Take in account the used variant with amlogic,meson-gx-mmc.

This does not look correct. Either gx is alone (not compatible with
gxbb) or it is compatible with gxbb. Cannot be both.

This ishow it's used in DT:

arch/arm64/boot/dts/amlogic/meson-gx.dtsi:                              compatible = "amlogic,meson-gx-mmc", "amlogic,meson-gxbb-mmc";
arch/arm64/boot/dts/amlogic/meson-axg.dtsi:                             compatible = "amlogic,meson-axg-mmc";
arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi:                      compatible = "amlogic,meson-axg-mmc";

So I'll drop the amlogic,meson-gx-mmc in the first enum to have :
+properties:
+  compatible:
+    oneOf:
+      - const: amlogic,meson-axg-mmc
+      - items:
+          - const: amlogic,meson-gx-mmc
+          - const: amlogic,meson-gxbb-mmc

It's right ?

-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>;
-	};
