ARM: pxa: tosa: switch to gpio-charger
Switch to simpler gpio-charger module. PDA power requires additional setup in platform file and is more suited for boards with separate AC and USB charging inputs. Tosa has a unified input, so it's better suited for gpio-charger. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
