According to v4l2 request api specifications, it's allowed to skip control if its content isn't changed for performance reasons. Cedrus driver predates that, so it has implemented mechanism to check if all required controls are included in one request. Conform to specifications with removing that mechanism. Note that this mechanism with static required flag isn't very good anyway because need for control is usually signaled in other controls.

Commit 3d1387b3 ("media: vidtv: fix some warnings") replaced the unused flexible array member at the end of struct vidtv_mpeg_ts with a pointer. This broke the 188-byte alignment since the struct no longer was 4 bytes in size. Fix this by removing this field entirely. Fixes: 3d1387b3 ("media: vidtv: fix some warnings") Signed-off-by:

In preparation for adding suspend/resume hooks, factor out the hardware initialization from the driver probe/remove functions. The timeout programmed during init is taken from the `struct rc_dev` so it is maintained across an exit/init cycle. This resolves some trivial issues with the probe function: throwing away the error from clk_prepare_enable and using the wrong type for the temporary register value. It also fixes the order of the remove function to unregister the RC device before turning off the hardware. This prevents userspace from triggering register writes (via LIRC_SET_REC_TIMEOUT) while the hardware is disabled. Acked-by:

Currently on platforms designed for Windows, connections between CIO2 and sensors are not properly defined in DSDT. This patch extends the ipu3-cio2 driver to compensate by building software_node connections, parsing the connection properties from the sensor's SSDB buffer.

To ensure we handle situations in which multiple sensors of the same model (and therefore _HID) are present in a system, we need to be able to iterate over devices matching a known _HID but unknown _UID and _HRV - add acpi_dev_get_next_match_dev() to accommodate that possibility and change acpi_dev_get_first_match_dev() to simply call the new function with a NULL starting point. Add an iterator macro for convenience. Reviewed-by:

This implements the remaining .graph_*() callbacks in the fwnode operations structure for the software nodes. That makes the fwnode_graph_*() functions available in the drivers also when software nodes are used. The implementation tries to mimic the "OF graph" as much as possible, but there is no support for the "reg" device property. The ports will need to have the index in their name which starts with "port@" (for example "port@0", "port@1", ...) and endpoints will use the index of the software node that is given to them during creation. The port nodes can also be grouped under a specially named "ports" subnode, just like in DT, if necessary. The remote-endpoints are reference properties under the endpoint nodes that are named "remote-endpoint". Reviewed-by:

OF, ACPI and software_nodes all implement graphs including nodes for ports and endpoints. These are all intended to be named with a common schema, as "port@n" and "endpoint@n" where n is an unsigned int representing the index of the node. To ensure commonality across the subsystems, provide a set of macros to define the format. Suggested-by:
