Hi, I have recently observed that the quirk SDHCI_QUIRK2_NEED_DELAY_AFTER_INT_CLK_RST I have introduced doesn't fix all the bugs relative to the internal clock disabling while configuring the SD clock. This delay was introduced because of a re-synchronisation done when disabling the internal clock. Unfortunately, we can still have clock stabilization bug even if it occurs rarely. Moreover, trying to use presets, disabling the internal clock causes an unexpected switch to the base clock. It should be solved on next revision of the chip. For those reasons plus the non acceptance of new quirks, I have decided to remove it and to implement my own set_clock() function. In ordrer to reduce code duplication with the sdhci set_clock function, I moved some of the code in a new sdhci_compute_clock_config() function.
