34# "ppm-domains" - in form of "domain_xxx" where "xxx" string highlights
35# the nature of the domain;
36#
37# "domain_xxx-model" - PM model: CPU, PCI, PCI_PROP, FET or LED.
38#
39# "domain_xxx-propname" - a property name that is exported by device in
40# a domain.  Currently, it is used by PCI_PROP model to identify devices
41# that are to have their clocks stopped when all power-manageable devices
42# in the domain are at D3 power level.
43#
44# "domain-xxx-devices" - a list of prom path(s) to include every devices
45# that fall into "domain_xxx", where wildcard '*' is allowed by following
46# the expectation:
47#
48# "domain-xxx-ctrl" - blank space separated definitions in form of
49# keyword=definition [keyword=definition...]
50#    The keywords are as follows, where 'method' must come before mask as it
51#       tells how to store 'mask' and 'val'.  Missing 'val' defaults to 0.
52#
53#    which keywords apply depend on cmd.  There are two sets as shown below.
54#    Here is the first:
55#	cmd=[CPU_GO | LED_ON | LED_OFF | FET_ON | FET_OFF | CLK_ON | CLK_OFF]
56# 	path=<prompath>	- control device's /devices pathname (includes minor)
57# 	method=[KIO|I2CKIO]	This selects a method which maybe
58#		an ioctl that sets a single value or an i2c ioctl that
59#		takes a value and a mask for access gpio register
60#	iord=<integer> - value of ioctl command for reading
61#	iowr=<integer> - value of ioctl command for writing
62# 	val=<integer>	- a single integer value, generally the value to which
63#			  to set the relevant bits of a register
64#	mask=<integer>	- which bits of val are relevant (if method is I2CKIO)
65#
66#    Here is the second:
67#	cmd=[CPU_NEXT | PRE_CHNG | POST_CHNG]
68# 	path=<prompath>	   - control device's prom pathname, including minor
69# 	method=[CPUSPEEDKIO | VCORE]  This selects a method that uses
70#			     information like cpu speed index, value for
71#			     adjust cpu core voltage, delays, etc.
72#	iowr=<integer>     - value of ioctl write command
73#	speeds=<integer>   - indicates the number of cpu speeds that are
74#			     supported
