title: Freescale i.MX8qxp Display Controller interrupt controller

description: |
  The Display Controller has a built-in interrupt controller with the following
  features for all relevant HW events:
 
  * Enable bit (mask)
  * Status bit (set by an HW event)
  * Preset bit (can be used by SW to set status)
  * Clear bit (used by SW to reset the status)
 
  Each interrupt can be connected as IRQ (maskable) and/or NMI (non-maskable).
  Alternatively the un-masked trigger signals for all HW events are provided,
  allowing it to use a global interrupt controller instead.
 
  Each interrupt can be protected against SW running in user mode. In that case,
  only privileged AHB access can control the interrupt status.
