      OMAP2/3 GPTIMER: allow system tick GPTIMER to be configurable at build · 0c00fb73
      Paul Walmsley authored 
      Add Kbuild code to allow the builder to select which GPTIMER block to use
for the Linux clockevents timer.  Practical choices at this point are
GPTIMER1 or GPTIMER12.  Both of these timers are in the WKUP powerdomain,
and so are unaffected by chip power management.  GPTIMER1 can use sys_clk
as a source, for applications where a high-resolution timer is more important
than power management.  GPTIMER12 has the special property that it has
the secure 32kHz oscillator as its source clock, which may be less prone
to glitches than the off-chip 32kHz oscillator.  But on HS devices, it may
not be available for Linux use.

At this point, it appears that most boards are fine with GPTIMER1, but
Beagle should use GPTIMER12.

      OMAP2/3 clockdomains: autodeps should respect platform flags · b5ea90ae
      Paul Walmsley authored 
      Fix the clockdomain autodep code to respect omap_chip platform flags.

Resolves "Unable to handle kernel paging request at virtual address
5f75706d" panic during power management initialization on OMAP2.

      OMAP2 clock: associate clocks with clockdomains at startup · 8a38aadc
      Paul Walmsley authored 
      The OMAP2 clock code was missing code to associate clocks with clockdomains
at registration time; fix this.

Resolves "Unhandled fault: alignment exception (0x001) at 0xc02c1b4e" (address
may vary) panic during clock framework init on OMAP2.  The alignment error
was caused by an attempt to dereference a pointer to a string (1-byte aligned)
as if it were a pointer to a structure.

Thanks to Felipe Balbi <felipe.balbi@nokia.com> for originally reporting this
bug.
