571 * omap_hsmmc_reset() - Full reset of each HS-MMC controller
572 *
573 * Ensure that each MMC controller is fully reset. Controllers
574 * left in an unknown state (by bootloader) may prevent retention
575 * or OFF-mode. This is especially important in cases where the
576 * MMC driver is not enabled, _or_ built as a module.
577 *
578 * In order for reset to work, interface, functional and debounce
579 * clocks must be enabled. The debounce clock comes from func_32k_clk
580 * and is not under SW control, so we only enable i- and f-clocks.
