media: mmp: Bring back registration of the device

2025-01-07T11:21:39Z

In commit 4af65141e38e ("media: marvell: cafe: Register V4L2 device earlier"), a call to v4l2_device_register() was moved away from mccic_register() into its caller, marvell/cafe's cafe_pci_probe(). This is not the only caller though -- there's also marvell/mmp. Add v4l2_device_register() into mmpcam_probe() to unbreak the MMP camera driver, in a fashion analogous to what's been done to the Cafe driver. Same for the teardown path.

media: platform: drop vb2_ops_wait_prepare/finish

2024-10-28T08:20:07Z

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks. Signed-off-by: Hans Verkuil Reviewed-by: Neil Armstrong # for meson-ge2d Acked-by: Andrzej Pietrasiewicz

media: Switch back to struct platform_driver::remove()

2024-10-12T14:28:25Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/media to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

media: Convert from tasklet to BH workqueue

2024-06-21T06:57:09Z

The only generic interface to execute asynchronously in the BH context is tasklet; however, it's marked deprecated and has some design flaws. To replace tasklets, BH workqueue support was recently added. A BH workqueue behaves similarly to regular workqueues except that the queued work items are executed in the BH context. This patch converts drivers/media/* from tasklet to BH workqueue. Based on the work done by Tejun Heo Signed-off-by: Allen Pais Signed-off-by: Hans Verkuil

media: v4l: Use correct dependency for camera sensor drivers

2023-09-14T10:38:17Z

The Kconfig option that enables compiling camera sensor drivers is VIDEO_CAMERA_SENSOR rather than MEDIA_CAMERA_SUPPORT as it was previously. Fix this. Also select VIDEO_OV7670 for marvell platform drivers only if MEDIA_SUBDRV_AUTOSELECT and VIDEO_CAMERA_SENSOR are enabled.

media: v4l: async: Set v4l2_device and subdev in async notifier init

2023-08-10T05:58:32Z

Set the v4l2_device already in async notifier init, so struct device related to it will be available before the notifier is registered. This requires separating notifier initialisation into two functions, one that takes v4l2_device as its argument, v4l2_async_nf_init and v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the notifier will use a single function, v4l2_async_nf_register. This is done in order to make struct device available earlier, during construction of the async connections, for sensible debug prints.
