MTD developers,
Please ignore this patch.

I accidentally sent this patch to a wrong ML.
Sorry for the noise.

> Since commit a04e2b383401 ("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
