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 one of the following

	       "brcm,bcm2835-sdhci"

	       "brcm,bcm2711-emmc2"

	       "brcm,sdhci-iproc-cygnus"

	       "brcm,sdhci-iproc"

Use brcm2835-sdhci for the eMMC controller on the BCM2835 (Raspberry Pi) and

bcm2711-emmc2 for the additional eMMC2 controller on BCM2711.

Use sdhci-iproc-cygnus for Broadcom SDHCI Controllers

restricted to 32bit host accesses to SDHCI registers.

Use sdhci-iproc for Broadcom SDHCI Controllers that allow standard

8, 16, 32-bit host access to SDHCI register.

- clocks : The clock feeding the SDHCI controller.

Optional properties:

  - sdhci,auto-cmd12: specifies that controller should use auto CMD12.

Example:

sdhci0: sdhci@18041000 {

	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;

};
