From e4b0b2cbbbaa085103229c03820755f20a64e581 Mon Sep 17 00:00:00 2001 From: Matt Porter Date: Thu, 23 Feb 2012 09:16:04 -0500 Subject: [PATCH] ARM: OMAP2+: gpmc-smsc911x: add required smsc911x regulators This fixes smsc911x support on platforms using gpmc_smsc911x_init(). Commit c7e963f6888816 (net/smsc911x: Add regulator support) added the requirement that platforms provide vdd33a and vddvario supplies.
