The DB8500 PRCMU communicates directly and autonomously with the AB8500 and thus it appears as a subnode of the DB8500 PRCMU. An altered version called AB8505 also exist, the difference in AB8505 is that some of the USB and USB charging handling has changed, and it has an embedded USB-to-serial converter. Most subblocks takes their interrupts directly from the AB8500 embedded interrupt controller. properties: $nodename: pattern: '^ab850[05]$' compatible: enum: - stericsson,ab8500 - stericsson,ab8505 interrupts: maxItems: 1 interrupt-controller: true '#interrupt-cells': const: 2 # Some subnodes use a reg, some don't.
