From e89cec7ff86febe51eff001c0bf2c81ce601cfe4 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 21 Aug 2012 10:45:09 +0200 Subject: [PATCH] i2c: nomadik: stop fetching the regulator The regulator fetched by the Nomadik I2C driver is actually a voltage domain regulator. Stop doing this in the driver and let the power domain code handle any regulators, as discussed on the list.
