Subject: [PATCH 5/8] mmc: sdhci-msm: configure CORE_CSR_CDC_DELAY_CFG to recommended value
Date: Wed, 28 Dec 2016 16:36:28 +0530	[thread overview]
Message-ID: <1482923191-17362-6-git-send-email-riteshh@codeaurora.org> (raw)
In-Reply-To: <1482923191-17362-1-git-send-email-riteshh@codeaurora.org>

From: Subhash Jadavani <subhashj@codeaurora.org>

Program CORE_CSR_CDC_DELAY_CFG for hardware recommended 1.25ns delay.
We may see data CRC errors if it's programmed for any other delay
value.
