Shawn Lin 8cc3528922 mmc: sdhci: clarify the get_timeout_clock callback ... Currently the get_timeout_clock callback doesn't clearly have a statement that it needs the variant drivers to return the timeout clock rate in kHz if the SDHCI_TIMEOUT_CLK_UNIT isn't present, otherwise the variant drivers should return it in MHz. It's also very likely that further variant drivers which are going to use this callback will be confused by this situation. Given the fact that moderm sdhci variant hosts are very prone to get the timeout clock from common clock framework (actually the only three users did that), it's more natural to return the value in Hz and we make an explicit comment there. Then we put the unit conversion inside the sdhci core. Thus will improve the code and prevent further misuses.
