+Broadcom Secure Monitor Bounce buffer
+-----------------------------------------------------
+This binding defines the location of the bounce buffer
+used for non-secure to secure communications.
+
+Required properties:
+- compatible : "bcm,kona-smc"
+- reg : Location and size of bounce buffer
+
+Example:
+       smc@0x3404c000 {
+               compatible = "bcm,bcm11351-smc", "bcm,kona-smc";
+               reg = <0x3404c000 0x400>; //1 KiB in SRAM
+       };

                      <0x3ff00100 0x100>;
        };
 
+       smc@0x3404c000 {
+               compatible = "bcm,bcm11351-smc", "bcm,kona-smc";
+               reg = <0x3404c000 0x400>; //1 KiB in SRAM
+       };

        uart@3e000000 {
                compatible = "bcm,bcm11351-dw-apb-uart", "snps,dw-apb-uart";
