Subject: [PATCH v2 0/3] media: v4l: async: add helper API v4l2_async_pad_init_and_register_subdev()
Date: Thu, 26 Feb 2026 17:55:25 -0500 [thread overview]
Message-ID: <20260226-v4l2_init_register-v2-0-902d7140f9fa@nxp.com> (raw)
Add the helper API v4l2_async_pad_init_and_register_subdev(), which
combines media_entity_pads_init(), v4l2_subdev_init_finalize(), and
v4l2_async_register_subdev() into a single call.
Reduce code duplication and simplify error handling in drivers.
Only change dwc and cdns. If agree add API, more driver can be simplified.
Signed-off-by: Frank Li <Frank.Li@nxp.com>

Changes in v2:
- Change API name to media_async_register_subdev()
- pass down __v4l2_async_register_subdev() as argument to extend more
support in future.
- Link to v1: https://lore.kernel.org/r/20260210-v4l2_init_register-v1-0-8fe43f7d349f@nxp.com
