1Broadcom IPROC SDHCI controller 2 3This file documents differences between the core properties described 4by mmc.txt and the properties that represent the IPROC SDHCI controller. 5 6Required properties: 7- compatible : Should be one of the following 8 "brcm,bcm2835-sdhci" 9 "brcm,sdhci-iproc-cygnus" 10 11- clocks : The clock feeding the SDHCI controller. 12 13Optional properties: 14 - sdhci,auto-cmd12: specifies that controller should use auto CMD12. 15 16Example: 17 18sdhci0: sdhci@0x18041000 { 19 compatible = "brcm,sdhci-iproc-cygnus"; 20 reg = <0x18041000 0x100>; 21 interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>; 22 clocks = <&lcpll0_clks BCM_CYGNUS_LCPLL0_SDIO_CLK>; 23 bus-width = <4>; 24 sdhci,auto-cmd12; 25 no-1-8-v; 26}; 27
