Subject: [PATCH 0/2] media: intel-ipu3: allow the media graph to be used even if a subdev fails
Date: Tue, 4 Sep 2018 13:30:16 +0200 [thread overview]
Message-ID: <20180904113018.14428-1-javierm@redhat.com> (raw)
Hello,
This series allows the ipu3-cio2 driver to properly expose a subset of the
media graph even if some drivers for the pending subdevices fail to probe.
Currently the driver exposes a non-functional graph since the pad links are
created and the subdev dev nodes are registered in the v4l2 async .complete
callback. Instead, these operations should be done in the .bound callback.
Patch #1 just adds a v4l2_device_register_subdev_node() function to allow
registering a single device node for a subdev of a v4l2 device.
Patch #2 moves the logic of the ipu3-cio2 .complete callback to the .bound
callback. The .complete callback is just removed since is empy after that.
Best regards,
Javier
