Pull ARM SoC updates from Olof Johansson:
"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"

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.

The Tegra210 (and earlier) driver now supports all the functionality
that the Tegra186 (and later) driver does, so they can be unified.
Note that previously the Tegra186 (and later) driver could be unloaded,
even if that was perhaps not very useful. Older chips don't support that
yet, but once they do this code can be reenabled.

The current per-SoC setup code runs at a fairly arbitrary point during
probe, thereby making it less flexible for other SoC generations. Move
the call around slightly (after only the very basic, common setup that
applies to all SoC generations has been performed), which will allow
it to be used for other implementations.

As another step towards unifying both the Tegra210 (and earlier) and
Tegra186 (and later) memory controller drivers, unify the structures
that are used to represent them.
Note that this comes at a slight space penalty since some fields are
not used on all generations, but the benefits of unifying the driver
outweigh the downsides.

Add driver state syncing that is invoked once all PMC consumers are
attached and ready. The consumers are the power domain clients.
The synchronization callback is invoked once all client drivers are
probed, the driver core handles this for us. This callback informs
PMC driver that all voltage votes are initialized by each PD client
and it's safe to begin voltage scaling of the core power domain.

Pull networking updates from Jakub Kicinski:
"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)

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

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.

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().

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.

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.

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.

Add basic support for MRP. The HW will just trap all MRP frames on the
ring ports to CPU and allow the SW to process them. In this way it is
possible to for this node to behave both as MRM and MRC.
Current limitations are:
- it doesn't support Interconnect roles.
- it supports only a single ring.
- the HW should be able to do forwarding of MRP Test frames so the SW
will not need to do this. So it would be able to have the role MRC
without SW support.

For TX timestamping, we use the felix_txtstamp method which is common
with the regular (non-8021q) ocelot tagger. This method says that skb
deferral is needed, prepares a timestamp request ID, and puts a clone of
the skb in a queue waiting for the timestamp IRQ.
felix_txtstamp is called by dsa_skb_tx_timestamp() just before the
tagger's xmit method. In the tagger xmit, we divert the packets
classified by dsa_skb_tx_timestamp() as PTP towards the MMIO-based
injection registers, and we declare them as dead towards dsa_slave_xmit.
If not PTP, we proceed with normal tag_8021q stuff.
Then the timestamp IRQ fires, the clone queued up from felix_txtstamp is
matched to the TX timestamp retrieved from the switch's FIFO based on
the timestamp request ID, and the clone is delivered to the stack.
On RX, thanks to the VCAP IS2 rule that redirects the frames with an
EtherType for 1588 towards two destinations:
- the CPU port module (for MMIO based extraction) and
- if the "no XTR IRQ" workaround is in place, the dsa_8021q CPU port
the relevant data path processing starts in the ptp_classify_raw BPF
classifier installed by DSA in the RX data path (post tagger, which is
completely unaware that it saw a PTP packet).
This time we can't reuse the same implementation of .port_rxtstamp that
also works with the default ocelot tagger. That is because felix_rxtstamp
is given an skb with a freshly stripped DSA header, and it says "I don't
need deferral for its RX timestamp, it's right in it, let me show you";
and it just points to the header right behind skb->data, from where it
unpacks the timestamp and annotates the skb with it.
The same thing cannot happen with tag_ocelot_8021q, because for one
thing, the skb did not have an extraction frame header in the first
place, but a VLAN tag with no timestamp information. So the code paths
in felix_rxtstamp for the regular and 8021q tagger are completely
independent. With tag_8021q, the timestamp must come from the packet's
duplicate delivered to the CPU port module, but there is potentially
complex logic to be handled [ and prone to reordering ] if we were to
just start reading packets from the CPU port module, and try to match
them to the one we received over Ethernet and which needs an RX
timestamp. So we do something simple: we tell DSA "give me some time to
think" (we request skb deferral by returning false from .port_rxtstamp)
and we just drop the frame we got over Ethernet with no attempt to match
it to anything - we just treat it as a notification that there's data to
be processed from the CPU port module's queues. Then we proceed to read
the packets from those, one by one, which we deliver up the stack,
timestamped, using netif_rx - the same function that any driver would
use anyway if it needed RX timestamp deferral. So the assumption is that
we'll come across the PTP packet that triggered the CPU extraction
notification eventually, but we don't know when exactly. Thanks to the
VCAP IS2 trap/redirect rule and the exclusion of the CPU port module
from the flooding replicators, only PTP frames should be present in the
CPU port module's RX queues anyway.
There is just one conflict between the VCAP IS2 trapping rule and the
semantics of the BPF classifier. Namely, ptp_classify_raw() deems
general messages as non-timestampable, but still, those are trapped to
the CPU port module since they have an EtherType of ETH_P_1588. So, if
the "no XTR IRQ" workaround is in place, we need to run another BPF
classifier on the frames extracted over MMIO, to avoid duplicates being
sent to the stack (once over Ethernet, once over MMIO). It doesn't look
like it's possible to install VCAP IS2 rules based on keys extracted
from the 1588 frame headers.

Since the felix DSA driver will need to poll the CPU port module for
extracted frames as well, let's create some common functions that read
an Extraction Frame Header, and then an skb, from a CPU extraction
group.
We abuse the struct ocelot_ops :: port_to_netdev function a little bit,
in order to retrieve the DSA port net_device or the ocelot switchdev
net_device based on the source port information from the Extraction
Frame Header, but it's all in the benefit of code simplification -
netdev_alloc_skb needs it. Originally, the port_to_netdev method was
intended for parsing act->dev from tc flower offload code.

The Injection Frame Header and Extraction Frame Header that the switch
prepends to frames over the NPI port is also prepended to frames
delivered over the CPU port module's queues.
Let's unify the handling of the frame headers by making the ocelot
driver call some helpers exported by the DSA tagger. Among other things,
this allows us to get rid of the strange cpu_to_be32 when transmitting
the Injection Frame Header on ocelot, since the packing API uses
network byte order natively (when "quirks" is 0).
The comments above ocelot_gen_ifh talk about setting pop_cnt to 3, and
the cpu extraction queue mask to something, but the code doesn't do it,
so we don't do it either.

We should not be unconditionally enabling address learning, since doing
that is actively detrimential when a port is standalone and not offloading
a bridge. Namely, if a port in the switch is standalone and others are
offloading the bridge, then we could enter a situation where we learn an
address towards the standalone port, but the bridged ports could not
forward the packet there, because the CPU is the only path between the
standalone and the bridged ports. The solution of course is to not
enable address learning unless the bridge asks for it.
We need to set up the initial port flags for no learning and flooding
everything, and also when the port joins and leaves the bridge.
The flood configuration was already configured ok for standalone mode
in ocelot_init, we just need to disable learning in ocelot_init_port.

There are several issues which may be seen when the link goes down while
forwarding traffic, all of which can be attributed to the fact that the
port flushing procedure from the reference manual was not closely
followed.
With flow control enabled on both the ingress port and the egress port,
it may happen when a link goes down that Ethernet packets are in flight.
In flow control mode, frames are held back and not dropped. When there
is enough traffic in flight (example: iperf3 TCP), then the ingress port
might enter congestion and never exit that state. This is a problem,
because it is the egress port's link that went down, and that has caused
the inability of the ingress port to send packets to any other port.
This is solved by flushing the egress port's queues when it goes down.
There is also a problem when performing stream splitting for
IEEE 802.1CB traffic (not yet upstream, but a sort of multicast,
basically). There, if one port from the destination ports mask goes
down, splitting the stream towards the other destinations will no longer
be performed. This can be traced down to this line:
ocelot_port_writel(ocelot_port, 0, DEV_MAC_ENA_CFG);
which should have been instead, as per the reference manual:
ocelot_port_rmwl(ocelot_port, 0, DEV_MAC_ENA_CFG_RX_ENA,
DEV_MAC_ENA_CFG);
Basically only DEV_MAC_ENA_CFG_RX_ENA should be disabled, but not
DEV_MAC_ENA_CFG_TX_ENA - I don't have further insight into why that is
the case, but apparently multicasting to several ports will cause issues
if at least one of them doesn't have DEV_MAC_ENA_CFG_TX_ENA set.
I am not sure what the state of the Ocelot VSC7514 driver is, but
probably not as bad as Felix/Seville, since VSC7514 uses phylib and has
the following in ocelot_adjust_link:
if (!phydev->link)
return;
therefore the port is not really put down when the link is lost, unlike
the DSA drivers which use .phylink_mac_link_down for that.
Nonetheless, I put ocelot_port_flush() in the common ocelot.c because it
needs to access some registers from drivers/net/ethernet/mscc/ocelot_rew.h
which are not exported in include/soc/mscc/ and a bugfix patch should
probably not move headers around.
