+
+description: |
+ The ICS525 and ICS307 oscillators are produced by Integrated
+ Devices Technology (IDT). ARM integrated these oscillators deeply into their
+ reference designs by adding special control registers that manage such
+ oscillators to their system controllers.
+
+ The various ARM system controllers contain logic to serialize and initialize
+ an ICST clock request after a write to the 32 bit register at an offset
+ into the system controller. Furthermore, to even be able to alter one of
+ these frequencies, the system controller must first be unlocked by
+ writing a special token to another offset in the system controller.
+
+ Some ARM hardware contain special versions of the serial interface that only
+ connects the low 8 bits of the VDW (missing one bit), hard-wires RDW to
+ different values and sometimes also hard-wires the output divider. They
+ therefore have special compatible strings as per this table (the OD value is
+ the value on the pins, not the resulting output divider).
+
+ In the core modules and logic tiles, the ICST is a configurable clock fed
+ from a 24 MHz clock on the motherboard (usually the main crystal) used for
+ generating e.g. video clocks. It is located on the core module and there is
+ only one of these. This clock node must be a subnode of the core module.
