-Sleep specifiers:
+Clock nodes:
+The clock nodes are to describe the masks in PM controller registers for each
+soc clock.
+- fsl,pmcdr-mask: For "fsl,mpc8548-pmc"-compatible devices, the mask will be
+  ORed into PMCDR before suspend if the device using this clock is the wake-up
+  source and need to be running during low power mode; clear the mask if
+  otherwise.
 
-  fsl,mpc8349-pmc: Sleep specifiers consist of one cell.  For each bit
-  that is set in the cell, the corresponding bit in SCCR will be saved
-  and cleared on suspend, and restored on resume.  This sleep controller
-  supports disabling and resuming devices at any time.
+- fsl,sccr-mask: For "fsl,mpc8349-pmc"-compatible devices, the corresponding
+  bit specified by the mask in SCCR will be saved and cleared on suspend, and
+  restored on resume.
 
-  fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of
-  which will be ORed into PMCDR upon suspend, and cleared from PMCDR
-  upon resume.  The first two cells are as described for fsl,mpc8578-pmc.
-  This sleep controller only supports disabling devices during system
-  sleep, or permanently.
-
-  fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the
-  first of which will be ORed into DEVDISR (and the second into
-  DEVDISR2, if present -- this cell should be zero or absent if the
-  hardware does not have DEVDISR2) upon a request for permanent device
-  disabling.  This sleep controller does not support configuring devices
-  to disable during system sleep (unless supported by another compatible
-  match), or dynamically.
+- fsl,devdisr-mask: Contain one or two cells, depending on the availability of
+  DEVDISR2 register.  For compatible devices, the mask will be ORed into DEVDISR
+  or DEVDISR2 when the clock should be permenently disabled.
