What: /sys/class/regulator/.../state
Date: April 2008
KernelVersion: 2.6.26
Contact: Liam Girdwood <lg@opensource.wolfsonmicro.com>
Description:
Each regulator directory will contain a field called
state. This holds the regulator output state.

This will be one of the following strings:

'enabled'
'disabled'
'unknown'

'enabled' means the regulator output is ON and is supplying
power to the system.

'disabled' means the regulator output is OFF and is not
supplying power to the system..

'unknown' means software cannot determine the state.

NOTE: this field can be used in conjunction with microvolts
and microamps to determine regulator output levels.

Description:
Each regulator directory will contain a field called
type. This holds the regulator type.

This will be one of the following strings:

'voltage'
'current'
'unknown'

'voltage' means the regulator output voltage can be controlled
by software.

'current' means the regulator output current limit can be
controlled by software.

'unknown' means software cannot control either voltage or
current limit.

It is advised, but not required that you turn on the
CONFIG_FRAME_POINTER kernel option. This option inserts code to

registers or on the stack at different points which will allow a
debugger such as gdb to more accurately construct stack back traces
while debugging the kernel.

If the architecture that you are using supports the kernel option
CONFIG_DEBUG_RODATA, you should consider turning it off. This
option will prevent the use of software breakpoints because it
marks certain regions of the kernel's memory space as read-only.
If kgdb supports it for the architecture you are using, you can
use hardware breakpoints if you desire to run with the
CONFIG_DEBUG_RODATA option turned on, else you need to turn off
this option.
