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	       "brcm,sdhci-iproc"
11
12Use brcm2835-sdhci for Rasperry PI.
13
14Use sdhci-iproc-cygnus for Broadcom SDHCI Controllers
15restricted to 32bit host accesses to SDHCI registers.
16
17Use sdhci-iproc for Broadcom SDHCI Controllers that allow standard
188, 16, 32-bit host access to SDHCI register.
19
20- clocks : The clock feeding the SDHCI controller.
21
22Optional properties:
23  - sdhci,auto-cmd12: specifies that controller should use auto CMD12.
24
25Example:
26
27sdhci0: sdhci@18041000 {
28	compatible = "brcm,sdhci-iproc-cygnus";
29	reg = <0x18041000 0x100>;
30	interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
31	clocks = <&lcpll0_clks BCM_CYGNUS_LCPLL0_SDIO_CLK>;
32	bus-width = <4>;
33	sdhci,auto-cmd12;
34	no-1-8-v;
35};
