When the usb gadget supporting for usb charger is ready, the usb charger
should get the type by the 'get_charger_type' callback which is implemented
by the usb gadget operations, and get the usb charger pointer from struct

This patch introduces the usb charger driver based on usb gadget that

The H3 has a usb-phy clk register which is similar to that of earlier
SoCs, but with support for a larger number of phys. So we can simply add

At least the EHCI found on the Allwinnner H3 SoC needs multiple reset
lines, the controller will not initialize while the reset for its
companion OHCI is still asserted, which means we need to de-assert
2 reset-controllers for this EHCI controller to work.

In some cases it is useful to be able to get a reset-controller by
index rather then by name. E.g. for a generic ip-block driver such
as the ehci-platform drivers which needs to support more then one reset,
without knowing the names of the reset lines (as that would make it

Background:
By configuring an instrument's event status register various
conditions can be reported via an SRQ notification. This complements
the synchronous polling approach using the READ_STATUS_BYTE ioctl
