Having the '*' in the next line separated from the type makes it hard to see that these functions return a pointer to that type. Instead, keep it next to the type name so it is clear that it is a pointer to that type. Signed-off-by:

For debugging purposes, seeing the state integer representation is really inconvenient. Improve this and be developer-friendly by printing the state name instead. Suggested-by:

With legacy PM, drivers themselves were responsible for managing the device's power states and takes care of register states. After upgrading to the generic structure, PCI core will take care of required tasks and drivers should do only device-specific operations. The driver was invoking PCI helper functions like pci_save/restore_state() which is not recommended. Compile-Tested only. Signed-off-by:

When a notifier supplies a device fwnode and a subdev supplies an endpoint fwnode, incorrect matches may occur if multiple subdevs correspond to the same device fwnode. This can't be handled transparently in the framework, and requires the notifier to switch to endpoint fwnodes. Log a message to notify of this problem. A second message is added to help accelerating the transition to endpoint matching. Signed-off-by:

The notifier is useful to match functions to access information about the device matching a subdev. This will be used to print messages using the correct struct device and driver name. Signed-off-by:

Laurent Pinchart authored
fwnode matching was designed to match on nodes corresponding to a device. Some drivers, however, needed to match on endpoints, and have passed endpoint fwnodes to v4l2-async. This works when both the subdev and the notifier use the same fwnode types (endpoint or device), but makes drivers that use different types incompatible. Fix this by extending the fwnode match to handle fwnodes of different types. When the types (deduced from the presence of remote endpoints) are different, retrieve the device fwnode for the side that provides an endpoint fwnode, and compare it with the device fwnode provided by the other side. This allows interoperability between all drivers, regardless of which type of fwnode they use for matching. Signed-off-by:

Laurent Pinchart authored
Drivers may need to test if a fwnode is a graph endpoint. To avoid hand-written solutions that wouldn't work for all fwnode types, add a new fwnode_graph_is_endpoint() function for this purpose. We don't need to wire it up to different backends for OF and ACPI for now, as the implementation can simply be based on checkout the presence of a remote-endpoint property. Signed-off-by:

The MAX9286 is a 4-channel GMSL deserializer with coax or STP input and CSI-2 output. The device supports multicamera streaming applications, and features the ability to synchronise the attached cameras. CSI-2 output can be configured with 1 to 4 lanes, and a control channel is supported over I2C, which implements an I2C mux to facilitate communications with connected cameras across the reverse control channel.

Currently the 'pads' and 'pad_cfg' arrays of the rkisp1_resizer are of size 'RKISP1_ISP_PAD_MAX' which is 4. But the resizer has only two pads. Change the size of the arrays to 2 by adding and using 'RKISP1_RSZ_PAD_MAX' similar to the way it is done in the isp entity. [hverkuil: fix typos in commit log] Signed-off-by:

media: staging: rkisp1: cap: in stream start, replace calls to rkisp1_handle_buffer with rkisp1_set_next_buf The function 'rkisp1_stream_start' calls 'rkisp1_handle_buffer' in order to update the 'buf.curr' and 'buf.next' fields and configure the device before streaming starts. This cause a wrong increment of the debugs field 'frame_drop'. This patch replaces the call to 'rkisp1_handle_buffer' with a call to 'rkisp1_set_next_buf'. Signed-off-by:

The function 'rkisp1_set_next_buf' configures the registers according to 'cap->buf.next'. It is called after updating 'cap->buf.next' and 'cap->buf.curr'. This patch moves the code that updates those fields to rkisp1_set_next_buf. This is a preparation for later patch that change a call to 'rkisp1_handle_buffer' with a call to 'rkisp1_set_next_buf'.

The spinlock buf.lock should protect access to the buffers. This includes the buffers in buf.queue and also buf.curr and buf.next. The function 'rkisp1_set_next_buf' access buf.next therefore it should also be protected with the lock. Signed-off-by:

The function 'rkisp1_vb2_buf_queue' sets the next buffer directly in case the capture is already streaming but no frame yet arrived from the sensor. This is an optimization that tries to avoid dropping a frame. The call atomic_read(&cap->rkisp1->isp.frame_sequence) is used to check if a frame arrived. Reading the 'frame_sequence' should be avoided outside irq handlers to avoid race conditions. This patch removes this optimization. Dropping of the first frames can be avoided if userspace queues the buffers before start streaming. If userspace starts queueing buffers only after calling 'streamon' he risks frame drops anyway.
