Subject: [PATCHv7 01/12] ARM: OMAP4: PM: add errata support
Date: Thu, 19 Jul 2012 16:26:21 +0300	[thread overview]
Message-ID: <1342704392-23657-2-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1342704392-23657-1-git-send-email-t-kristo@ti.com>

Added similar PM errata flag support as omap3 has. This should be used
in similar manner, set the flags during init time, and check the flag
values during runtime.
