[PATCHv2 00/12] ARM: OMAP: core/hwmod: first set of fixes for 3.5-rc

Here is an initial set of fixes for power management and OMAP core
infrastructure for 3.5-rc.  Most of these patches address boot
warnings and power management problems on OMAP4, although a few of
them address more general issues.

Thanks to (in alphabetical order) Benoît Cousson, Tero Kristo, Kevin
Hilman, Vaibhav Hiremath, and Tony Lindgren for help with this series.

Compile-test information is below.  The patches been boot-tested on
OMAP3530 ES3.0 BeagleBoard and OMAP4430 ES2.0 PandaBoard.  Suspend and
idle are broken on both of these platforms right now.  Unfortunately
my board farm is down at the moment, so I'm unable to do further
testing on other boards.  Boot logs, such as they are, are available


These patches are available via git from git://git.pwsan.com/linux-2.6
in the branch 'omap_fixes_a_3.5rc'.

This second version contains several changes:

- Rebased on v3.5-rc2.

- A new patch has been added to change the 32k sync timer
  SIDLEMODE flags ("ARM: OMAP4: hwmod data: fix 32k sync timer
  idle modes").

- A bug has been fixed ("ARM: OMAP2+: hwmod code/data: fix 32K
  sync timer").

- setup_preprogram code for the AESS and FSUSB IP blocks has been
  moved to include/linux/platform_data at Tony's request
  ("ARM: OMAP4+: AESS: enable internal auto-gating during initial
   setup" and "ARM: OMAP2+: usb_host_fs: add custom
   setup_preprogram for usb_host_fs (fsusb)")
