The SRAM that we are using here is phandle to MMIO-SRAM only. In the example
section you can see, sram node points to msmc_ram (ti,sram = <&msmc_ram>;) And
msmc_ram has compatible as "mmio-sram" in k3-am65-main.dtsi [1].

	msmc_ram: sram at 70000000 {
		compatible = "mmio-sram";
		reg = <0x0 0x70000000 0x0 0x200000>;

So I can use 'sram' property as there is no need to make this as ti specific.
Let me know if it seems good to you.
