common information already populated in struct genl_info

- Extend and use the yaml devlink specs to [re]generate the split ops

Merge branch 'icssg-driver'

MD Danish Anwar says:

====================
Introduce ICSSG based ethernet Driver

The Programmable Real-time Unit and Industrial Communication Subsystem
Gigabit (PRU_ICSSG) is a low-latency microcontroller subsystem in the TI
SoCs. This subsystem is provided for the use cases like the implementation
of custom peripheral interfaces, offloading of tasks from the other
processor cores of the SoC, etc.

The subsystem includes many accelerators for data processing like
multiplier and multiplier-accumulator. It also has peripherals like
UART, MII/RGMII, MDIO, etc. Every ICSSG core includes two 32-bit
load/store RISC CPU cores called PRUs.

The above features allow it to be used for implementing custom firmware
based peripherals like ethernet.

This series adds the YAML documentation and the driver with basic EMAC
support for TI AM654 Silicon Rev 2 SoC with the PRU_ICSSG Sub-system.
running dual-EMAC firmware.
This currently supports basic EMAC with 1Gbps and 100Mbps link. 10M and
half-duplex modes are not yet supported because they require the support
of an IEP, which will be added later.
Advanced features like switch-dev and timestamping will be added later.

This is the v13 of the patch series [v1]. This version of the patchset
addresses comments made on v12.

There series doesn't have any dependency.

Changes from v12 to v13 :
*) Rebased the series on latest net-next.
*) Addressed Jakub's comments on ndo_xmit API. Now we will only stop queues
based on occupancy not on dma errors.
*) Removed limiting the number of serviced packets to budget for Tx NAPI.
Now Tx NAPI will keep servicing packets.
*) Removed netif_running() check when packet arrives.
*) Introduced prototypes of APIs in the same patch where these APIs are added.
Dropped __maybe_unused tags as compiler only cares about prototypes
existing, not whether actual callers are in place. Now prototypes of these
APIs are present in the same patch where they are introduced but thes APIs
are called later (in patch 6).

Changes from v11 to v12 :
*) Rebased the series on latest net-next.
*) Addressed Jakub's comments on ndo_xmit API.
*) Added hooks to .get_rmon_stats for the driver. Now tx / rx bucket size
and frame counts per bucket will be fetched by ethtool_rmon_stats instead
of ethtool -S.
*) Added __maybe_unused tags to unused config and classifier APIs in patch
2,3 and 4. These tags are later removed in patch 6.

Changes from v10 to v11 :
*) Rebased the series on latest net-next.
*) Split the ICSSG driver introduction patch into 9 different patches as
asked by Jakub.
*) Introduced new patch(patch 8/10) to dump Standard network interface
staticstics via ndo_get_stats64. Now certain stats that are reported by
ICSSG hardware and are also part of struct rtnl_link_stats64, will be
reported by ndo_get_stats64. While other stats that are not part of the
struct rtnl_link_stats64 will be reported by ethtool -S. These stats
are not duplicated.

Changes from v9 to v10 :
*) Rebased the series on latest net-next.
*) Moved 'ndev prueth->emac[mac] == emac' assignment to the end of function
prueth_netdev_init().
*) In unsupported phy_mode switch case instead of returning -EINVAL, store
the error code in ret and 'goto free'

Changes from v8 to v9 :
*) Rebased the series on latest net-next.
*) Fixed smatch and sparse warnings as pointed by Simon.
*) Fixed leaky ndev in prueth_netdev_init() as asked by Simon.

Changes from v7 to v8 :
*) Rebased the series on 6.5-rc1.
*) Fixed few formattings.

Changes from v6 to v7 :
*) Added RB tag of Rob in patch 1 of this series.
*) Addressed Simon's comment on patch 2 of the series.
*) Rebased patchset on next-20230428 linux-next.

Changes from v5 to v6 :
*) Added RB tag of Andrew Lunn in patch 2 of this series.
*) Addressed Rob's comment on patch 1 of the series.
*) Rebased patchset on next-20230421 linux-next.

Changes from v4 to v5 :
*) Re-arranged properties section in ti,icssg-prueth.yaml file.
*) Added requirement for minimum one ethernet port.
*) Fixed some minor formatting errors as asked by Krzysztof.
*) Dropped SGMII mode from enum mii_mode as SGMII mode is not currently
supported by the driver.
*) Added switch-case block to handle different phy modes by ICSSG driver.

Changes from v3 to v4 :
*) Addressed Krzysztof's comments and fixed dt_binding_check errors in
patch 1/2.
*) Added interrupt-extended property in ethernet-ports properties section.
*) Fixed comments in file icssg_switch_map.h according to the Linux coding
style in patch 2/2. Added Documentation of structures in patch 2/2.

Changes from v2 to v3 :
*) Addressed Rob and Krzysztof's comments on patch 1 of this series.
Fixed indentation. Removed description and pinctrl section from
ti,icssg-prueth.yaml file.
*) Addressed Krzysztof, Paolo, Randy, Andrew and Christophe's comments on
patch 2 of this seires.
*) Fixed blanklines in Kconfig and Makefile. Changed structures to const
as suggested by Krzysztof.
*) Fixed while loop logic in emac_tx_complete_packets() API as suggested
by Paolo. Previously in the loop's last iteration 'budget' was 0 and
napi_consume_skb would wrongly assume the caller is not in NAPI context
Now, budget won't be zero in last iteration of loop.
*) Removed inline functions addr_to_da1() and addr_to_da0() as asked by
Andrew.
*) Added dev_err_probe() instead of dev_err() as suggested by Christophe.
*) In ti,icssg-prueth.yaml file, in the patternProperties section of
ethernet-ports, kept the port name as "port" instead of "ethernet-port"
as all other drivers were using "port". Will change it if is compulsory
to use "ethernet-port".
