Subject: [PATCH 1/5] mmc: core: don't try to switch block size for dual rate mode
Date: Wed, 21 Sep 2016 09:43:49 +0800 [thread overview]
Message-ID: <1474422233-29355-2-git-send-email-shawn.lin@rock-chips.com> (raw)
In-Reply-To: <1474422233-29355-1-git-send-email-shawn.lin@rock-chips.com>
From: Ziyuan Xu <xzy.xu@rock-chips.com>
Per spec, block size should always be 512 bytes for dual rate mode,
so any attempts to switch the block size under dual rate mode should
be neglected.
