Previously this stayed unnoticed on Nexus 7 because pin control was enabled by default after rebooting from downstream kernel, which uses driver that enables the bit and charger registers are non-volatile until power supply (battery) is disconnected. Configure the pin control enable bit. This fixes the potentially never-enabled charging on devices that use pin control.

The interrupt should be disabled when the function is used outside of interrupt handler in order to prevent racing with the interrupt context. Add new parameter to smb347_set_writable() that allows to disable IRQ. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
