Subject: [PATCH 02/10] OMAP4: TWL: Add common omapdss supplies
Date: Tue, 20 Sep 2011 11:18:18 +0300	[thread overview]
Message-ID: <1316506706-18941-3-git-send-email-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <1316506706-18941-1-git-send-email-tomi.valkeinen@ti.com>

OMAP DSS normally gets power from VCXIO on OMAP4. Add configuration for
this into twl-common.c

Mark VCXIO as always_on, as VCXIO is used by multiple components,
including the MPU, and turning it off when DSS doesn't need it would
lead the device to halt.
