Hi All,
Here is v3 of my patch-series to make the atomisp code share the
ACPI -> sensor fwnode bridge code with the IPU3 (and IPU6 code).
This series also rework VCM instantiation, which was my
initial reason for unifying / sharing the code.
Rafael, this v3 now includes a small ACPI patch:
ACPI: bus: Introduce acpi_match_acpi_device() function
It is probably easiest if you can give an ack for merging this
through the media tree. May we have your ack for this?
Sakari, I know that you have other pending patches depending
on this, patches 1-14 can be merged independent of the new
ACPI patch. Only the atomisp changes require that and those
can also be merged later.
Changes in v3:
- New patches:
media: i2c: Add driver for DW9719 VCM
ACPI: bus: Introduce acpi_match_acpi_device() function
media: atomisp: csi2-bridge: Add dev_name() to acpi_handle_info() logging
media: atomisp: csi2-bridge: Add support for VCM I2C-client instantiation
- media: atomisp: csi2-bridge: Switch to new common ipu_bridge_init():
- Add a table with per sensor-HID atomisp_sensor_config settings
for sensors which have lanes != 1 or which may have a VCM
(VCM support is added in a follow-up patch)
- Switch to acpi_handle_err() for logging errors
- Set orientation based on CSI link/port
This set now consists of the following parts:
Patches 1-4 Bugfixes for recent changes
Patches 5-12 Cleanup / preparation patches
Patch 13 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 14 Resubmit DW9719 VCM driver upstream now that Vsio hack is gone
Patch 15 New ACPI helper needed by atomisp bridge code
Patch 16 Drop ipu-bridge code copy from atomisp, switching to
the shared ipu-bridge module
Patch 17-18 Further atomisp bridge code improvements
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.
Regards,
Hans
