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.
