[PATCHv4 0/6] ARM: OMAP3+: IO daisychain support fixes

[Tero Kristo]

Hi,

Changes compared to previous version:

- patch2:
 * changed timeout value to 100us (from 1000)
 * added poll for the IO status == 0 at the end of trigger sequence
- patch4:
 * omap3: global wakeup done in PRM init instead of OMAP3 PM init
 * omap4: moved global wakeup enable from trigger func to PRM init

Tested on omap3beagle / omap4blaze, suspend / resume works with io chain.
