mmc: sdhci: allow for eMMC 74 clock generation by controller
Snippet of code for how adaptation layer should handle the call:
/*
* eMMC spec calls for the host to send 74 clocks to the card
* during initialization, right after voltage stabilization.
* create the clocks manually right here.
*/
void generate_init_clocks_A0(struct sdhci_host *host, u8 power_mode)
{
struct sdhci_mmc_slot *slot = sdhci_priv(host);
if (slot->power_mode == MMC_POWER_UP &&
power_mode == MMC_POWER_ON) {
/* controller specific code here */
/* slot->power_mode holds previous power setting */
}
slot->power_mode = power_mode;
}
