From fa3f99384c20751c66962848807403ff171dc02f Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Mon, 31 Aug 2009 21:52:53 +0800 Subject: pxamci: introduce mmc_has_26mhz() and include pxa935 Along with more processor supporting 26MHz mode (including pxa935), introduce an individual macro mmc_has_26mhz() for this.
