Subject: [PATCH v8 00/22] OMAP USB Host cleanup

Hi,

This patchset addresses the following

- Consolidate USB Host platform data.
- Avoid addressing clocks one by one by name and use a for loop + bunch
  of cleanups.
- Get number of channels/ports dynamically either from revision register
  or from platform data. Avoids getting clocks that are not present.
- Add OMAP5 and HSIC mode (Not tested).

v8:
- Re-arranged patch "USB-ehci-omap-Don-t-free-gpios-that-we-didn-t-reques.patch"
  to be the first since it is a candidate for stable.
- Fixed issues raised by Felipe, i.e. indentation and use of switch ()

v7:
- Updated patch 4 to not hold a spinlock when using clk_get().
- Updated patches 3 and 11 to return -EADDRNOTAVAIL on failure of
  demv_request_and_ioremap().

v6:
- Added USB Host platform data consolidation patch as the first patch.
  based on request from Tony.
- Rebased on v3.8-rc3.

v5:
- Rebased on top of todays arm-soc/for-next.
- Removed the clock merging patch from the list.
- Updated patches 14, 19 and 20 to accomodate the above change.
- Added patch 22 to fix a build warning.

v4:
- Added appropriate maintainers in to/cc.
- minor print message fix in patch 23 to maintain consistency.

v3:
- Rebased on arm-soc/for-next commit f979306c4d38d213c6977aaf3b1115e8ded71e3a.
- Rearranged patch that get rids of cpu_is_omap..() macros.
- Coding style fixes.

v2:
- Clocks are allocated dynamically based on number of ports available
  on the platform.
- Reduced console spam if non critical clocks are not found on the platform.
- Get rid of cpu_is_.. macros from USB host driver.

cheers,
-roger
