[PATCH 5/8] mmc: sdhci-msm: configure CORE_CSR_CDC_DELAY_CFG to recommended value
From: Ritesh Harjani
Date: Wed Dec 28 2016 - 06:07:38 EST
From: Subhash Jadavani <subhashj@xxxxxxxxxxxxxx>
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.
