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