This enables USB on the ARM juno board when booted with
an ACPI kernel. The PNP id comes from the PNP/ACPI registry
and describes an EHCI controller without debug.

This patch set enables USB on the ARM Juno development platform when
using an ACPI kernel.
First it adds an error message if the device cannot be configured with
the current DMA settings (missing/unsupported CCA attribute). It then
adds the ACPI PNP id to the acpi_match_table entry.

If the ehci driver fails to configure the dma settings then display
a dev error instead of simply failing. This is triggered in an
ACPI world if the user fails to set the _CCA on the device.

We initiate dwc2 usb controller in BIOS, dwc2_core_reset() should
be called before dwc2_get_hwparams() to reset core registers to
default value. Without this the FIFO setting might be incorrect
because calculating FIFO size need power-on value of
GRXFSIZ/GNPTXFSIZ/HPTXFSIZ registers.

The usb charger framework is based on usb gadget. The usb charger
need to be notified the state changing of usb gadget to confirm the
usb charger state.
Thus this patch adds a notifier mechanism for usb gadget to report a
event to usb charger when the usb gadget state is changed.

that requires a system with suitable hardware.
The basic conception of the usb charger is that, when one usb charger
is added or removed by reporting from the

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
