Subject: Re: [PATCH v3 0/2] mmc: sdhci-milbeaut: add Milbeaut SD driver


Hello

Does anyone have any comments on this ?

> 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.
