Kernel-4.18.0-80.el8_brcm,sdhci-brcmstb

  • BROADCOM BRCMSTB/BMIPS SDHCI Controller

This file documents differences between the core properties in mmc.txt
and the properties used by the sdhci-brcmstb driver.

NOTE: The driver disables all UHS speed modes by default and depends
on Device Tree properties to enable them for SoC/Board combinations
that support them.

Required properties:

  • compatible: should be one of the following
    • “brcm,bcm7425-sdhci”
    • “brcm,bcm7445-sdhci”

Refer to clocks/clock-bindings.txt for generic clock consumer properties.

Example:

sdhci@f03e0100 {
    compatible = "brcm,bcm7425-sdhci";
    reg = <0xf03e0000 0x100>;
    interrupts = <0x0 0x26 0x0>;
    sdhci,auto-cmd12;
    clocks = <&sw_sdio>;
    sd-uhs-sdr50;
    sd-uhs-ddr50;
};

sdhci@f03e0300 {
    non-removable;
    bus-width = <0x8>;
    compatible = "brcm,bcm7425-sdhci";
    reg = <0xf03e0200 0x100>;
    interrupts = <0x0 0x27 0x0>;
    sdhci,auto-cmd12;
    clocks = <sw_sdio>;
    mmc-hs200-1_8v;
};
