Broadcom IPROC SDHCI controller
|
|
|
|
This file documents differences between the core properties described
|
|
by mmc.txt and the properties that represent the IPROC SDHCI controller.
|
|
|
|
Required properties:
|
|
- compatible : Should be "brcm,sdhci-iproc-cygnus".
|
|
- clocks : The clock feeding the SDHCI controller.
|
|
|
|
Optional properties:
|
|
- sdhci,auto-cmd12: specifies that controller should use auto CMD12.
|
|
|
|
Example:
|
|
|
|
sdhci0: sdhci@0x18041000 {
|
|
compatible = "brcm,sdhci-iproc-cygnus";
|
|
reg = <0x18041000 0x100>;
|
|
interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&lcpll0_clks BCM_CYGNUS_LCPLL0_SDIO_CLK>;
|
|
bus-width = <4>;
|
|
sdhci,auto-cmd12;
|
|
no-1-8-v;
|
|
};
