Signed-off-by: Steve Longerbeam --- Changes in v5: - imx_media_create_fwnode_pad_link() has been moved to core as v4l2_create_fwnode_links_to_pad(). Changes in v4: - none Changes in v3: - call a local imx-media utility imx_media_create_fwnode_pad_link(). Changes in v2: - Move notifier_to_csis_state() next to mipi_sd_to_csis_state(), remove unnecessary inline, and rename to mipi_notifier_to_csis_state().
