Subject: [PATCH 7/7] ARM: OMAP2+: PM: reorganize the powerdomain API in public and private parts
Date: Wed, 12 Sep 2012 11:55:32 +0200	[thread overview]
Message-ID: <1347443732-7411-8-git-send-email-j-pihet@ti.com> (raw)
In-Reply-To: <1347443732-7411-1-git-send-email-j-pihet@ti.com>

The newly added code for functional power states re-defines the
API to query and control the power domains settings.

The API is now split in the following parts in powerdomain.h:
- the public or external API, to be used by external PM components:
  cpuidle, suspend, pmxxxx, clock* etc.
- the private or internal API, to be used by the low level PM code
  only: powerdomain*, pm-debug, hwmod, voltage, clockdomainxxxx.

The function omap_set_pwrdm_state is not used anymore and so is
removed.

No functional change is introduced by this patch.

Note: the API reorganization in a public and private header files
is not part of this patch, this comes as a subsequent clean-up
patch series.
