SD Host controller on Milbeaut consists of two controller parts. One is core controller F_SDH30, this is similar to sdhci-fujitsu controller. Another is bridge controller. This bridge controller is not compatible with sdhci-fujitsu controller. This is special for Milbeaut series. It has the several parts, - reset control - clock enable / select for SDR50/25/12 - hold control of DATA/CMD line - select characteristics for WP/CD/LED line - Re-tuning control for mode3 - Capability setting Timeout Clock / Base Clock / Timer Count for Re-Tuning / Debounce period These requires special procedures at reset or clock enable/change or further tuning of clock.
