7 title: ST-Ericsson Analog Baseband AB8500 and AB8505
10   - Linus Walleij <linus.walleij@linaro.org>
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
21   USB charging handling has changed, and it has an embedded USB-to-serial
23   AB8500 embedded interrupt controller.
