net: mscc: ocelot: fix VCAP filters remaining active after being deleted
When ocelot_flower.c calls ocelot_vcap_filter_add(), the filter has a
given filter->id.cookie. This filter is added to the block->rules list.
However, when ocelot_flower.c calls ocelot_vcap_block_find_filter_by_id()
which passes the cookie as argument, the filter is never found by
filter->id.cookie when searching through the block->rules list.
This is unsurprising, since the filter->id.cookie is an unsigned long,
but the cookie argument provided to ocelot_vcap_block_find_filter_by_id()
is a signed int, and the comparison fails.

ARM: SoC updates for 5.15
There are three noteworthy updates for 32-bit arm platforms this time:
- The Microchip SAMA7 family based on Cortex-A7 gets introduced, a new
cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5 based)
SoCs.
- The ixp4xx platform (based on Intel XScale) is finally converted to
device tree, and all the old board files are getting removed now.
- The Cirrus Logic EP93xx platform loses support for the old
MaverickCrunch FPU. Support for compiling user space applications
was already removed in gcc-4.9, and the kernel support for old
applications could not be built with clang ias. After confirming
that there are no remaining users, removing this from the kernel
seemed better than adding support for unused features to clang.
There are minor updates to the aspeed, omap and samsung platforms

net: mscc: ocelot: convert to phylink
The felix DSA driver, which is a wrapper over the same hardware class as
ocelot, is integrated with phylink, but ocelot is using the plain PHY
library. It makes sense to bring together the two implementations, which
is what this patch achieves.
This is a large patch and hard to break up, but it does the following:
The existing ocelot_adjust_link writes some registers, and
felix_phylink_mac_link_up writes some registers, some of them are
common, but both functions write to some registers to which the other
doesn't.
The main reasons for this are:
- Felix switches so far have used an NXP PCS so they had no need to
write the PCS1G registers that ocelot_adjust_link writes
- Felix switches have the MAC fixed at 1G, so some of the MAC speed
changes actually break the link and must be avoided.
The naming conventions for the functions introduced in this patch are:
- vsc7514_phylink_{mac_config,validate} are specific to the Ocelot
instantiations and placed in ocelot_net.c which is built only for the
ocelot switchdev driver.
- ocelot_phylink_mac_link_{up,down} are shared between the ocelot
switchdev driver and the felix DSA driver (they are put in the common
lib).
One by one, the registers written by ocelot_adjust_link are:
DEV_MAC_MODE_CFG - felix_phylink_mac_link_up had no need to write this
register since its out-of-reset value was fine and
did not need changing. The write is moved to the
common ocelot_phylink_mac_link_up and on felix it is
guarded by a quirk bit that makes the written value
identical with the out-of-reset one
DEV_PORT_MISC - runtime invariant, was moved to vsc7514_phylink_mac_config
PCS1G_MODE_CFG - same as above
PCS1G_SD_CFG - same as above
PCS1G_CFG - same as above
PCS1G_ANEG_CFG - same as above
PCS1G_LB_CFG - same as above
DEV_MAC_ENA_CFG - both ocelot_adjust_link and ocelot_port_disable
touched this. felix_phylink_mac_link_{up,down} also
do. We go with what felix does and put it in
ocelot_phylink_mac_link_up.
DEV_CLOCK_CFG - ocelot_adjust_link and felix_phylink_mac_link_up both
write this, but to different values. Move to the common
ocelot_phylink_mac_link_up and make sure via the quirk
that the old values are preserved for both.
ANA_PFC_PFC_CFG - ocelot_adjust_link wrote this, felix_phylink_mac_link_up
did not. Runtime invariant, speed does not matter since
PFC is disabled via the RX_PFC_ENA bits which are cleared.
Move to vsc7514_phylink_mac_config.
QSYS_SWITCH_PORT_MODE_PORT_ENA - both ocelot_adjust_link and
felix_phylink_mac_link_{up,down} wrote
this. Ocelot also wrote this register
from ocelot_port_disable. Keep what
felix did, move in ocelot_phylink_mac_link_{up,down}
and delete ocelot_port_disable.
ANA_POL_FLOWC - same as above
SYS_MAC_FC_CFG - same as above, except slight behavior change. Whereas
ocelot always enabled RX and TX flow control, felix
listened to phylink (for the most part, at least - see
the 2500base-X comment).
The registers which only felix_phylink_mac_link_up wrote are:
SYS_PAUSE_CFG_PAUSE_ENA - this is why I am not sure that flow control
worked on ocelot. Not it should, since the
code is shared with felix where it does.
ANA_PORT_PORT_CFG - this is a Frame Analyzer block register, phylink
should be the one touching them, deleted.
Other changes:
- The old phylib registration code was in mscc_ocelot_init_ports. It is
hard to work with 2 levels of indentation already in, and with hard to
follow teardown logic. The new phylink registration code was moved
inside ocelot_probe_port(), right between alloc_etherdev() and
register_netdev(). It could not be done before (=> outside of)
ocelot_probe_port() because ocelot_probe_port() allocates the struct
ocelot_port which we then use to assign ocelot_port->phy_mode to. It
is more preferable to me to have all PHY handling logic inside the
same function.
- On the same topic: struct ocelot_port_private :: serdes is only used
in ocelot_port_open to set the SERDES protocol to Ethernet. This is
logically a runtime invariant and can be done just once, when the port
registers with phylink. We therefore don't even need to keep the
serdes reference inside struct ocelot_port_private, or to use the devm
variant of of_phy_get().
- Phylink needs a valid phy-mode for phylink_create() to succeed, and
the existing device tree bindings in arch/mips/boot/dts/mscc/ocelot_pcb120.dts
don't define one for the internal PHY ports. So we patch
PHY_INTERFACE_MODE_NA into PHY_INTERFACE_MODE_INTERNAL.
- There was a strategically placed:
switch (priv->phy_mode) {
case PHY_INTERFACE_MODE_NA:
continue;
which made the code skip the serdes initialization for the internal
PHY ports. Frankly that is not all that obvious, so now we explicitly
initialize the serdes under an "if" condition and not rely on code
jumps, so everything is clearer.
- There was a write of OCELOT_SPEED_1000 to DEV_CLOCK_CFG for QSGMII
ports. Since that is in fact the default value for the register field
DEV_CLOCK_CFG_LINK_SPEED, I can only guess the intention was to clear
the adjacent fields, MAC_TX_RST and MAC_RX_RST, aka take the port out
of reset, which does match the comment. I don't even want to know why
this code is placed there, but if there is indeed an issue that all
ports that share a QSGMII lane must all be up, then this logic is
already buggy, since mscc_ocelot_init_ports iterates using
for_each_available_child_of_node, so nobody prevents the user from
putting a 'status = "disabled";' for some QSGMII ports which would
break the driver's assumption.
In any case, in the eventuality that I'm right, we would have yet
another issue if ocelot_phylink_mac_link_down would reset those ports
and that would be forbidden, so since the ocelot_adjust_link logic did
not do that (maybe for a reason), add another quirk to preserve the
old logic.
The ocelot driver teardown goes through all ports in one fell swoop.
When initialization of one port fails, the ocelot->ports[port] pointer
for that is reset to NULL, and teardown is done only for non-NULL ports,
so there is no reason to do partial teardowns, let the central
mscc_ocelot_release_ports() do its job.
Tested bind, unbind, rebind, link up, link down, speed change on mock-up
hardware (modified the driver to probe on Felix VSC9959). Also
regression tested the felix DSA driver. Could not test the Ocelot
specific bits (PCS1G, SERDES, device tree bindings).

net: dsa: felix: stop calling ocelot_port_{enable,disable}
ocelot_port_enable touches ANA_PORT_PORT_CFG, which has the following fields: - LOCKED_PORTMOVE_CPU, LEARNDROP, LEARNCPU, LEARNAUTO, RECV_ENA, all of which are written with their hardware default values, also runtime invariants. So it makes no sense to write these during every .ndo_open. - PORTID_VAL: this field has an out-of-reset value of zero for all ports and must be initialized by software. Additionally, the ocelot_setup_logical_port_ids() code path sets up different logical port IDs for the ports in a hardware LAG, and we absolutely don't want .ndo_open to interfere there and reset those values. So in fact the write from ocelot_port_enable can better be moved to ocelot_init_port, and the .ndo_open hook deleted. ocelot_port_disable touches DEV_MAC_ENA_CFG and QSYS_SWITCH_PORT_MODE_PORT_ENA, in an attempt to undo what ocelot_adjust_link did. But since .ndo_stop does not get called each time the link falls (i.e. this isn't a substitute for .phylink_mac_link_down), felix already does better at this by writing those registers already in felix_phylink_mac_link_down. So keep ocelot_port_disable (for now, until ocelot is converted to phylink too), and just delete the felix call to it, which is not necessary.

ARM: SoC changes for 5.14
A few SoC (code) changes have queued up this cycle, mostly for minor
changes and some refactoring and cleanup of legacy platforms. This
branch also contains a few of the fixes that weren't sent in by the end
of the release (all fairly minor).
- Adding an additional maintainer for the TEE subsystem (Sumit Garg)
- Quite a significant modernization of the IXP4xx platforms by Linus
Walleij, revisiting with a new PCI host driver/binding, removing legacy
mach/* include dependencies and moving platform detection/config to
drivers/soc. Also some updates/cleanup of platform data.
- Core power domain support for Tegra platforms, and some improvements
in build test coverage by adding stubs for compile test targets.
- A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP
support on i.MX7D, SoC ID setup for i.MX50, removal of platform data
and board fixups for iMX6/7.
... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
Rockchip.

memory: tegra: Implement SID override programming
Instead of programming all SID overrides during early boot, perform the operation on-demand after the SMMU translations have been set up for a device. This reuses data from device tree to match memory clients for a device and programs the SID specified in device tree, which corresponds to the SID used for the SMMU context banks for the device.

Networking changes for 5.13.
Core:
- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to
walk all map elements in a more robust and easier to verify
fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection
- lpm: add support for batched ops in LPM trie
- add BTF_KIND_FLOAT support - mostly to allow use of BTF
on s390 which has floats in its headers files
- improve BPF syscall documentation and extend the use of kdoc
parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks
- xsk: build skb by page (aka generic zerocopy xmit) - improve
performance of software AF_XDP path by 33% for devices
which don't need headers in the linear skb part (e.g. virtio)
- nexthop: resilient next-hop groups - improve path stability
on next-hops group changes (incl. offload for mlxsw)
- ipv6: segment routing: add support for IPv4 decapsulation
- icmp: add support for RFC 8335 extended PROBE messages
- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is
slow in reporting that it completed transmitting the original
- tcp: reorder tcp_congestion_ops for better cache locality
- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR
- add reset option support for resetting one subflow
- udp: GRO L4 improvements - improve 'forward' / 'frag_list'
co-existence with UDP tunnel GRO, allowing the first to take
place correctly even for encapsulated UDP traffic
- micro-optimize dev_gro_receive() and flow dissection, avoid
retpoline overhead on VLAN and TEB GRO
- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls
- veth: allow GRO without XDP - this allows aggregating UDP
packets before handing them off to routing, bridge, OvS, etc.
- allow specifing ifindex when device is moved to another namespace
- netfilter:
- nft_socket: add support for cgroupsv2
- nftables: add catch-all set element - special element used
to define a default action in case normal lookup missed
- use net_generic infra in many modules to avoid allocating
per-ns memory unnecessarily
- xps: improve the xps handling to avoid potential out-of-bound
accesses and use-after-free when XPS change race with other
re-configuration under traffic
- add a config knob to turn off per-cpu netdev refcnt to catch
underflows in testing
Device APIs:
- add WWAN subsystem to organize the WWAN interfaces better and
hopefully start driving towards more unified and vendor-
-independent APIs
- ethtool:
- add interface for reading IEEE MIB stats (incl. mlx5 and
bnxt support)
- allow network drivers to dump arbitrary SFP EEPROM data,
current offset+length API was a poor fit for modern SFP
which define EEPROM in terms of pages (incl. mlx5 support)
- act_police, flow_offload: add support for packet-per-second
policing (incl. offload for nfp)
- psample: add additional metadata attributes like transit delay
for packets sampled from switch HW (and corresponding egress
and policy-based sampling in the mlxsw driver)
- dsa: improve support for sandwiched LAGs with bridge and DSA
- netfilter:
- flowtable: use direct xmit in topologies with IP
forwarding, bridging, vlans etc.
- nftables: counter hardware offload support
- Bluetooth:
- improvements for firmware download w/ Intel devices
- add support for reading AOSP vendor capabilities
- add support for virtio transport driver

- pci/iov: add sysfs MSI-X vector assignment interface
to distribute MSI-X resources to VFs (incl. mlx5 support)
New hardware/drivers:

- virtio:
- page_to_skb() use build_skb when there's sufficient tailroom
(21% improvement for 1000B UDP frames)
- support XDP even without dedicated Tx queues - share the Tx
queues with the stack when necessary
- mlx5:
- flow rules: add support for mirroring with conntrack,
matching on ICMP, GTP, flex filters and more

net: mscc: ocelot: support PTP Sync one-step timestamping
Although HWTSTAMP_TX_ONESTEP_SYNC existed in ioctl for hardware timestamp configuration, the PTP Sync one-step timestamping had never been supported. This patch is to truely support it. - ocelot_port_txtstamp_request() This function handles tx timestamp request by storing ptp_cmd(tx timestamp type) in OCELOT_SKB_CB(skb)->ptp_cmd, and additionally for two-step timestamp storing ts_id in OCELOT_SKB_CB(clone)->ptp_cmd. - ocelot_ptp_rew_op() During xmit, this function is called to get rew_op (rewriter option) by checking skb->cb for tx timestamp request, and configure to transmitting. Non-onestep-Sync packet with one-step timestamp request falls back to use two-step timestamp.

net: dsa: free skb->cb usage in core driver
Free skb->cb usage in core driver and let device drivers decide to use or not. The reason having a DSA_SKB_CB(skb)->clone was because dsa_skb_tx_timestamp() which may set the clone pointer was called before p->xmit() which would use the clone if any, and the device driver has no way to initialize the clone pointer. This patch just put memset(skb->cb, 0, sizeof(skb->cb)) at beginning of dsa_slave_xmit(). Some new features in the future, like one-step timestamp may need more bytes of skb->cb to use in dsa_skb_tx_timestamp(), and p->xmit().

issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as we
now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
- omap-prm driver needs to enable autoidle retention support for omap4
- omap5 clocks are missing gpmc and ocmc clock registers

net: ocelot: replay switchdev events when joining bridge
The premise of this change is that the switchdev port attributes and objects offloaded by ocelot might have been missed when we are joining an already existing bridge port, such as a bonding interface. The patch pulls these switchdev attributes and objects from the bridge, on behalf of the 'bridge port' net device which might be either the ocelot switch interface, or the bonding upper interface. The ocelot_net.c belongs strictly to the switchdev ocelot driver, while ocelot.c is part of a library shared with the DSA felix driver. The ocelot_port_bridge_leave function (part of the common library) used to call ocelot_port_vlan_filtering(false), something which is not necessary for DSA, since the framework deals with that already there. So we move this function to ocelot_switchdev_unsync, which is specific to the switchdev driver. The code movement described above makes ocelot_port_bridge_leave no longer return an error code, so we change its type from int to void.

net: ocelot: support multiple bridges
The ocelot switches are a bit odd in that they do not have an STP state to put the ports into. Instead, the forwarding configuration is delayed from the typical port_bridge_join into stp_state_set, when the port enters the BR_STATE_FORWARDING state. I can only guess that the implementation of this quirk is the reason that led to the simplification of the driver such that only one bridge could be offloaded at a time. We can simplify the data structures somewhat, and introduce a per-port bridge device pointer and STP state, similar to how the LAG offload works now (there we have a per-port bonding device pointer and TX enabled state). This allows offloading multiple bridges with relative ease, while still keeping in place the quirk to delay the programming of the PGIDs. We actually need this change now because we need to remove the bogus restriction from ocelot_bridge_stp_state_set that ocelot->bridge_mask needs to contain BIT(port), otherwise that function is a no-op.

RISC-V Patches for the 5.12 Merge Window
I have a handful of new RISC-V related patches for this merge window:
* A check to ensure drivers are properly using uaccess. This isn't
manifesting with any of the drivers I'm currently using, but may catch
errors in new drivers.
* Some preliminary support for the FU740, along with the HiFive
Unleashed it will appear on.
* NUMA support for RISC-V, which involves making the arm64 code generic.
* Support for kasan on the vmalloc region.
* A handful of new drivers for the Kendryte K210, along with the DT
plumbing required to boot on a handful of K210-based boards.
* Support for allocating ASIDs.
* Preliminary support for kernels larger than 128MiB.
* Various other improvements to our KASAN support, including the
utilization of huge pages when allocating the KASAN regions.
We may have already found a bug with the KASAN_VMALLOC code, but it's
passing my tests. There's a fix in the works, but that will probably
miss the merge window.

clk: Add RISC-V Canaan Kendryte K210 clock driver
Add a clock provider driver for the Canaan Kendryte K210 RISC-V SoC. This new driver with the compatible string "canaan,k210-clk" implements support for the full clock structure of the K210 SoC. Since it is required for the correct operation of the SoC, this driver is selected by default for compilation when the SOC_CANAAN option is selected. With this change, the k210-sysctl driver is turned into a simple platform driver which enables its power bus clock and triggers populating its child nodes. The sysctl driver retains the SOC early initialization code, but the implementation now relies on the new function k210_clk_early_init() provided by the new clk-k210 driver. The clock structure implemented and many of the coding ideas for the driver come from the work by Sean Anderson on the K210 support for the U-Boot project.
