-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@...41000 {
-	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;
-};
