Subject: [PATCH 4/6] ARM: OMAP2+: Remove omap4 pdata from hsmmc.c
Date: Fri, 17 May 2013 12:17:59 -0700	[thread overview]
Message-ID: <20130517191759.468.9983.stgit@localhost> (raw)
In-Reply-To: <20130517191304.468.73487.stgit@localhost>

This is no longer needed as omap4 is now booted using
device tree.
