Subject: [PATCH V3 1/4] mmc: sdhci-msm: Define new Register address map
Date:   Tue, 19 Jun 2018 11:09:18 +0530
Message-Id: <1529386761-4923-2-git-send-email-vviswana@codeaurora.org>
In-Reply-To: <1529386761-4923-1-git-send-email-vviswana@codeaurora.org>
References: <1529386761-4923-1-git-send-email-vviswana@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Sayali Lokhande <sayalil@codeaurora.org>

For SDCC version 5.0.0, MCI registers are removed from SDCC
interface and some registers are moved to HC.
Define a new data structure where we can statically define
the address offsets for the registers in different SDCC versions.
