-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"
- - "amlogic,meson-axg-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.
-- resets : phandle of the internal reset line
-
-Optional properties:
-- amlogic,dram-access-quirk: set when controller's internal DMA engine cannot access the
- DRAM memory, like on the G12A dedicated SDIO controller.
-
-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>;
- resets = <&reset RESET_SD_EMMC_A>;
- };
