====================
net: ethernet: ti: am65-cpsw: add multi port support in mac-only mode

This series adds multi-port support in mac-only mode (multi MAC mode) to TI
AM65x CPSW driver in preparation for enabling support for multi-port devices,
like Main CPSW0 on K3 J721E SoC or future CPSW3g on K3 AM64x SoC.

The multi MAC mode is implemented by configuring every enabled port in "mac-only"
mode (all ingress packets are sent only to the Host port and egress packets
directed to target Ext. Port) and creating separate net_device for
every enabled Ext. port.

This series does not affect on existing CPSW2g one Ext. Port devices and xmit
path changes are done only for multi-port devices by splitting xmit path for
one-port and multi-port devices.

Patches 1-3: Preparation patches to improve K3 CPSW configuration depending on DT
Patches 4-5: Fix VLAN offload for multi MAC mode
Patch 6: Fixes CPTS context lose issue during PM runtime transition
Patch 7: Fixes TX csum offload for multi MAC mode
Patches 8-9: add multi-port support to TI AM65x CPSW
Patch 10: handle deferred probe with new dev_err_probe() API

changes in v3:
- rebased
- added Reviewed-by: Jesse Brandeburg <jesse.brandeburg@intel.com>
- added Patch 10 which is minor optimization

changes in v2:
- patch 8: xmit path split for one-port and multi-port devices to avoid
performance losses
- patch 9: fixed the case when Port 1 is disabled
- Patch 7: added fix for TX csum offload

This patch adds final multi-port support to TI AM65x CPSW driver path in
preparation for adding support for multi-port devices, like Main CPSW0 on
K3 J721E SoC or future CPSW3g on K3 AM64x SoC.
- the separate netdev is created for every enabled external Port;
- DMA channels are common/shared for all external Ports and the RX/TX NAPI
and DMA processing assigned to first available netdev;
- external Ports are configured in mac-only mode, which is similar to TI
"dual-mac" mode for legacy TI CPSW - packets are sent to the Host port only
in ingress and directly to the Port on egress. No packet switching between
external ports happens.
- every port supports the same features as current AM65x CPSW on external
device.

K3 J721E SoC or future CPSW3g on K3 AM64x SoC.
Hence DMA channels are common/shared for all ext Ports and the RX/TX NAPI
and DMA processing going to be assigned to first available netdev this patch:
- ensures all RX descriptors fields are initialized;
- adds synchronization for TX DMA push/pop operation (locking) as
Networking core locks are not enough any more;
- updates TX bql processing for every packet in
am65_cpsw_nuss_tx_compl_packets() as every completed TX skb can have
different ndev assigned (come from different netdevs).

To avoid performance issues for existing one-port CPSW2g devices the above
changes are done only for multi-port devices by splitting xmit path for
one-port and multi-port devices.

net: ethernet: ti: am65-cpsw: fix tx csum offload for multi mac mode

The current implementation uses .ndo_set_features() callback to track
NETIF_F_HW_CSUM feature changes and update generic
CPSW_P0_CONTROL_REG.RX_CHECKSUM_EN option accordingly. It's not going to
work in case of multi-port devices as TX csum offload can be changed per
netdev.

On K3 CPSWxG devices TX csum offload enabled in the following way:

- the CPSW_P0_CONTROL_REG.RX_CHECKSUM_EN option enables TX csum offload in
generic and affects all TX DMA channels and packets;

- corresponding fields in TX DMA descriptor have to be filed properly when
upper layer wants to offload TX csum (skb->ip_summed == CHECKSUM_PARTIAL)
and it's per-packet option.

The Linux Network core is expected to never request TX csum offload if
netdev NETIF_F_HW_CSUM feature is disabled, and, as result, TX DMA
descriptors should not be modified, and per-packet TX csum offload will be
disabled (or enabled) on per-netdev basis. Which, in turn, makes it safe to
enable the CPSW_P0_CONTROL_REG.RX_CHECKSUM_EN option unconditionally.

Hence, fix TX csum offload for multi-port devices by:
- enabling the CPSW_P0_CONTROL_REG.RX_CHECKSUM_EN option in
am65_cpsw_nuss_common_open() unconditionally
- and removing .ndo_set_features() callback implementation, which was used
only NETIF_F_HW_CSUM feature update purposes

In case CPTS is enabled it's initialized during probe and does not expect

net: ethernet: ti: am65-cpsw: fix vlan offload for multi mac mode

The VLAN offload for AM65x CPSW2G is implemented using existing ALE APIs,
which are also used by legacy CPSW drivers.
So, now it always adds current Ext. Port and Host as VLAN members when VLAN
is added by 8021Q core (.ndo_vlan_rx_add_vid) and forcibly removes VLAN
from ALE table in .ndo_vlan_rx_kill_vid(). This works as for AM65x CPSW2G
(which has only one Ext. Port) as for legacy CPSW devices (which can't
support same VLAN on more then one Port in multi mac (dual-mac) mode). But
it doesn't work for the new J721E and AM64x multi port CPSWxG versions
doesn't have such restrictions and allow to offload the same VLAN on any
number of ports.

Now the attempt to add same VLAN on two (or more) K3 CPSWxG Ports will
cause:
- VLAN members mask overwrite when VLAN is added
- VLAN removal from ALE table when any Port removes VLAN

This patch fixes an issue by:
- switching to use cpsw_ale_vlan_add_modify() instead of
cpsw_ale_add_vlan() when VLAN is added to ALE table, so VLAN members
mask will not be overwritten;
- Updates cpsw_ale_del_vlan() as:
if more than one ext. Port is in VLAN member mask
then remove only current port from VLAN member mask
else remove VLAN ALE entry

Example:
add: P1 | P0 (Host) -> members mask: P1 | P0
add: P2 | P0 -> members mask: P2 | P1 | P0
rem: P1 | P0 -> members mask: P2 | P0
rem: P2 | P0 -> members mask: -

The VLAN is forcibly removed if port_mask=0 passed to cpsw_ale_del_vlan()
to preserve existing legacy CPSW drivers functionality.

Merge tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:

- Add redirect_neigh() BPF packet redirect helper, allowing to limit
stack traversal in common container configs and improving TCP
back-pressure.

Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.

- Expand netlink policy support and improve policy export to user
space. (Ge)netlink core performs request validation according to
declared policies. Expand the expressiveness of those policies
(min/max length and bitmasks). Allow dumping policies for particular
commands. This is used for feature discovery by user space (instead
of kernel version parsing or trial and error).

- Support IGMPv3/MLDv2 multicast listener discovery protocols in
bridge.

- Allow more than 255 IPv4 multicast interfaces.

- Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
packets of TCPv6.

- In Multi-patch TCP (MPTCP) support concurrent transmission of data on
multiple subflows in a load balancing scenario. Enhance advertising
addresses via the RM_ADDR/ADD_ADDR options.

- Support SMC-Dv2 version of SMC, which enables multi-subnet
deployments.

- Allow more calls to same peer in RxRPC.

- Support two new Controller Area Network (CAN) protocols - CAN-FD and
ISO 15765-2:2016.

- Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
kernel problem.

- Add TC actions for implementing MPLS L2 VPNs.

- Improve nexthop code - e.g. handle various corner cases when nexthop
objects are removed from groups better, skip unnecessary
notifications and make it easier to offload nexthops into HW by
converting to a blocking notifier.

- Support adding and consuming TCP header options by BPF programs,
opening the doors for easy experimental and deployment-specific TCP
option use.

- Reorganize TCP congestion control (CC) initialization to simplify
life of TCP CC implemented in BPF.

- Add support for shipping BPF programs with the kernel and loading
them early on boot via the User Mode Driver mechanism, hence reusing
all the user space infra we have.

- Support sleepable BPF programs, initially targeting LSM and tracing.

- Add bpf_d_path() helper for returning full path for given 'struct
path'.

- Make bpf_tail_call compatible with bpf-to-bpf calls.

- Allow BPF programs to call map_update_elem on sockmaps.

- Add BPF Type Format (BTF) support for type and enum discovery, as
well as support for using BTF within the kernel itself (current use
is for pretty printing structures).

- Support listing and getting information about bpf_links via the bpf
syscall.

- Enhance kernel interfaces around NIC firmware update. Allow
specifying overwrite mask to control if settings etc. are reset
during update; report expected max time operation may take to users;
support firmware activation without machine reboot incl. limits of
how much impact reset may have (e.g. dropping link or not).

- Extend ethtool configuration interface to report IEEE-standard
counters, to limit the need for per-vendor logic in user space.

- Adopt or extend devlink use for debug, monitoring, fw update in many
drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx,
dpaa2-eth).

- In mlxsw expose critical and emergency SFP module temperature alarms.
Refactor port buffer handling to make the defaults more suitable and
support setting these values explicitly via the DCBNL interface.

- Add XDP support for Intel's igb driver.

- Support offloading TC flower classification and filtering rules to
mscc_ocelot switches.

- Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
fixed interval period pulse generator and one-step timestamping in
dpaa-eth.

- Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
offload.

- Add Lynx PHY/PCS MDIO module, and convert various drivers which have
this HW to use it. Convert mvpp2 to split PCS.

- Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
7-port Mediatek MT7531 IP.

- Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
and wcn3680 support in wcn36xx.

- Improve performance for packets which don't require much offloads on
recent Mellanox NICs by 20% by making multiple packets share a
descriptor entry.

- Move chelsio inline crypto drivers (for TLS and IPsec) from the
crypto subtree to drivers/net. Move MDIO drivers out of the phy
directory.

- Clean up a lot of W=1 warnings, reportedly the actively developed
subsections of networking drivers should now build W=1 warning free.

- Make sure drivers don't use in_interrupt() to dynamically adapt their
code. Convert tasklets to use new tasklet_setup API (sadly this
conversion is not yet complete).

Merge series "Support ROHM BD9576MUF and BD9573MUF PMICs" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:

Initial support for ROHM BD9576MUF and BD9573MUF PMICs.

These PMICs are primarily intended to be used to power the R-Car family
processors. BD9576MUF includes some additional safety features the
BD9573MUF does not have. This initial version of drivers does not
utilize these features and for now the SW behaviour is identical.

Please note that this version of drivers is only tested on BD9576MUF
but according to the data-sheets the relevant parts of registers should
be same so drivers should also work on BD9573MUF.

This patch series includes MFD, watchdog and regulator drivers with
basic functionality such as:

- Enabling and pinging the watchdog
- configuring watchog timeout / window from device-tree
- reading regulator states/voltages
- enabling/disabling VOUT1 (VD50) when control mode B is used.

This patch series does not bring interrupt support. BD9576MUF and BD9573MUF
are designed to keep the IRQ line low for whole duration of error
condition. IRQ can't be 'acked'. So proper IRQ support would require
some IRQ limiter implementation (delayed unmask?) in order to not hog
the CPU.
