Subject: [PATCH 0/4] OMAP3: fix powerdomain hardware save-and-restore support
Date: Wed, 25 Jun 2008 18:09:34 -0600 [thread overview]
Message-ID: <20080626000415.18779.25924.stgit@localhost.localdomain> (raw)
This series revises the support for automatic hardware-controlled
powerdomain context save-and-restore (SAR). Previously, this was
partially handled through the clock framework; but handling it via the
powerdomain framework is a better solution.
The patches:
- add functions to the powerdomain code to enable and disable
automatic SAR,
- move the USBHOST SAR support from the clock fw to the powerdomain
layer,
- add support for USBTLL SAR,
- enable SAR for all powerdomains that support it upon powerdomain
initialization.
Boot-tested on 3430SDP ES2.
