Subject: [PATCH v1 0/2] mmc: sdhci_f_sdh30: Add support for Milbeaut
Date: Tue, 26 Mar 2019 14:53:29 +0900 [thread overview]
Message-ID: <1553579609-6100-1-git-send-email-orito.takao@socionext.com> (raw)
The following patches add driver support for SD Host controller on
Socionext's Milbeaut M10V platforms.
SD Host controller on Milbeaut is consist 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.
