[PATCH 0/5] Powerdomains: add OMAP2/3 powerdomain code and common OMAP type bitfield

[Paul Walmsley <paul@pwsan.com>]

Hi everyone,

This is the second version of the powerdomain patches.  It:

. replaces omap_type_t typedef with struct omap_chip_id

. fixes 34xx bug in OMAP type detection code

. removes all EXPORT_SYMBOLs - these can be added back in if powerdomain
  code needs to be used from loadable PM modules - the expectation is that
  it will only be used from PM code

. gets rid of all of the forward declarations in the powerdomain
  dependency definitions - now uses powerdomain names

. creates _pwrdm_lookup() to avoid potential race in pwrdm_register()

. gets rid of tabs in comments

. cleans up some dead structure members in struct powerdomain

. adds IVA2 sleepdep for DSS, PER, USBHOST

. is refreshed against current git head (e015fc7)

This version is tested against 3430SDP ES2.1, and compile-tested with
the N800 and 2430SDP configs.  Size, diffstat have been updated below.

Thanks to Tony & Jouni for review and comments.  More comments welcome,


- Paul

-------------------------

Hello,

this patch series adds a hardware control and monitoring interface for
OMAP2/3 powerdomains.  The interface is fully documented in the code.

The series also adds a common OMAP chip type detection bitfield for use
with powerdomain and clockdomain structures; it is planned to expand its
use to the clock framework in the future.

Powerdomain code tested on 3430SDP ES2.1; also boot-tested on N800.

Many people at Nokia and TI provided commentary and review during the
development of the powerdomain patches.  Particular help came from (in
alphabetical order): Jouni Högander, Tony Lindgren, Sakari Poussa,
Igor Stoppa, and Richard Woodruff.
