Subject: [PATCH 4/4] OMAP3: PM: PM_MPUGRPSEL writes should use GRPSEL macros, not EN macros
Date: Tue, 20 Apr 2010 01:45:53 -0600	[thread overview]
Message-ID: <20100420074550.3015.65546.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100420074204.3015.56304.stgit@localhost.localdomain>

Writes to the PM_*GRPSEL registers should use _GRPSEL_ macros, not _EN_ macros,
to match the TRM and guard against inadvertent error.  This patch should
not cause any functional change.
