Subject: [PATCH v2 1/3] OMAP4: twl-common: Add twl6030 V1V8, V2V1 SMPS common configuration
Date: Wed, 9 May 2012 10:33:32 +0300 [thread overview]
Message-ID: <1336548814-1005-2-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1336548814-1005-1-git-send-email-peter.ujfalusi@ti.com>
V1V8 supply from twl6030 commonly used as VIO for the machine.
V2V1 is adviced to supply the twl6040, and also to feed the twl6030's
VCXIO_IN, and VDAC_IN inputs.
Create the common regulator configurations for these regulators:
Make the V2V1 as supply_regulator for VCXIO, VDAC.
Add twl6040 (1-004b) as consumer for V1V8, and V2V1.
