-PPC4xx Clock Power Management (CPM) node
-
-Required properties:
-	- compatible		: compatible list, currently only "ibm,cpm"
-	- dcr-access-method	: "native"
-	- dcr-reg		: < DCR register range >
-
-Optional properties:
-	- er-offset		: All 4xx SoCs with a CPM controller have
-				  one of two different order for the CPM
-				  registers. Some have the CPM registers
-				  in the following order (ER,FR,SR). The
-				  others have them in the following order
-				  (SR,ER,FR). For the second case set
-				  er-offset = <1>.
-	- unused-units		: specifier consist of one cell. For each
-				  bit in the cell, the corresponding bit
-				  in CPM will be set to turn off unused
-				  devices.
-	- idle-doze		: specifier consist of one cell. For each
-				  bit in the cell, the corresponding bit
-				  in CPM will be set to turn off unused
-				  devices. This is usually just CPM[CPU].
-	- standby		: specifier consist of one cell. For each
-				  bit in the cell, the corresponding bit
-				  in CPM will be set on standby and
-				  restored on resume.
-	- suspend		: specifier consist of one cell. For each
-				  bit in the cell, the corresponding bit
-				  in CPM will be set on suspend (mem) and
-				  restored on resume. Note, for standby
-				  and suspend the corresponding bits can
-				  be different or the same. Usually for
-				  standby only class 2 and 3 units are set.
-				  However, the interface does not care.
-				  If they are the same, the additional
-				  power saving will be seeing if support
-				  is available to put the DDR in self
-				  refresh mode and any additional power
-				  saving techniques for the specific SoC.

-Example:
-	CPM0: cpm {
-		compatible = "ibm,cpm";
-		dcr-access-method = "native";
-		dcr-reg = <0x160 0x003>;
-		er-offset = <0>;
-		unused-units = <0x00000100>;
-		idle-doze = <0x02000000>;
-		standby = <0xfeff0000>;
-		suspend = <0xfeff791d>;
-};
