      Host driver can't get a hint of DDR mode through ios->ddr flag anymore.
ios->timing is currently used to inform DDR mode as a substitute.
And capability of MMC_CAP_MMC_HIGHSPEED is added for DDR support.

      mmc: sdhci: use f_max instead of host->clock for timeouts · 65be3fef
      Andy Shevchenko authored 
      When timeout_clk is calculated the host->clock could be zero.
So, instead of host->clock the calculation now uses mmc->f_max.

      mmc: sdhci: check host->clock before using it as a denominator · 78a2ca27
      Andy Shevchenko authored 
      Sometimes host->clock could be zero which is a legal situation. This
patch checks host->clock before usage as a denominator when timeout is
calculated. A similar patch is applied for mmc core (see commit e9b86841,
"mmc: fix division by zero in MMC core").

Without this patch, the execution of the sdhci_calc_timeout could end up
with a backtrace:
