initdata clock descriptions

This makes all the register and descriptions of the clocks to go after
kernel init phase.

[PATCH v1 3/5] clk: pxa: keep clocks initialization separated per variant

[Robert Jarzmik]

Have each pxa variant (pxa25x, pxa27x, pxa3xx) have its own device-tree
clock initializing function, to be able to register its own specific
core clocks.

Apply that change specifically to pxa27x.

[PATCH v1 4/5] DON'T MERGE ME: arm: pxa: change clocks init sequence

[Robert Jarzmik]

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.

[PATCH v1 5/5] DON'T MERGE ME: clk: pxa: migrate to the clk_core API

[Robert Jarzmik]

After the clock framework split structure clk and clk_core, amend the
pxa clock providers for the new API.

This patch was tested on a pxa270 on top of Tomeu's patches v9.
