/dev/usb_ext_chg device file interface supports mmap and its current implementation allows any address for mapping. Fix it by mapping only charger block register address space. The user space does not need to pass any physical address in mmap. Implement an ioctl to tell the offset from which the first charger block register is available. User space adds this offset to the virtual address returned by mmap to access charger detection registers. The MSM_USB_EXT_CHG_INFO ioctl also returns the charger block type (QSCRATCH/ULPI) to user space. Use the ioctl interface for blocking low power mode while charger detection takes place in user space.
