In most scenarios this variant is actually unused (VCR is written in
SSDR mode), but we need to provide an octal variant. The address is 24
bits but is sent over 4 bytes MSB first. This means we need to shift the
register address by one extra byte for the address to be correct.
I didn't catch this initially because the volatile register region is
256 bytes wide, so the write-then-read procedure did work with the small
register addresses I was using at that time: 0 and 1.

Both W35N02JW and W35N04JW diverge from W35N01JW when it comes to the
"data read" operation in ODTR mode. In order to stuff more address
bits (up to 18), the second command byte is replaced by the most
significant address bits, keeping the number of address bytes to 2.

Some devices stuff address bits in the double byte opcode (in place of
the repeated byte) in order to be able to increase the size of the
devices, without adding extra address bytes.
Create a flag to identify those devices. When the flag is set, use the
"packed" variant for the read data operation.

Sashiko noticed an out-of-bounds read [1].
In spi_nor_params_show(), the snor_f_names array is passed to
spi_nor_print_flags() using sizeof(snor_f_names).
Since snor_f_names is an array of pointers, sizeof() returns the total
number of bytes occupied by the pointers
(element_count * sizeof(void *))
rather than the element count itself. On 64-bit systems, this makes the
passed length 8x larger than intended.
Inside spi_nor_print_flags(), the 'names_len' argument is used to
bounds-check the 'names' array access. An out-of-bounds read occurs
if a flag bit is set that exceeds the array's actual element count
but is within the inflated byte-size count.
Correct this by using ARRAY_SIZE() to pass the actual number of
string pointers in the array.

In scpsys_get_bus_protection_legacy(), of_find_node_with_property()
returns a device node with its reference count incremented. The function
then calls of_node_put(node) before checking whether
syscon_regmap_lookup_by_phandle() returns an error. If an error occurs,
dev_err_probe() dereferences the node pointer to print diagnostic
information, but the node memory may have already been freed due to the
earlier of_node_put(), leading to a use-after-free vulnerability.
Fix this by moving the of_node_put() call after the error check, ensuring
the node is still valid when accessed in the error path.

Commit cac173bea57d ("ACPI: processor: idle: Rework the handling of
acpi_processor_ffh_lpi_probe()") moved the acpi_processor_ffh_lpi_probe()
call from acpi_processor_setup_cpuidle_dev(), where its return value was
ignored, to acpi_processor_get_power_info(), where it is now treated as
a hard failure. As a result, platforms where psci_acpi_cpu_init_idle()
returned -ENODEV stopped registering any cpuidle states, forcing CPUs to
busy-poll when idle.
On NVIDIA Grace (aarch64) systems with PSCIv1.1, pr->power.count is 1
(only WFI, no deep PSCI states beyond it), so the previous
"count = pr->power.count - 1; if (count <= 0) return -ENODEV;" check
returned -ENODEV for all 72 CPUs and disabled cpuidle entirely.
The lpi_states count is already validated in acpi_processor_get_lpi_info(),
so the check here is redundant. Simplify the loop to iterate over
lpi_states[1..power.count). When only WFI is present, the loop body
simply does not execute and the function returns 0, which is the correct
outcome: there is nothing to validate for FFH and no error to report.

If a device is attached to a PM domain through genpd_dev_pm_attach_by_id(),
genpd calls pm_runtime_enable() for the corresponding virtual device that
it registers. While this avoids boilerplate code in drivers, there is no
corresponding call to pm_runtime_disable() in genpd_dev_pm_detach().
This means these virtual devices are typically detached from its genpd,
while runtime PM remains enabled for them, which is not how things are
designed to work. In worst cases it may lead to critical errors, like a
NULL pointer dereference bug in genpd_runtime_suspend(), which was recently
reported. For another case, we may end up keeping an unnecessary vote for a
performance state for the device.
To fix these problems, let's add this missing call to pm_runtime_disable()
in genpd_dev_pm_detach().

Fix kernel-doc issues in optee_private.h and optee_msg.h:
- Add missing documentation for struct members: optee_msg_param_value,
optee_msg_param, optee_msg_arg, optee, and optee_ffa;
- Ensure member descriptions follow the order of declaration;
- Use consistent formatting (lowercase descriptions and ':' after
member names);
- Adjust indentation for better alignment;
This resolves kernel-doc warnings such as missing member descriptions
and incorrect prototype documentation.
No functional changes.

The dma_sync_single_for_device() function expects a dma_addr_t, but
iommu_pages_flush_incoherent() was incorrectly passing a virtual
address.
Since iommu_pages_start_incoherent() enforces a 1:1 mapping between
DMA addresses and physical addresses (checked via WARN_ON), we can
convert the virtual address to a physical address before passing it to
the DMA API.
This also matches the behaviour of the other non-x86 in
iommu_pages_free_incoherent(), which uses virt_to_phys(virt);

The I2S MCLK outputs on RK3588 are gated by bits in the SYS_GRF
register SOC_CON6 (offset 0x318). These gates control whether the
internal CRU MCLK signals reach the external IO pins connected to
audio codecs.
The kernel should explicitly manage these gates so that audio
functionality does not depend on bootloader register state. This is
analogous to what was done for RK3576 SAI MCLK outputs [1].
Register the SYS_GRF as an auxiliary GRF with grf_type_sys using
rockchip_clk_add_grf(), and add GATE_GRF entries for all four I2S
MCLK output gates:
- I2S0_8CH_MCLKOUT_TO_IO (bit 0)
- I2S1_8CH_MCLKOUT_TO_IO (bit 1)
- I2S2_2CH_MCLKOUT_TO_IO (bit 2)
- I2S3_2CH_MCLKOUT_TO_IO (bit 7)
Board DTS files that need MCLK on an IO pin can reference these
clocks, e.g.:
clocks = <&cru I2S0_8CH_MCLKOUT_TO_IO>;
Tested on the Youyeetoo YY3588 (RK3588) with an ES8388 codec on I2S0.

Due to CVE-2023-20585, the PPR log buffer must use the maximum supported
size (512K) on Genoa (Family 0x19, model >= 0x10) systems when SNP is
enabled, to mitigate a potential security vulnerability. Note that Family
0x19 models below 0x10 (Milan) do not support PPR when SNP is enabled.
Hence the PPR log size increase is only applied for model >= 0x10.
All other systems continue to use the default PPR log buffer size (8K).
Apply the errata fix by making the following changes:
- Introduce global new variable (amd_iommu_pprlog_size) to have PPR log buffer
size. Adjust variable size for Genoa family.
- Extend 'amd_iommu_apply_erratum_snp()' to also set the PPR log buffer
size to maximum for Family 0x19 model >= 0x10 when SNP is enabled.
- Rename PPR_* macros to make it more readable.

Due to CVE-2023-20585, the Event log buffer must use the maximum supported

to mitigate a potential security vulnerability. All other systems continue to

Apply the errata fix by making the following changes:
* Introduce new global variable (amd_iommu_evtlog_size) to have event log
buffer size. Adjust variable size for family 0x19.
* Since 'iommu_snp_enable()' must be called after the core IOMMU subsystem
is initialized, it cannot be moved to the early init stage. The SNP errata
must also be applied after the 'iommu_snp_enable()' check. Therefore,
'alloc_event_buffer()' and 'iommu_enable_event_buffer()' are now called
in the IOMMU_ENABLED state, after the errata is applied.
* Adjust alloc_event_buffer() and iommu_enable_event_buffer() to handle
all IOMMU instances.
* Also rename EVT_* macros to make it more readable.

Remove the grf_type_sys exclusion from the auxiliary GRF table lookup
in rockchip_clk_register_branches(). Previously, branches with
grf_type_sys always used ctx->grf directly, bypassing the aux_grf_table.
This is a problem on SoCs like RK3588 where ctx->grf points to the
PHP_GRF (set via the CRU's rockchip,grf phandle), but GATE_GRF clock
entries need to access the SYS_GRF instead.
With this change, grf_type_sys branches first check the aux_grf_table,
and fall back to ctx->grf if no entry is found. This is backwards
compatible: on SoCs that do not register grf_type_sys in the
aux_grf_table, the behavior is unchanged.

Expose Cadence USBSSP through the same platform path as USBSS, trim
Kconfig and Makefile: one core loadable object plus separate glue .ko
files.
Single cdns.ko bundles core, DRD, the generic "cdns,usb3" platform
driver in cdns3-plat.c, optional host.o, and optional gadget objects.
Use CONFIG_USB_CDNS3_GADGET as a bool to compile gadget support into
that module. Remove duplicate MODULE_* declarations from cdns3-plat.c
now that it links into the same module.
Kconfig: the generic platform driver is selected via CONFIG_USB_CDNS3.
Move CONFIG_USB_CDNSP_PCI beside CONFIG_USB_CDNS3_PCI_WRAP under
"Platform glue driver support". SoC glue entries (TI, i.MX, StarFive)
depend only on CONFIG_USB_CDNS3.
Tighten CONFIG_USB_CDNS_SUPPORT dependencies so the umbrella follows
host or gadget when either is built as a module. Match host and gadget
bools to the cdns.ko tristate with USB=USB_CDNS3 and USB_GADGET=USB_CDNS3
instead of comparing against USB_CDNS_SUPPORT.
Link host.o when CONFIG_USB_CDNS3_HOST is enabled and use that symbol in
host-export.h, removing the redundant CONFIG_USB_CDNS_HOST indirection.
Export cdns_core_init_role and reorganize the function cdns_init, and
controller version could be gotten before the gadget init function is
decided per controller.
Keep host_init / gadget_init callbacks in struct cdns, so core.c does
not need direct linkage to host or gadget objects. Refactor cdnsp-pci.c
into a thin PCI-to-platform wrapper.
drivers/usb/Makefile: descend into drivers/usb/cdns3/ only when
CONFIG_USB_CDNS_SUPPORT is enabled.

The device controller may update vbus status via usb_udc_vbus_handler(),
which tries to connect the gadget even though gadget_bind_driver() has
already called usb_udc_connect_control_locked(). This causes pullup() to
be called twice. Avoid this by checking if gadget->connected is true.
This also set gadget->connected as false in usb_gadget_activate() if it
became connected while it was being deactivated. Otherwise,
usb_gadget_connect_locked will return early and pullup() won't be called.

The Cadence CDNSP controller optionally supports eUSB2 (embedded USB2)
port. While this port type operates logically like high-speed USB 2.0,
it utilizes a different physical layer signaling.
This patch:
- Extends the port detection logic to recognize the eUSB2 protocol.
- Tracks the eUSB2 port offset in the cdnsp_device structure.
- Ensures that eUSB2 ports are correctly handled during Link State
transitions, specifically forcing L0 when LPM is capable, similar

reduce code complexity and improve readability by removing unnecessary
abstraction.

The %pe format specifier resolves error pointers to their symbolic
representation. Previously %ld with PTR_ERR() was being used, %pe is a
better alternative.
Fixes the following coccinelle warnings reported by coccicheck:
WARNING: Consider using %pe to print PTR_ERR()
Testing: I do not own the hardware, therefore I could not perform
hardware testing. Compile tested only.

The dump_chip_info() function formats chip version information into a
local 128-byte buffer using the scnprintf(). This buffer was previously
passed to the DBG_871X macro.
Commit 968b15adb0ea ("staging: rtl8723bs: remove all DBG_871X logs")
removed the macro, leaving the buffer formatted but never used or output
anywhere.
dump_chip_info() is now useless, so remove it and its call from
ReadChipVersion8723B().

Move the ssid memcpy() inside the ie null-check to avoid calling it
with a NULL-derived pointer (p + 2) when the ie is missing.
While the kernel handles 0-length memcpy() safely as a no-op, keeping
the call outside the check is confusing and poor practice. This
change improves code readability.

The struct rtw_regulatory is never used in the rtl8723bs driver.
Functions taking it as a parameter are always passed NULL and
perform no logic with it. Remove the dead code and the struct.
