system/core/init/init.cpp SetUsbController picks the first udc device if
there're multiple udc devices present on the system to populate
sys.usb.controller system property.
CONFIG_USB_DUMMY_HCD enabled in kernel-5.10 GKI would introduce a
dummy udc device named "dummy_udc.0". Depends on timing, the dummy
device might be picked up by the init process and incorrectly populate
sys.usb.controller.
This issue only applies to devices on kernel-5.10 GKI, the WAR is to
overwrite the sysprop if it's incorrectly populated by the dummy udc.

After USB enumeration, some SD card readers do not send signals to the
device when the SD card is inserted or removed.
To support SD card hotplugging, this patch enables in-kernel
media-presence polling, which will check the SD card status every 2
seconds after a SD card reader is attached.

Many host applications expect and ask for lower resolution streams when
streaming from a USB webcam. To support those applications, this CL
adds support for 640x480 and 640x360 streams.
Bug: 301170431
Test: Manually tested that the resolution is advertised and streamed.

Write to /sys/class/typec/port<...>/device/update_sdp_enum_timeout
to reduce SDP enumeration timeout value when device is in charger
mode. This will enable faster detection of a DCP port.
Test: Validate (in charger mode) that the sysfs attribute is 1
(meaning lower sdp timeout value is being used). Read dmesg to
see print showing timeout value is 5000ms.

Files created by the uvc driver gives write permissions to 'other' by
default. This permission is not needed at runtime. To minimize write
privileges, this CL removes other-write permission from all uvc config
files that had it.
Bug: 242344229
Test: Manually verified that no files have other-write permissions

The UVC gadget requires some setup in configfs before it can be used by
the gadget HAL. This CL adds that setup to usb specific init.rc file.
Currently, UVC is setup to advertise mjpeg streams at 720p and 1080p at
60, 30, 24, and 15 fps each.
Bug: 242344221
Test: Manually tested that UVC is correctly set up on boot.

Since retry times of kernel driver are 24 during USB enumeration,
the total time of bad USB enumeration will waste 48 seconds.
This patch will reduce the timeout from 2 seconds to 500ms, so the
total time is changed to 12 seconds.

Currently, USB gadgdet hal couldn't access configfs nodes during
device booting. The permission of configfs nodes are root as default,
and they are modified to system by init process. Therefore, USB
gadget HAL can't access them before permission changes completely.
The patch will modify permission of USB gadget hal so that it can
access configfs nodes without permission change.
