Subject: [RESEND PATCHv1 5/8] mmc: sdhci-msm: configure CORE_CSR_CDC_DELAY_CFG to recommended value
Date: Tue, 10 Jan 2017 12:30:49 +0530 [thread overview]
Message-ID: <1484031652-12059-6-git-send-email-riteshh@codeaurora.org> (raw)
In-Reply-To: <1484031652-12059-1-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.
