Subject: [PATCH 0/3] OMAP2+: powerdomain: add fn to determine whether pwrdm is always on
Date: Mon, 07 Mar 2011 19:15:46 -0700 [thread overview]
Message-ID: <20110308021018.31946.29962.stgit@twilight.localdomain> (raw)
Hello,
this series adds an OMAP powerdomain API function that allows its
callers to determine whether a particular powerdomain can ever lose
register or memory bank context while the SoC is powered. This is
intended for use by driver-subarch integration code (i.e.,
arch/arm/*omap*) to pass a flag to the driver to determine whether it
is necessary to save and restore driver context.
As part of this series, fix some long-standing bugs in the powerdomain
data. These fixes are necessary for this function to work, and also
for OSWR support.
Tested on OMAP35xx BeagleBoard and OMAP44xx Pandaboard.
