+Amlogic Meson8 and Meson8b power-management-unit:
+-------------------------------------------------
+
+The pmu is used to turn off and on different power domains of the SoCs
+This includes the power to the CPU cores.
+
+Required node properties:
+- compatible value : depending on the SoC this should be one of:
+ "amlogic,meson8-pmu"
+ "amlogic,meson8b-pmu"
+- reg : physical base address and the size of the registers window
+
+Example:
+
+ pmu@c81000e4 {
+ compatible = "amlogic,meson8b-pmu", "syscon";
+ reg = <0xc81000e0 0x18>;
+ };

+Amlogic Meson8 and Meson8b SRAM for smp bringup:
+------------------------------------------------
+
+Amlogic's SMP-capable SoCs use part of the sram for the bringup of the cores.
+Once the core gets powered up it executes the code that is residing at a
+specific location.
+
+Therefore a reserved section sub-node has to be added to the mmio-sram
+declaration.
+
+Required sub-node properties:
+- compatible : depending on the SoC this should be one of:
+ "amlogic,meson8-smp-sram"
+ "amlogic,meson8b-smp-sram"
+
+The rest of the properties should follow the generic mmio-sram discription
+found in ../../misc/sram.txt
+
+Example:
+
+ sram: sram@d9000000 {
+ compatible = "mmio-sram";
+ reg = <0xd9000000 0x20000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0xd9000000 0x20000>;
+
+ smp-sram@1ff80 {
+ compatible = "amlogic,meson8b-smp-sram";
+ reg = <0x1ff80 0x8>;
+ };
+ };
