Broadcom IPROC SDHCI controllerThis file documents differences between the core properties describedby 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;};
