Subject: [RFC PATCH 10/15] sd: emmc: Update CID structure for eMMC
Date: Thu, 11 Feb 2021 13:47:21 +0530	[thread overview]
Message-ID: <1613031446-22154-11-git-send-email-sai.pavan.boddu@xilinx.com> (raw)
In-Reply-To: <1613031446-22154-1-git-send-email-sai.pavan.boddu@xilinx.com>

CID structure is little different for eMMC, w.r.t to product name and
manufacturing date.
