Subject: mmc: sdhci_am654: Set HIGH_SPEED_ENA for SDR12 and SDR25
From: Bhavya Kapoor <b-kapoor@xxxxxx>
commit 2265098fd6a6272fde3fd1be5761f2f5895bd99a upstream.
Timing Information in Datasheet assumes that HIGH_SPEED_ENA=1 should be
set for SDR12 and SDR25 modes. But sdhci_am654 driver clears
HIGH_SPEED_ENA register. Thus, Modify sdhci_am654 to not clear
HIGH_SPEED_ENA (HOST_CONTROL[2]) bit for SDR12 and SDR25 speed modes.
Fixes: e374e87538f4 ("mmc: sdhci_am654: Clear HISPD_ENA in some lower speed modes")
