    mmc: sdhci_am654: Add Initial Support for AM654 SDHCI driver · 41fd4cae
    Faiz Abbas authored
    The host controllers on TI's AM654 SOCs are not compatible with
    the phy and consumer model of the sdhci-of-arasan driver. It turns out
    that for optimal operation at higher speeds, a special tuning procedure
    needs to be implemented which involves configuration of platform
    specific phy registers.
    Therefore, branch out to a new sdhci_am654 driver and add the phy
    register space with all phy configurations to it. Populate AM654
    specific callbacks to sdhci_ops and add SDHCI_QUIRKS wherever
    Only add support for upto High Speed for SD card and upto DDR52 speed
    mode for eMMC. Higher speeds will be added in subsequent patches.
