Hi All,
Here is v2 of my patch-series to make the atomisp code share the
ACPI -> sensor fwnode bridge code with the IPU3 (and IPU6 code).
The last 2 patches also rework VCM instantiation, which was my
initial reason for unifying / sharing the code.
Changes in v2:
- Rebase on top of f54eb0ac7c1a ("media: ipu3-cio2: rename cio2 bridge
to ipu bridge and move out of ipu3")
(rebase on top of sailus/media_tree.git/for-6.6-1.4-signed)
- Share the ipu_supported_sensors[] array between atomisp and IPU3/IPU6
(leave it in ipu-bridge.c instead of giving each consumer its own copy)
- 2 new bugfixes:
media: ipu-bridge: Fix null pointer deref on SSDB/PLD parsing warnings
media: ipu-bridge: Allow building as module
Original cover-letter:
While working on adding (proper) VCM support to the atomisp code
I found myself copying yet more code from
drivers/media/pci/intel/ipu3/cio2-bridge.c into the atomisp code.
So I decided that it really was time to factor out the common code
(most of the code) from intel/ipu3/cio2-bridge.c into its own
helper library and then share it between the atomisp and IPU3 code.
This will hopefully also be useful for the ongoing work to upstream
IPU6 input system support which also needs this functionality and
currently contains a 3th copy of this code in the out of tree driver.
This set consists of the following parts:
Patches 1-4 Bugfixes for recent changes
Patches 5-12 Cleanup / preparation patches
Patch 13 Drop ipu-bridge code copy from atomisp, switching to
the shared ipu-bridge module
Patch 14 Rework how VCM client instantiation is done so that
a device-link can be added from VCM to sensor to
fix issues with the VCM power-state being tied to
the sensor power state
Patch 15 Example patch to show how patch 11 avoids the need
for hacks in VCM drivers caused by the shared power state
(not intended for merging)
Regards,
Hans
