Take f_midi_bind() for example, when composite layer call it, it will
allocate hs descriptor by calling gadget_is_dualspeed() API to check
gadget max support speed capability, but most other gadget function didn't
do like this.
To follow other function drivers, it is safe to remove the check which
mean support all possible link speed by default in function driver.
Similar change apply to midi2 and uvc.
Also in midi and midi2, as there is no descriptor difference between
super speed and super speed plus, follow other gadget function drivers,
do not allocate descriptor for super speed plus, composite layer will
handle it properly.

(cherry picked from commit 46decc82ff)
For the userspace it is needed to distinguish between requests for the
control or streaming interface. The userspace would have to parse the
configfs to know which interface index it has to compare the ctrl
requests against. Since the interface numbers are not fixed, e.g. for
composite gadgets, the interface offset depends on the setup.
The kernel has this information when handing over the ctrl request to
the userspace. This patch removes the offset from the interface numbers
and expose the default interface defines in the uapi g_uvc.h.

(cherry picked from commit d182bf156c)
In the specification documents for the Uncompressed and MJPEG USB
Video Payloads, the field name is bmInterlaceFlags - it has been
misnamed within the kernel.
Although renaming the field does break the kernel's interface to
userspace it should be low-risk in this instance. The field is read
only and hardcoded to 0, so there was never any value in anyone
reading it. A search of the uvc-gadget application and all the
forks that I could find for it did not reveal any users either.

The layer sel configuration is exclusive for RV1126B, only one of
them can be set to 0b01 for either layer2_sel or layer1_sel when two
layers are displayed on the same time.
1. For RV1126B:
dsp_layer2_sel, that is top layer:
- 2'b00 WIN0 is top layer
- 2'b01 WIN2 is top layer
dsp_layer1_sel, that is bottom layer:
- 2'b00 WIN0 is bottom layer
- 2'b01 WIN2 is bottom layer
For {dsp_layer2_sel, dsp_layer1_sel}:
- 4'b0001 : WIN0 on the top, WIN2 on the bottom
- 4'b0100 : WIN2 on the top, WIN0 on the bottom
2. For other version:
- 2'b00 select WIN0
- 2'b10 select WIN2

1. Rockchip U-Boot will use kernel dtb by default.
2. The legacy U-Boot GPIO driver need regulator-boot-on in dtb to set
correct SDMMC0_PWREN value.
3. regulator-boot-on will not affect SDMMC0 function in kernel.
