| 1 | Broadcom IPROC SDHCI controller | ||
| 2 | |||
| 3 | This file documents differences between the core properties described | ||
| 4 | by mmc.txt and the properties that represent the IPROC SDHCI controller. | ||
| 5 | |||
| 6 | Required properties: | ||
| 7 | - compatible : Should be "brcm,sdhci-iproc-cygnus". | ||
| 8 | - clocks : The clock feeding the SDHCI controller. | ||
| 9 | |||
| 10 | Optional properties: | ||
| 11 | - sdhci,auto-cmd12: specifies that controller should use auto CMD12. | ||
| 12 | |||
| 13 | Example: | ||
| 14 | |||
| 15 | sdhci0: sdhci@0x18041000 { | ||
| 16 | compatible = "brcm,sdhci-iproc-cygnus"; | ||
| 17 | reg = <0x18041000 0x100>; | ||
| 18 | interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>; | ||
| 19 | clocks = <&lcpll0_clks BCM_CYGNUS_LCPLL0_SDIO_CLK>; | ||
| 20 | bus-width = <4>; | ||
| 21 | sdhci,auto-cmd12; | ||
