    arm64: dts: uniphier: add input-delay properties to Cadence eMMC node · ba6f7011
    Masahiro Yamada authored
    Since commit a89c472d ("mmc: sdhci-cadence: Update PHY delay
    configuration"), PHY parameters must be specified by DT.
    
    The hard-coded settings have been converted as follows:
    - SDHCI_CDNS_PHY_DLY_SD_DEFAULT -> cdns,phy-input-delay-legacy
    - SDHCI_CDNS_PHY_DLY_EMMC_SDR   -> cdns,phy-input-delay-mmc-highspeed
    - SDHCI_CDNS_PHY_DLY_EMMC_DDR   -> cdns,phy-input-delay-mmc-ddr
    
    The following have not been moved:
    - SDHCI_CDNS_PHY_DLY_SD_HS
       this is unneeded in the eMMC configuration
    - SDHCI_CDNS_PHY_DLY_EMMC_LEGACY
       this is never enabled by the driver as it is covered by
       SDHCI_CDNS_PHY_DLY_SD_DEFAULT
