Subject: [RFC PATCH 05/15] sd: emmc: support idle state in CMD2
Date: Thu, 11 Feb 2021 13:47:16 +0530 [thread overview]
Message-ID: <1613031446-22154-6-git-send-email-sai.pavan.boddu@xilinx.com> (raw)
In-Reply-To: <1613031446-22154-1-git-send-email-sai.pavan.boddu@xilinx.com>
eMMC is expected to be in idle-state post CMD1. Ready state is an
intermediate stage which we don't come across in Device identification
mode.
