* These are mostly useful for debugging purposes so I've added them
in the project's utilities wiki page.
* alsa-utils have been renamed to use their original names if there's no
conflict with other packages in AOSP.
* Can be used to write partition images to a storage device that has the
correct partition structure after flashing an image created by mkimg.sh.
* Poor man's alternative to
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot erase userdata
* When 'jack' is selected using the property, first PCM card that has name
'Headphones' is used.
When 'dac' is selected, first PCM card that is not named 'Headphones',
'vc4hdmi0', or 'vc4hdmi1' is used.
* It's always been intended that changing audio output devices requires
a reboot. Get the PCM card and device once when the HAL is initialized.
Might save a few ms on start_output_stream.
* It's always been intended that changing audio output devices requires
a reboot. Get the ALSA device once when the HAL is initialized.
Might save a few ms on start_output_stream.
* HIDL services are not included on API level 35. Add the services since
we're still using few HIDL HALs.

* FCM level can't be bumped to 202404 until all HALs have been updated to
AIDL i.e. at least following HALs reported by 'make check-vintf-all'.
All HALs in device manifest are declared in FCM <= level 202404

The following instances are in the device manifest but not specified in framework compatibility matrix:
android.hardware.camera.provider@2.5::ICameraProvider/legacy/0
* Needed for AIDL HDMI-CEC HAL to work. Some functions that were in the
HIDL HDMI-CEC HAL have been moved to separate HDMI connection HAL in the
AIDL versions. Only returns connection status of HDMI ports on Pi.
onHotplugEvent is not implemented.
* Use hardware/interfaces/tv/hdmi/connection/aidl/ as reference.
* Use vendor property to allow labeling it for SELinux.
* Remove unneeded properties to set version and vendor id. Using the
default values in any case.
* Start the service later at 'class hal' to avoid making this into bootstrap
APEX. 'class early_hal' is started on trigger 'on late-fs' which is too
early for vendor APEX.
* Pi 5 has independent cards for DSI-0, DSI-1, DPI, and VEC.
In theory we could have two DSI displays so add two more entries.
