Subject: [PATCH 3/3 v2] dts: Add ESDHC weird voltage bits workaround
Date: Tue, 3 Aug 2010 11:11:12 +0800 [thread overview]
Message-ID: <1280805072-26112-3-git-send-email-tie-fei.zang@freescale.com> (raw)
In-Reply-To: <1280805072-26112-2-git-send-email-tie-fei.zang@freescale.com>
P4080 ESDHC controller does not support 1.8V and 3.0V voltage. but the
host controller capabilities register wrongly set the bits.
This patch adds the workaround to correct the weird voltage setting bits.
Only 3.3V voltage is supported for P4080 ESDHC controller.
