mmc: sdhci-of-esdhc: add SDR50 mode support for SD/MMC Legacy Adapter Card
The eSDHC is not compatible with SD spec well, so we need
to use eSDHC-specific code to switch to SDR50 mode.
1. IO signal voltage switching, eSDHC uses SDHC_VS to switch
io voltage and it's needed to configure a global utilities
register SCFG_SDHCIOVSELCR(if it has) and SDHC_VS signal.
2. Before executing tuning procedure, eSDHC should set its own
tuning block.
static const struct sdhci_ops sdhci_esdhc_ops = {
...
.set_tuning_block = esdhc_set_tuning_block,
.signal_voltage_switch = esdhc_signal_voltage_switch,
};
