Right now exynos is exposing DPI as a TMDS encoder and VGA connector,
which seems rather misleading. This isn't just an internal detail,
since xrandr actually exposes "VGA" as the output name. Define some
new enums so that vc4's DPI can have a more informative name.
I considered other names for the connector as well. For VC4, the
Adafruit DPI kippah takes the 28 GPIO pins and routes them to a
standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely
identify an ordering of pins (apparently some other orderings exist),
doesn't explain things as well for the user (who, if anything, knows
their product is a DPI kippah/panel combo), and actually doesn't have
to exist (one could connect the 28 GPIOs directly to something else).
Simply "DPI" seems like a good compromise name to distinguish from the
HDMI, DSI, and TV connectors .

This adds debugfs consumer for xHCI driver. The debugfs entries
read all host registers, device/endpoint contexts, command ring,
event ring and various endpoint rings. With these entries, users
can check the registers and memory spaces used by a host during
run time, or save all the information with a simple 'cp -r' for
post-mortem programs.
The file hierarchy looks like this.

(cherry picked from commit 121dcf1190)
This patch creates a new event class called xhci_log_ring, and
defines the events used for tracing the change of all kinds of
rings used by an xhci host. An xHCI ring is basically a memory
block shared between software and hardware. By tracing changes
of rings, it makes the life easier for debugging hardware or
software problems.
This info can be used, later, to print, in a human readable way,
the life cycle of an xHCI ring using the trace-cmd tool and the
appropriate plugin.

There is a bt power issue on Debian OS, the blueman app
will callback to enable the bluetooth power during the bringup.
As below log the system bringup about 10s.
[BT_RFKILL]: rfkill_rk_set_power: set bt wake_host pin output high!
[BT_RFKILL]: rfkill_rk_set_power: enable bt reset pin!
[BT_RFKILL]: ENABLE UART_RTS

So the rfkill-bt driver should judge the power status, otherwise the
