   12 description:
   13   the AB8500 "Analog Baseband" is the mixed-signals integrated circuit
   14   handling power management (regulators), analog-to-digital conversion
   15   (ADC), battery charging, fuel gauging of the battery, battery-backed
   16   RTC, PWM, USB PHY and some GPIO lines in the ST-Ericsson U8500 platforms
   17   in connection with the DB8500 digital baseband. The DB8500 PRCMU
   18   communicates directly and autonomously with the AB8500 and thus it
   19   appears as a subnode of the DB8500 PRCMU. An altered version called
   20   AB8505 also exist, the difference in AB8505 is that some of the USB and
   21   USB charging handling has changed, and it has an embedded USB-to-serial
   22   converter. Most subblocks takes their interrupts directly from the
   23   AB8500 embedded interrupt controller.
