On DH STM32MP1 SoM in PDK2 carrier board,
Tested-by: Marek Vasut <marex@denx.de>

btw. it seems this sets BTRx DATLAT and CLKDIV to 0xf , it's "Don't
care" in the datasheet for Muxed mode, but then it should probably be
set to 0.

The bindings I used are below:

&fmc {
        pinctrl-names = "default", "sleep";
        pinctrl-0 = <&fmc_pins_b>;
        pinctrl-1 = <&fmc_sleep_pins_b>;
        status = "okay";
        #address-cells = <1>;
        #size-cells = <1>;
        /delete-property/interrupts;
        /delete-property/dmas;
        /delete-property/dma-names;
        reg = <0x58002000 0x1000>;
        ranges;

        ebi {
                #address-cells = <2>;
                #size-cells = <1>;
                compatible = "st,stm32mp1-fmc2-ebi";
