net: ti: am65-cpsw-nuss: Add devlink support AM65 NUSS ethernet switch on K3 devices can be configured to work either in independent mac mode where each port acts as independent network interface (multi mac) or switch mode. Add devlink hooks to provide a way to switch b/w these modes. Rationale to use devlink instead of defaulting to bridge mode is that SoC use cases require to support multiple independent MAC ports with no switching so that users can use software bridges with multi-mac configuration (e.g: to support LAG, HSR/PRP, etc). Also, switching between multi mac and switch mode requires significant Port and ALE reconfiguration, therefore is easier to be made as part of mode change devlink hooks. It also allows to keep user interface similar to what was implemented for the previous generation of TI CPSW IP (on AM33/AM43/AM57 SoCs).

devlink: introduce flash update overwrite mask Sections of device flash may contain settings or device identifying information. When performing a flash update, it is generally expected that these settings and identifiers are not overwritten. However, it may sometimes be useful to allow overwriting these fields when performing a flash update. Some examples include, 1) customizing the initial device config on first programming, such as overwriting default device identifying information, or 2) reverting a device configuration to known good state provided in the new firmware image, or 3) in case it is suspected that current firmware logic for managing the preservation of fields during an update is broken. Although some devices are able to completely separate these types of settings and fields into separate components, this is not true for all hardware. To support controlling this behavior, a new DEVLINK_ATTR_FLASH_UPDATE_OVERWRITE_MASK is defined. This is an nla_bitfield32 which will define what subset of fields in a component should be overwritten during an update. If no bits are specified, or of the overwrite mask is not provided, then an update should not overwrite anything, and should maintain the settings and identifiers as they are in the previous image. If the overwrite mask has the DEVLINK_FLASH_OVERWRITE_SETTINGS bit set, then the device should be configured to overwrite any of the settings in the requested component with settings found in the provided image. Similarly, if the DEVLINK_FLASH_OVERWRITE_IDENTIFIERS bit is set, the device should be configured to overwrite any device identifiers in the requested component with the identifiers from the image. Multiple overwrite modes may be combined to indicate that a combination of the set of fields that should be overwritten. Drivers which support the new overwrite mask must set the DEVLINK_SUPPORT_FLASH_UPDATE_OVERWRITE_MASK in the supported_flash_update_params field of their devlink_ops.

devlink: support directly reading from region memory To read from a region, user space must currently request a new snapshot of the region and then read from that snapshot. This can sometimes be overkill if user space only reads a tiny portion. They first create the snapshot, then request a read, then destroy the snapshot. For regions which have a single underlying "contents", it makes sense to allow supporting direct reading of the region data. Extend the DEVLINK_CMD_REGION_READ to allow direct reading from a region if requested via the new DEVLINK_ATTR_REGION_DIRECT. If this attribute is set, then perform a direct read instead of using a snapshot. Direct read is mutually exclusive with DEVLINK_ATTR_REGION_SNAPSHOT_ID, and care is taken to ensure that we reject commands which provide incorrect attributes. Regions must enable support for direct read by implementing the .read() callback function. If a region does not support such direct reads, a suitable extended error message is reported.

mlxsw: Register physical ports as a devlink resource The switch ASIC has a limited capacity of physical ('flavour physical' in devlink terminology) ports that it can support. While each system is brought up with a different number of ports, this number can be increased via splitting up to the ASIC's limit. Expose physical ports as a devlink resource so that user space will have visibility to the maximum number of ports that can be supported and the current occupancy. In addition, add a "Generic Resources" section in devlink-resource documentation so the different drivers will be aligned by the same resource name when exposing to user space.

net/mlx5e: Add recovery flow for tx devlink health reporter for unhealthy PTP SQ A new check for the tx devlink health reporter is introduced for determining when the PTP port timestamping SQ is considered unhealthy. If there are enough CQEs considered never to be delivered, the space that can be utilized on the SQ decreases significantly, impacting performance and usability of the SQ. The health reporter is triggered when the number of likely never delivered port timestamping CQEs that utilize the space of the PTP SQ is greater than 93.75% of the total capacity of the SQ. A devlink health reporter recover method is also provided for this specific TX error context that restarts the PTP SQ.

devlink: convert driver-specific files to reStructuredText Several drivers document what parameters they support in a devlink-params-*.txt file. This file is supposed to contain both the list of generic parameters implemented by the driver, as well as a list of driver-specific parameters and their descriptions. It would also be good if the driver documentation included other driver-specific implementations, such as info versions, devlink regions, and so forth. Convert all of these documentation files to reStructuredText, and rename them to just the driver name. Future changes will include other driver-specific implementations. Each file will contain a table for the generic parameters implemented, as well as a separate table for the driver-specific parameters. Future sections such as for devlink info versions will be added to these files.
