Amlogic SD / eMMC controller for S905/GXBB family SoCs
|
|
|
|
The MMC 5.1 compliant host controller on Amlogic provides the
|
|
interface for SD, eMMC and SDIO devices.
|
|
|
|
This file documents the properties in addition to those available in
|
|
the MMC core bindings, documented by mmc.txt.
|
|
|
|
Required properties:
|
|
- compatible : contains one of:
|
|
- "amlogic,meson-gx-mmc"
|
|
- "amlogic,meson-gxbb-mmc"
|
|
- "amlogic,meson-gxl-mmc"
|
|
- "amlogic,meson-gxm-mmc"
|
|
- clocks : A list of phandle + clock-specifier pairs for the clocks listed in clock-names.
|
|
- clock-names: Should contain the following:
|
|
"core" - Main peripheral bus clock
|
|
"clkin0" - Parent clock of internal mux
|
|
"clkin1" - Other parent clock of internal mux
|
|
The driver has an internal mux clock which switches between clkin0 and clkin1 depending on the
|
|
clock rate requested by the MMC core.
|
|
|
|
Example:
|
|
|
|
sd_emmc_a: mmc@70000 {
|
|
compatible = "amlogic,meson-gxbb-mmc";
|
|
reg = <0x0 0x70000 0x0 0x2000>;
|
|
interrupts = < GIC_SPI 216 IRQ_TYPE_EDGE_RISING>;
|
|
clocks = <&clkc CLKID_SD_EMMC_A>, <&xtal>, <&clkc CLKID_FCLK_DIV2>;
|
|
clock-names = "core", "clkin0", "clkin1";
|
|
pinctrl-0 = <&emmc_pins>;
|
|
};
