Jaedon Shin 5a3ab2815c mmc: DT: sdhci-brcmstb: Bindings document for common sdhci-brcmstb
Changes to the DT binding document to separate the BCM7425 and the
BCM7445.

A compatible string "brcm,bcm7425-sdhci" was representing the BCM7425
SDHCI host controller with all BRCMSTB SoCs including the BCM7445. Now
it should be separated because vary a bit in initialize each host
controller.

- Renames the DT binding document to common name.
- Adds a compatible string "brcm,bcm7445-sdhci" that is representing the
  BCM7445 with thereafter 28nm generation ARM based SoCs.

* BROADCOM BRCMSTB/BMIPS SDHCI Controller
This file documents differences between the core properties in mmc.txt
and the properties used by the sdhci-brcmstb driver.
NOTE: The driver disables all UHS speed modes by default and depends
on Device Tree properties to enable them for SoC/Board combinations
that support them.
Required properties:
- compatible: should be one of the following
- "brcm,bcm7425-sdhci"
- "brcm,bcm7445-sdhci"
Refer to clocks/clock-bindings.txt for generic clock consumer properties.
Example:
sdhci@f03e0100 {
compatible = "brcm,bcm7425-sdhci";
reg = <0xf03e0000 0x100>;
interrupts = <0x0 0x26 0x0>;
sdhci,auto-cmd12;
clocks = <&sw_sdio>;
sd-uhs-sdr50;
sd-uhs-ddr50;
};
sdhci@f03e0300 {
non-removable;
bus-width = <0x8>;
compatible = "brcm,bcm7425-sdhci";
reg = <0xf03e0200 0x100>;
interrupts = <0x0 0x27 0x0>;
sdhci,auto-cmd12;
clocks = <sw_sdio>;
mmc-hs200-1_8v;
};
