Subject: [PATCH 2/3] ARM: OMAP3: HWMOD: add SYSC_HAS_ENAWAKEUP for dispc
Date: Mon, 23 Jan 2012 12:15:29 +0000 [thread overview]
Message-ID: <1327320930-14550-3-git-send-email-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <1327320930-14550-1-git-send-email-tomi.valkeinen@ti.com>
dispc's sysc_flags is missing SYSC_HAS_ENAWAKEUP flag. This seems to
cause SYNC_LOST errors from the DSS when the power management is
enabled.
This patch adds the missing SYSC_HAS_ENAWAKEUP flag. Note that there are
other flags missing also (clock activity, DSI's sysc flags), but as they
are not critical, they will be fixed in the next merge window.
