Fixes this smatch warning: drivers/media/usb/dvb-usb-v2/rtl28xxu.c:1040 rtl2832u_frontend_attach() warn: missing error code 'ret' It is actually a bogus warning since in this particular case ret isn't meant to be set. But by reworking the code a bit the code is actually a lot more understandable and it fixes this warning. 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. [Sakari Ailus: Make cio2_bridge_init static inline to a fix compiler warning, wrapped a bunch of long lines.] Suggested-by:

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:

Daniel Scally authored
Registering software_nodes with the .parent member set to point to a currently unregistered software_node has the potential for problems, so enforce parent -> child ordering in arrays passed in to software_node_register_nodes(). Software nodes that are children of another software node should be unregistered before their parent. To allow easy unregistering of an array of software_nodes ordered parent to child, reverse the order in which software_node_unregister_nodes() unregisters software_nodes. Suggested-by:

This function is used to find fwnode endpoints against a device. In some instances those endpoints are software nodes which are children of fwnode->secondary. Add support to fwnode_graph_get_endpoint_by_id() to find those endpoints by recursively calling itself passing the ptr to fwnode->secondary in the event no endpoint is found for the primary.

Some types of fwnode_handle do not implement the device_is_available() check, such as those created by software_nodes. There isn't really a meaningful way to check for the availability of a device that doesn't actually exist, so if the check isn't implemented just assume that the "device" is present. Suggested-by:

Convert video-interfaces.txt to DT schema. As it contains a mixture of device level and endpoint properties, split it up into 2 schemas. Binding schemas will need to reference both the graph.yaml and video-interfaces.yaml schemas. The exact schema depends on how many ports and endpoints for the binding. A single port with a single endpoint looks similar to this: port: $ref: /schemas/graph.yaml#/$defs/port-base properties: endpoint: $ref: video-interfaces.yaml# unevaluatedProperties: false properties: bus-width: enum: [ 8, 10, 12, 16 ] pclk-sample: true hsync-active: true vsync-active: true required: - bus-width additionalProperties: false Acked-by:Jacopo Mondi <jacopo@jmondi.org> Acked-by:
