+
+description:
+ the AB8500 "Analog Baseband" is the mixed-signals integrated circuit
+ handling power management (regulators), analog-to-digital conversion
+ (ADC), battery charging, fuel gauging of the battery, battery-backed
+ RTC, PWM, USB PHY and some GPIO lines in the ST-Ericsson U8500 platforms
+ in connection with the DB8500 digital baseband. 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.
