1 year ago thank you for putting time to hunt this down.
Dell XPS 13 Plus 9320
I am unable to get camera to show anything. Chromium/firefox detects a camera as Intel MIPI Camera. Then it just shows black screen. Some seconds later it disappears(on chromium) saying it cannot detect camera even though it first detected and was showing black screen.

ASL Output: dsdt.dsl - 3301238 bytes
iASL Warning: There were 243 external control methods found during
disassembly, but only 499 were resolved (4294967040 unresolved). Additional
ACPI tables may be required to properly disassemble the code. This
resulting disassembler output file may not compile because the
disassembler did not know how many arguments to assign to the
unresolved methods. Note: SSDTs can be dynamically loaded at
runtime and may or may not be available via the host OS.
To specify the tables needed to resolve external control method
references, the -e option can be used to specify the filenames.
Example iASL invocations:
iasl -e ssdt1.aml ssdt2.aml ssdt3.aml -d dsdt.aml
iasl -e dsdt.aml ssdt2.aml -d ssdt1.aml
iasl -e ssdt*.aml -d dsdt.aml
In addition, the -fe option can be used to specify a file containing
control method external declarations with the associated method
argument counts. Each line of the file must be of the form:
External (<method pathname>, MethodObj, <argument count>)
Invocation:
iasl -fe refs.txt -d dsdt.aml$ grep -A4 '(CAM' dsdt.dsl

Recently a couple of PRs introduced support for Intel MIPI/IPU6 based webcams. (#212799, #225160, #225292)
As the upstream situation for these devices currently is a mess, this does not work on all devices.
This tracking issue should serve two purposes:
