Improve the binding example by removing all the leading 0x to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
Converted using the following command:
find Documentation/devicetree/bindings -name "*.txt" -exec sed -i -e 's/([^ ])\@0x([0-9a-f])/$1\@$2/g' {} +

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,sdhci-iproc-cygnus"
|
|
"brcm,sdhci-iproc"
|
|
|
|
Use brcm2835-sdhci for Rasperry PI.
|
|
|
|
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;
|
|
};
