The driver calls pci_set_mwi to enable memory-write-invalidate when it
is initialized, but does not call pci_clear_mwi when it is removed. Many
other drivers calls pci_clear_mwi when pci_set_mwi is called, such as

Structure, 'aic_reg_offset' describes for device specific register offset.
Each offset is used for IRQ chip operation. AIC and AIC5 have different
register values, but the structure can be shared.
Please note that this is not complete patch, it's a preceding step for
making unified AIC driver.

Currently the minimal up_threshold is 11, and user may want to
use a smaller minimal up_threshold for performance tuning,
so MIN_FREQUENCY_UP_THRESHOLD could be set to 1 because:
1. Current systems wouldn't be affected as they have already
a value >= 11.
2. New systems with a default kernel wou

Currently the Linux kernel does not provide any standard integration of this

that requires a system with suitable hardware.
The basic conception of the usb charger is that, when one usb charger

When the usb gadget supporting for usb charger is ready, the usb charger
