+Hisilicon Hi6220 SRAM controller
+
+Required properties:
+- compatible : "hisilicon,hi6220-sramctrl", "syscon"
+- reg : Register address and size
+
+Hisilicon's SoCs use sram for multiple purpose; on Hi6220 there have several
+SRAM banks for power management, modem, security, etc. Further, use "syscon"
+managing the common sram which can be shared by multiple modules.
+
+Example:
+ /*for Hi6220*/
+ sram: sram@fff80000 {
+ compatible = "hisilicon,hi6220-sramctrl", "syscon";
+ reg = <0x0 0xfff80000 0x0 0x12000>;
+ };
