13description:
14  The SOCIONEXT Milbeaut SDHCI controller is a specialized SD Host
15  Controller found in some of Socionext's Milbeaut image processing SoCs.
16  It features a dedicated "bridge controller." This bridge controller
17  implements special functions like reset control, clock management for
18  various SDR modes (SDR12, SDR25, SDR50) and physical pin property settings.
