12description:
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.
