50dec95c9d i3c: renesas: Fix out-of-bounds access for newdevs mask
When software initiates DAA (Dynamic Address Assignment), the controller
reports the result via the NRSPQP (Normal Response Queue Port Register).
The data length field of the response descriptor, which is accessible
through the NRSPQP register, indicates the number of devices remaining
after DAA. Consequently, when the bus is empty, this field contains the
maximum number of devices supported by the controller (8 for the Renesas
I3C controller).

Adjust the condition that computes the newly discovered devices bitmask
to prevent an out-of-bounds when the I3C bus is empty.

fbf26154c4 i3c: renesas: Perform Dynamic Address Assignment on resume
The Renesas RZ/G3S SoC supports a power saving mode where power to most
SoC components, including I3C, is turned off.

On systems where the I3C devices also loses power during suspend (e.g. NXP
P3T1085UK-ARD connected to the PMOD1_6A connector of the RZ SMARC Carrier
2 + Renesas RZ/G3S SMARC SOM), the devices becomes unreachable after
resume.

Running DAA in the controller resume path restores communication. However,
DAA relies on interrupts for TX/RX, which are not available in the noirq
suspend/resume phase (unless they are wakeup interrupts). For this, the
suspend/resume callbacks were moved out of the noirq phase. Currently,
there is no identified use case on either the Renesas RZ/G3S or Renesas
RZ/G3E SoCs that requires the controller suspend/resume hooks to be part of
the noirq suspend/resume phase.

Since renesas_i3c_reset() is not called anymore in atomic context
update it to use read_poll_timeout().

Along with this, struct renesas_i3c::DATBASn and its usage were removed,
as they are no longer needed.

Reset the controller on resume after enabling the clocks to follow the
same sequence as in probe and avoid potential ordering related failures.

With it, renesas_i3c_reset() was updated to use read_poll_timeout_atomic(),

resume, where interrupts are disabled.

21cded44e6 i3c: renesas: Restore STDBR and EXTBR registers on resume
The Renesas RZ/G3S supports a power saving state where power to the most
SoC componentes (including I3C) is lost.

The STDBR and EXTBR are configured in initialization phase though the
struct i3c_master_controller_ops::bus_init. Set them on resume function
as well to keep the same state of the controller after a suspend with
power loss and a similar initialization sequence as in bus_init.

5f1a76ecfe i3c: renesas: Check that the transfer is valid before accessing it
The Renesas I3C driver uses an asynchronous model to transfer data. It
prepares a struct renesas_i3c_xfer, enqueues it, and waits for completion.
The interrupt handler dequeues the transfer, updates/uses it, and signals
the waiting thread.

If the completion times out, the waiting thread dequeues the transfer and
free it. If an interrupt fires after that, the handler may access freed
memory, leading to crashes.

Check that the transfer is still valid before accessing it in the
interrupt handler. With it clear any status flags and disable all
the interrupts to avoid triggering the same interrupts again.

629a6ddd1d i3c: master: Add driver for AMD AXI I3C master controller
Add an I3C master driver and maintainers fragment for the AMD I3C bus
controller.

The driver currently supports the I3C bus operating in SDR mode,
with features including Dynamic Address Assignment, private data
transfers, and CCC transfers in both broadcast and direct modes. It
also supports operation in I2C mode.

The controller's data FIFOs are accessed big-endian; the driver performs
this conversion locally using ioread32be()/iowrite32be() with the
helpers, so it does not depend on any core FIFO-endianness helpers.

74be657d98 i3c: master: Fix device_register() error path
When device_register() fails in i3c_master_register_new_i3c_devs(),
put_device() is called to drop the reference taken by
device_register().  That drops the last reference, so the device's
release callback i3c_device_release() runs and frees the i3c_device.

Two problems follow from that:

i3c_device_release() does WARN_ON(i3cdev->desc), so it warns because
desc->dev->desc still points back at the descriptor.  Clear it before
calling put_device().

After put_device() frees the i3c_device, desc->dev is left pointing at
freed memory, so clear desc->dev as well.  That prevents, for example,
i3c_master_unregister_i3c_devs() seeing desc->dev as non-NULL and
dereferencing it.

e2bda39d7f i3c: master: svc: bound IBI payload to the requested max_payload_len
svc_i3c_master_handle_ibi() reads the IBI payload from the RX FIFO into
the IBI slot. The loop is bounded by the hardware FIFO size
(SVC_I3C_FIFO_SIZE), not by the slot size.

slot->data points into the IBI pool, which i3c_generic_ibi_alloc_pool()
sizes at max_payload_len per slot. svc_i3c_master_request_ibi() only
rejects a max_payload_len larger than SVC_I3C_FIFO_SIZE, so a driver can
request a smaller one. mctp-i3c requests 1. Each readsb() then copies the
controller RXCOUNT bytes (up to 31) with no check against the slot size.
A device that sends more bytes than the slot holds writes past
slot->data, an out-of-bounds write into the IBI pool.

Bound the loop by dev->ibi->max_payload_len and clamp each read to the
space left in the slot, the same way dw-i3c does. A device can still send
more than the requested payload. Flush the leftover bytes from the RX FIFO
so they do not leak into the next transfer.

adi_i3c_master_probe() requests the IRQ and unmasks REG_IRQ_PENDING_CMDR
before the controller's IBI state, transfer queue list and transfer

adi_i3c_master_irq() and take master->xferqueue.lock before the dynamic

This issue was found by our static analysis tool and then manually
reviewed against the current tree.

The grounded PoC kept the probe ordering and the IRQ path
adi_i3c_master_probe() -> adi_i3c_master_irq() -> xferqueue.lock, with a
pending CMDR interrupt arriving after REG_IRQ_PENDING_CMDR is unmasked.

d86d4f8cbb Input: gscps2 - advance receive buffer write index
Commit 44f9200699 ("Input: gscps2 - use guard notation when
acquiring spinlock") moved the receive loop into gscps2_read_data()
and gscps2_report_data().

While moving the code, it preserved the writes to
buffer[ps2port->append], but omitted the following producer index
update from the original loop:

	ps2port->append = (ps2port->append + 1) & BUFFER_SIZE;

As a result, append never advances. Since gscps2_report_data() only
reports bytes while act != append, the receive buffer always appears
empty and no keyboard or mouse data reaches the serio core.

Restore the omitted index update.

2d6d33e45d Input: rmi4 - tolerate short register descriptor structure
Some touchpads (e.g. ThinkPad T14 Gen 1) have buggy firmware that reports
a register descriptor structure size that is too small for the number of
registers it claims to have in the presence map. The remaining bytes in
the structure are 0, which with the new strict bounds checking causes the
parser to fail with -EIO, aborting the device probe.

Tolerate such short reads by dropping the remaining (unparseable or
0-size) registers from the list instead of failing the probe,
preventing the driver from trying to use them.

d85589879f Revert "Input: rmi4 - fix register descriptor address calculation"
The register descriptor presence register is a packet register, which
means its bytes share a single RMI address. It does not occupy
consecutive addresses, and the register structure that follows it
is located at the next RMI address (presence_address + 1), not
(presence_address + presence_size).

Revert the incorrect address calculation introduced in commit
a98518e724.

d1c3d45f87 ntb: amd: Use named initializer for pci_device_id::driver_data
The current list initialisation depends on the well hidden two zeros in
the PCI_VDEVICE macro. Instead use a named initialisation that is more
robust and easier to understand.

d876153680 NTB: epf: Avoid pci_iounmap() with offset when PEER_SPAD and CONFIG share BAR
When BAR_PEER_SPAD and BAR_CONFIG share one PCI BAR, the module teardown
path ends up calling pci_iounmap() on the same iomem with some offset,
which is unnecessary and triggers a kernel warning like the following:

  Trying to vunmap() nonexistent vm area (0000000069a5ffe8)
  WARNING: mm/vmalloc.c:3470 at vunmap+0x58/0x68, CPU#5: modprobe/2937

Fix it by unmapping only when PEER_SPAD and CONFIG use difference bars.

f0789fd342 spi: Fixes for v7.2
A fairly unremarkable collection of fixes that came in over the merge
 window, plus a new device ID for the DesignWare controller in the
 StarFive JHB100 SoC.  There's a couple of core fixes included, one
 avoiding freeing an empty resource in error handling cases and another
 which fixes a NULL dereference which could be triggered by using an
 abnormal device registration flow like driver_override.
