The Renesas Ethernet Switch has three independent ports. Each port can
act as a separate interface, and can be enabled or disabled
independently. Currently all ports are enabled by default, hence board
DTS files that enable the switch must disable all unused ports
explicitly.
Disable all ports by default, and explicitly enable ports that are used,
next to their configuration.

different switches
There are different switches available on both the RZ/G3S SMARC Module and
RZ SMARC Carrier II boards. These switches are used to route different SoC
signals to different parts available on board.
These switches are described in device trees through macros. These macros
are set accordingly such that the resulted compiled dtb to describe the
on-board switches states.
The SCIF1 depends on the state of the SW_CONFIG3 and SW_OPT_MUX4 switches.
SCIF1 can be enabled through a device tree overlay. To manage all switches
in a unified state and allow users to configure the output device tree, add
a file that contains all switch definitions and states.
Commit prepares the code to enable SCIF1 on the RZ/G3S overlay.

Each rswitch port TSNn has a dedicated MAC address assigned to it, so
does AVB MAC. The MAC addresses for each rswitch port and AVB, four in
total, are stored in the FPGA populated on the board and can be read out
via I2C from bus i2c@e66e0000 address 0x70 offsets 0x58 for AVB and
0x60, 0x68, 0x70 for TSNn.
There is no single MAC address assigned to the rswitch itself, there are
three of them, one for each rswitch port. Instead of ethernet0 alias
for rswitch itself, describe aliases ethernet0, ethernet1 for each
enabled rswitch port. This allows U-Boot to insert MAC addresses from
its environment variables ethaddr/eth1addr/eth2addr into each rswitch
port nodes, so Linux can read and use one unique MAC address for each
rswitch port.
Note that it is unlikely this would break existing rswitch driver
operation in the Linux kernel, because as of right now, the rswitch
driver already calls of_get_ethdev_address() for each port to read
out the MAC address of each rswitch port DT node. If that is missing,
it falls back to MAC address settings read from the hardware itself.
If that also fails, it uses a random MAC address.

When describing the PHYs connected to AVB1 and AVB2, mdio nodes will be
needed to describe the connections, and each mdio node will need to
contain these two properties instead. This will make the #address-cells
and #size-cells described in the base SoC include file redundant and
they will produce warnings, remove them.
In an effort to keep all three AVB nodes style consistent add an mdio
node to AVB0 already described and rename the phy node to better
describe the PHY that is connected to AVB0 before adding more PHYs.

Pull kvm fixes from Paolo Bonzini:
"ARM:
- Large set of fixes for vector handling, especially in the
interactions between host and guest state.
This fixes a number of bugs affecting actual deployments, and
greatly simplifies the FP/SIMD/SVE handling. Thanks to Mark Rutland
for dealing with this thankless task.
- Fix an ugly race between vcpu and vgic creation/init, resulting in
unexpected behaviours
- Fix use of kernel VAs at EL2 when emulating timers with nVHE
- Small set of pKVM improvements and cleanups
x86:
- Fix broken SNP support with KVM module built-in, ensuring the PSP
module is initialized before KVM even when the module
infrastructure cannot be used to order initcalls
- Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being
emulated by KVM to fix a NULL pointer dereference
- Enter guest mode (L2) from KVM's perspective before initializing
the vCPU's nested NPT MMU so that the MMU is properly tagged for
L2, not L1
- Load the guest's DR6 outside of the innermost .vcpu_run() loop, as
the guest's value may be stale if a VM-Exit is handled in the
fastpath"

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull trace ring buffer fixes from Steven Rostedt:
- Enable resize on mmap() error
When a process mmaps a ring buffer, its size is locked and resizing
is disabled. But if the user passes in a wrong parameter, the mmap()
can fail after the resize was disabled and the mmap() exits with
error without reenabling the ring buffer resize. This prevents the
ring buffer from ever being resized after that. Reenable resizing of
the ring buffer on mmap() error.
- Have resizing return proper error and not always -ENOMEM
If the ring buffer is mmapped by one task and another task tries to
resize the buffer it will error with -ENOMEM. This is confusing to
the user as there may be plenty of memory available. Have it return
the error that actually happens (in this case -EBUSY) where the user
can understand why the resize failed.
- Test the sub-buffer array to validate persistent memory buffer
On boot up, the initialization of the persistent memory buffer will
do a validation check to see if the content of the data is valid, and
if so, it will use the memory as is, otherwise it re-initializes it.
There's meta data in this persistent memory that keeps track of which
sub-buffer is the reader page and an array that states the order of
the sub-buffers. The values in this array are indexes into the
sub-buffers. The validator checks to make sure that all the entries
in the array are within the sub-buffer list index, but it does not
check for duplications.
While working on this code, the array got corrupted and had
duplicates, where not all the sub-buffers were accounted for. This
passed the validator as all entries were valid, but the link list was
incorrect and could have caused a crash. The corruption only produced
incorrect data, but it could have been more severe. To fix this,
create a bitmask that covers all the sub-buffer indexes and set it to
all zeros. While iterating the array checking the values of the array
content, have it set a bit corresponding to the index in the array.
If the bit was already set, then it is a duplicate and mark the
buffer as invalid and reset it.
- Prevent mmap()ing persistent ring buffer
The persistent ring buffer uses vmap() to map the persistent memory.
Currently, the mmap() logic only uses virt_to_page() to get the page
from the ring buffer memory and use that to map to user space. This
works because a normal ring buffer uses alloc_page() to allocate its
memory. But because the persistent ring buffer use vmap() it causes a
kernel crash.
Fixing this to work with vmap() is not hard, but since mmap() on
persistent memory buffers never worked, just have the mmap() return
-ENODEV (what was returned before mmap() for persistent memory ring
buffers, as they never supported mmap. Normal buffers will still
allow mmap(). Implementing mmap() for persistent memory ring buffers
can wait till the next merge window.
- Fix polling on persistent ring buffers
There's a "buffer_percent" option (default set to 50), that is used
to have reads of the ring buffer binary data block until the buffer
fills to that percentage. The field "pages_touched" is incremented
every time a new sub-buffer has content added to it. This field is
used in the calculations to determine the amount of content is in the
buffer and if it exceeds the "buffer_percent" then it will wake the
task polling on the buffer.
As persistent ring buffers can be created by the content from a
previous boot, the "pages_touched" field was not updated. This means
that if a task were to poll on the persistent buffer, it would block
even if the buffer was completely full. It would block even if the
"buffer_percent" was zero, because with "pages_touched" as zero, it
would be calculated as the buffer having no content. Update
pages_touched when initializing the persistent ring buffer from a
previous boot.
