32# ppm configuration format
33#
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, PCIE, 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 match patterns to match devices
45# that fall into "domain_xxx", where wildcard '*' is allowed by observing
46# the following expectations:
47#	. a single wildcard with exact match up to (but exclude) the wildcard
48#	  which then terminates the match pattern;
49#	. a single wildcard that does not terminate a match pattern must
50#	  match driver name (followed by '@');
51#	. with two wildcard occurences, the first is to match driver name,
52#	  the second function id, as well as the last character of the match
53#	  pattern.
54#
55# "domain-xxx-ctrl" - blank space separated definitions in the form of
56# keyword=definition [keyword=definition...]
57#    The keywords are as follows, where 'method' must come before mask as it
58#       tells how to store 'mask' and 'val'.  Missing 'val' defaults to 0.
59#
60#    which keywords apply depends on cmd.  There are two sets as shown below.
61#    Here is the first:
62#	cmd=[CPU_GO | LED_ON | LED_OFF | FET_ON | FET_OFF | CLK_ON | CLK_OFF]
63# 	path=<prompath>	- control device's prom pathname (includes minor)
64# 	method=[KIO|I2CKIO]	This selects a method which may be
65#		an ioctl that sets a single value or an i2c ioctl that
66#		takes a value and a mask to access gpio register
67#	iord=<integer> - value of ioctl command for reading
68#	iowr=<integer> - value of ioctl command for writing
69# 	val=<integer>	- a single integer value, generally the value to which
70#			  the relevant bits of a register will be set
71#	mask=<integer>	- which bits of val are relevant (if method is I2CKIO)
72#
73#    Here is the second:
74#	cmd=[CPU_NEXT | PRE_CHNG | POST_CHNG]
75# 	path=<prompath>	   - control device's prom pathname, including minor
76# 	method=[CPUSPEEDKIO | VCORE]  This selects a method that uses
77#			     information like cpu speed index, value for
78#			     adjust cpu core voltage, delays, etc.
79#	iowr=<integer>     - value of ioctl write command
80#	speeds=<integer>   - indicates the number of cpu speeds that are
81#			     supported
