+Each device which generates interrupts must have an 'interrupt'
+property. The interrupt property value is an arbitrary number of
+of 'interrupt specifier' values which describe the interrupt or
+interrupts for the device.
+
+The encoding of an interrupt specifier is determined by the
+interrupt domain in which the device is located in the
+interrupt tree. The root of an interrupt domain specifies in
+its #interrupt-cells property the number of 32-bit cells
+required to encode an interrupt specifier. See the OF interrupt
+mapping documentation for a detailed description of domains.
+
+For example, the binding for the OpenPIC interrupt controller
+specifies an #interrupt-cells value of 2 to encode the interrupt
+number and level/sense information. All interrupt children in an
+OpenPIC interrupt domain use 2 cells per interrupt in their interrupts
+property.
+
+The PCI bus binding specifies a #interrupt-cell value of 1 to encode
+which interrupt pin (INTA,INTB,INTC,INTD) is used.
+
+2) interrupt-parent property
+----------------------------
+
+The interrupt-parent property is specified to define an explicit
+link between a device node and its interrupt parent in
+the interrupt tree. The value of interrupt-parent is the
+phandle of the parent node.
+
+If the interrupt-parent property is not defined for a node, it's
+interrupt parent is assumed to be an ancestor in the node's
+_device tree_ hierarchy.
+
+3) OpenPIC Interrupt Controllers
+--------------------------------
+
+OpenPIC interrupt controllers require 2 cells to encode
+interrupt information. The first cell defines the interrupt
+number. The second cell defines the sense and level
+information.
+
+Sense and level information should be encoded as follows:
+
+ 0 = low to high edge sensitive type enabled
+ 1 = active low level sensitive type enabled
+ 2 = active high level sensitive type enabled
+ 3 = high to low edge sensitive type enabled
+
+4) ISA Interrupt Controllers
+----------------------------
+
+ISA PIC interrupt controllers require 2 cells to encode
+interrupt information. The first cell defines the interrupt
+number. The second cell defines the sense and level
+information.
+
+ISA PIC interrupt controllers should adhere to the ISA PIC
+encodings listed below:
+
+ 0 = active low level sensitive type enabled
+ 1 = active high level sensitive type enabled
+ 2 = high to low edge sensitive type enabled
+ 3 = low to high edge sensitive type enabled
+

+ to get notified the temp has exceeded a range. With this option off,
+ a timer is used to re-check the temperature periodically.
+
+ However, on some cpus it appears that the TAU interrupt hardware
+ is buggy and can cause a situation which would lead unexplained hard

/*
* thermal support for the cell processor
*
+ * This module adds some sysfs attributes to cpu and spu nodes.
+ * Base for measurements are the digital thermal sensors (DTS)
+ * located on the chip.
+ * The accuracy is 2 degrees, starting from 65 up to 125 degrees celsius
+ * The attributes can be found under
+ * /sys/devices/system/cpu/cpuX/thermal
+ * /sys/devices/system/spu/spuX/thermal
+ *
+ * The following attributes are added for each node:
+ * temperature:
+ * contains the current temperature measured by the DTS
+ * throttle_begin:
+ * throttling begins when temperature is greater or equal to
+ * throttle_begin. Setting this value to 125 prevents throttling.
+ * throttle_end:
+ * throttling is being ceased, if the temperature is lower than
+ * throttle_end. Due to a delay between applying throttling and
+ * a reduced temperature this value should be less than throttle_begin.
+ * A value equal to throttle_begin provides only a very little hysteresis.
+ * throttle_full_stop:
+ * If the temperatrue is greater or equal to throttle_full_stop,
+ * full throttling is applied to the cpu or spu. This value should be
+ * greater than throttle_begin and throttle_end. Setting this value to
+ * 65 prevents the unit from running code at all.
