* 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"
- "brcm,bcm7216-sdhci"
Refer to clocks/clock-bindings.txt for generic clock consumer properties.
Example:
sdhci@84b0000 {
sd-uhs-sdr50;
sd-uhs-ddr50;
sd-uhs-sdr104;
sdhci,auto-cmd12;
compatible = "brcm,bcm7216-sdhci",
"brcm,bcm7445-sdhci",
"brcm,sdhci-brcmstb";
reg = <0x84b0000 0x260 0x84b0300 0x200>;
reg-names = "host", "cfg";
interrupts = <0x0 0x26 0x4>;
interrupt-names = "sdio0_0";
clocks = <&scmi_clk 245>;
clock-names = "sw_sdio";
};
sdhci@84b1000 {
mmc-ddr-1_8v;
mmc-hs200-1_8v;
mmc-hs400-1_8v;
mmc-hs400-enhanced-strobe;
supports-cqe;
non-removable;
bus-width = <0x8>;
compatible = "brcm,bcm7216-sdhci",
"brcm,bcm7445-sdhci",
"brcm,sdhci-brcmstb";
reg = <0x84b1000 0x260 0x84b1300 0x200>;
reg-names = "host", "cfg";
interrupts = <0x0 0x27 0x4>;
interrupt-names = "sdio1_0";
clocks = <&scmi_clk 245>;
clock-names = "sw_sdio";
};
