[PATCH v2 0/5] media: atomisp: Add support for v4l2-async sensor registration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

Here is a new version of my v4l2-async sensor registration support
for atomisp. I have merged all the prep / cleanup patches which Andy
already gave his Reviewed-by for in my media-atomisp branch:

https://git.kernel.org/pub/scm/linux/kernel/git/hansg/linux.git/log/?h=media-atomisp

This v2 series applies on top of that branch!

This v2 series is the remainder (and core part) of
my previous 2 related patch-series:

https://lore.kernel.org/linux-media/20230518153733.195306-1-hdegoede@xxxxxxxxxx/
https://lore.kernel.org/linux-media/20230518153214.194976-1-hdegoede@xxxxxxxxxx/

The big change in this v2 is making atomisp_csi2_bridge_init() also
add the ACPI GPIO mappings to the sensors it finds / it is adding
fwnode graph endpoints for. Combined with making sensor drivers
check there is a fwnode graph endpoint (and return -EPROBE_DEFER if not)
before trying to get GPIOs so that the mappings are in place before
getting the GPIOs.

Thank you Sakari for suggesting this nice solution.

Patch 1    Adds the v4l2-async sensor registration support
Patch 2-3  Convert the ov2680 and gc0310 drivers to this
Patch 4    Removes some now dead code
Patch 5    Moves the now fully standard / no custom atomisp API
           gc0310 sensor driver to drivers/media/i2c

Patches 1-4 only touch atomisp code and build on top of previous
work so I plan to merge these through my media-atomisp branch.

Patch 5 also depends on all the others, so it should also
get merged through my media-atomisp branch. Sakari may I have
your Ack for this ?  Alternatively we could delay the move to
the next kernel cycle and then it could be merged directly
into some other linux-media branch. Either way works for me.

Regards,

Hans
