[PATCH v2 0/2] mmc: sdhci-milbeaut: add Milbeaut SD driver

[Takao Orito]

The following patches add driver for SD Host controller on
Socionext's Milbeaut M10V platforms.

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.
