lost power, the POR will consume too much memory at mounting, this
process may be very slow due to a large number of swapping.

The DWC2 driver auto detects the hardware and enable
the gadget descriptor DMA if the DWC2 IP supports it.
However, the gadget descriptor DMA has some unexpected
compatibility issues, so we use buffer DMA instead of
desc DMA.

v2 tuning will inherit pre-stage loader's phase
settings for the first time, and do re-tune if
necessary. Re-tune will still try the rough degrees,
for instance, 90, 180, 270, 360 but continue to do the
fine tuning if sample window isn't good enough.

it would not put any burden on the normal driver process but
just ensure it has a dead-line weapon to fight for any issues
preventing the IP to work normally.

commit aaf4b964e66f ("Add CONFIG_PSI to recommended")
This feature is not (yet?) required for Go, so we need to put it in
'recommended'.
commit 5f92c3d69791 ("android R: replace CONFIG_MEMCG requirement with CONFIG_PSI")
With adoption of PSI events as low memory notification mechanism MEMCG
becomes optional and PSI becomes mandatory. Note that MEMCG can still be
used for instance in Android Go devices but it's not mandatory anymore.

As we know, The framebased format can be used to support a lot of
formats other than YUV and MJPEG, for example: H264 or H265.
And Nowadays, the H264 and H265 is used more and more compared to the
MJPEG, so there is a need to support such usecase, although the new UVC
1.5 and the UVC1.1 extensions already support H264, but they are much
more expensive and most of the time, what we need is just a channel to
stream the video frames.
In this patch, we implement the framebased format and set it to H264 by
default, and the users could change the video format as they need through
the guid configfs attribute node.

Several macros used to define attributes and their access functions take
multiple arguments to specify endianness and string conversion
functions, based on the size of the attribute. This can be simplified by
passing the number of bits explicitly, and constructing the name of the
functions internally.
The UVCG_OPTS_ATTR macro can be simplified further as all fields it
deals with are unsigned int.

USB descriptors are stored in little endian, requiring the use of
conversion macros. Those macros are incorrectly used for values stored
in native endian structures within the driver. Operation on big endian
platforms is thus broken. Fix it by removing the conversion macros where
they're not needed.

(cherry picked from commit 78c9e7ce00)
- Add bFrameIndex as a UVCG_FRAME_ATTR_RO for each frame size.
- Automatically assign ascending bFrameIndex to each frame in a format.
Before all "bFrameindex" attributes were set to "1" with no way to
configure the gadget otherwise. This resulted in the host always
negotiating for bFrameIndex 1 (i.e. the first frame size of the gadget).
After the negotiation the host driver will set the user or application
selected frame size, while the gadget is actually set to the first frame
size.
Now, when the containing format is linked into the streaming header,
iterate over all child frame descriptors and assign ascending indices.
The automatically assigned indices can be read from the new read only
bFrameIndex configfs attribute in each frame descriptor item.

(cherry picked from commit b206548be6)
The UVC format description are numbered using the descriptor's
bFormatIndex field. The index is used in UVC requests, and is thus
needed to handle requests in userspace. Make it dynamically discoverable
by exposing it in a bFormatIndex configfs attribute of the uncompressed
and mjpeg format config items.
The bFormatIndex value exposed through the attribute is stored in the
config item private data. However, that value is never set: the driver
instead computes the bFormatIndex value when linking the stream class
header in the configfs hierarchy and stores it directly in the class
descriptors in a separate structure. In order to expose the value
through the configfs attribute, store it in the config item private data
as well. This results in a small code simplification.

(cherry picked from commit 61ff10e0ea)
The video control and video streaming interface numbers are needed in
the UVC gadget userspace stack to reply to UVC requests. They are
hardcoded to fixed values at the moment, preventing configurations with
multiple functions.
To fix this, make them dynamically discoverable by userspace through
read-only configfs attributes in <function>/control/bInterfaceNumber and
<function>/streaming/bInterfaceNumber respectively.
