[PATCH 0/8] ARM: OMAP: HDQ/1-wire: update driver to use runtime PM

[ This series intended for the 3.4 merge window ]

Update the OMAP HDQ/1-wire driver to use runtime PM.  This includes
integration with the rest of the OMAP power management and device
enumeration code.  And there was a bug/undocumented feature in the HDQ reset
process that needed a workaround.

Evgeniy, could you ack the change to the 1-wire driver?  Otherwise, if you
would like to merge it, we'd probably need to split this series across two
merge windows.

The series has been boot-tested on an OMAP35xx Beagleboard, but more
testing would certainly be welcome.  Before merging it, I intend to
boot-test it on OMAP2 and OMAP4 boards at least, but I don't think I
have any boards with a 1-wire chip on-board.  So if someone has an OMAP
board with 1-wire devices, (hint hint Neil ;-) a quick test would be
much appreciated.
