   12 description: |
   13   The i.MX SoC family has multiple buses for which clock frequency (and
   14   sometimes voltage) can be adjusted.
   15 
   16   Some of those buses expose register areas mentioned in the memory maps as GPV
   17   ("Global Programmers View") but not all. Access to this area might be denied
   18   for normal (non-secure) world.
   19 
   20   The buses are based on externally licensed IPs such as ARM NIC-301 and
   21   Arteris FlexNOC but DT bindings are specific to the integration of these bus
   22   interconnect IPs into imx SOCs.
