2025-09-12watchdog: rzv2h: Improve error strings and add newlinesLad Prabhakar
Update rzv2h_wdt_probe() to provide clearer error strings when retrieving the pclk, oscclk, and reset controller, and append missing newline characters to dev_err_probe() and dev_warn() calls for proper log formatting.

2025-09-12watchdog: rzv2h: Add support for RZ/T2HLad Prabhakar
Add support for the RZ/T2H watchdog timer. The RZ/T2H requires control of the watchdog counter using the WDT Debug Control Register (WDTDCR), which allows explicitly stopping and starting the counter. This behavior differs from RZ/V2H, which doesn't have WDTDCR, so the driver is extended to handle this requirement. To support this, a new `wdtdcr` flag is introduced in the `rzv2h_of_data` structure. When set, the driver maps the WDTDCR register and uses it to control the watchdog counter in the start, stop, and restart callbacks. Additionally, the clock divisor and count source for RZ/T2H are defined to match its hardware configuration.

2025-09-12watchdog: rzv2h: Add support for configurable count clock sourceLad Prabhakar
Add support for selecting the count clock source used by the watchdog timer. The RZ/V2H(P) SoC uses the LOCO as the count source, whereas on RZ/T2H and RZ/N2H SoCs, the count source is the peripheral clock (PCLKL). Introduce a `count_source` field in the SoC-specific data structure and refactor the clock rate selection logic accordingly. This prepares the driver for supporting the RZ/T2H and RZ/N2H SoCs, which differ in their watchdog clocking architecture from RZ/V2H(P).

2025-09-12watchdog: rzv2h: Make "oscclk" and reset controller optionalLad Prabhakar
Update the rzv2h_wdt driver to make the "oscclk" clock and reset controller optional. Use devm_clk_get_optional_prepared() to obtain the "oscclk" clock, allowing the driver to work on platforms that do not provide this clock, such as the RZ/T2H SoC. Similarly, use devm_reset_control_get_optional_exclusive() to allow the driver to function on platforms that lack a reset controller. These changes are preparatory steps for supporting the RZ/T2H SoC, which does not provide an "oscclk" clock or a reset controller.

2025-09-12watchdog: rzv2h: Obtain clock-divider and timeout values from OF match dataLad Prabhakar
Update the rzv2h_wdt driver to fetch clock configuration and timeout parameters from device tree match data rather than relying on hardcoded constants. Introduce a new structure rzv2h_of_data that encapsulates minimum and maximum clock select values (cks_min and cks_max), clock divider (cks_div), timeout cycle count (timeout_cycles), and the timeout period select bits (tops). These values are provided through the OF match table and retrieved via of_device_get_match_data() during probe. This change allows dynamic configuration of the watchdog timer for different SoCs, such as the RZ/T2H, which require different settings.

As reported by Dan Carpenter, if the axes_enable field wasn't found, trying to find the axes themselves will result in a null pointer dereference. This could only occur with a broken PID descriptor, but it's worth protecting from.

2025-09-12HID: intel-ish-ipc: Remove redundant ready check after timeout functionZhang Lixu
timed_wait_for_timeout() internally checks for ish_is_input_ready() and ishtp_fw_is_ready() based on the provided parameters. If timed_wait_for_timeout() returns 0, it indicates the status is ready. In rare cases, another thread may send a message immediately after timed_wait_for_timeout() returns, causing a subsequent ish_is_input_ready() check to fail. Since the return value of timed_wait_for_timeout() is sufficient to determine readiness, the additional ready check is unnecessary and may introduce issues. This patch removes the redundant check and relies solely on the return value of timed_wait_for_timeout().

Since commit 6485543488a6 ("HID: cp2112: use new line value setter callbacks"), setting a GPIO value always fails with error -EBADE. That's because the returned value by the setter callbacks is the returned value by the hid_hw_raw_request() function which is the number of bytes sent on success or a negative value on error. The function gpiochip_set() returns -EBADE if the setter callbacks return a value > 0. Fix this by making the setter callbacks return 0 on success or a negative value on error. While at it, use the returned value by cp2112_gpio_set_unlocked() in the direction_output callback.

When a BPF gets loaded, it was previously not possible to bind a hid-generic device to hid-multitouch because the group was never updated. This change forces a rescan of the report descriptor after a bpf is loaded/unloaded so we set up the proper group. This was detected while Peter was trying to fix a Viewsonic device: the HID device sending multiotuch data through a proprietary collection was handled by hid-generic, and we don't have any way of attaching it to hid-multitouch because the pre-scanning wasn't able to see the Contact ID HID usage.

2025-09-12HID: lenovo: Use KEY_PERFORMANCE instead of ACPI's platform_profileJanne Grunau
Commit 84c9d2a968c82 ("HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd Fn keys") added a dependency on ACPI's platform_profile. This should not be done for generic USB devices as this prevents using the devices on non ACPI devices like Apple silicon Macs and other non-ACPI arm64 systems. An attempt to allow using platform_profile on non-ACPI systems was rejected in [1] and instead platform_profile was made to fail during init in commit dd133162c9cf ("ACPI: platform_profile: Avoid initializing on non-ACPI platforms"). So remove the broken dependency and instead let's user space handle this keycode by sending the new KEY_PERFORMANCE. Stable backport depends on commit 89c5214639294 ("Input: add keycode for performance mode key").

2025-09-12misc: fastrpc: Skip reference for DMA handlesLing Xu
If multiple dma handles are passed with same fd over a remote call the kernel driver takes a reference and expects that put for the map will be called as many times to free the map. But DSP only updates the fd one time in the fd list when the DSP refcount goes to zero and hence kernel make put call only once for the fd. This can cause SMMU fault issue as the same fd can be used in future for some other call.

2025-09-12staging: sm750fb: remove unnecessary volatile qualifiersYiming Qian
The use of 'volatile' for memory-mapped I/O pointers is discouraged in the Linux kernel as per Documentation/process/volatile-considered-harmful.rst. This patch removes the unnecessary 'volatile' qualifiers from the lynx_accel struct members, improving code quality and maintainability.

Some platforms (like lemans) feature one or more GPDSPs (General Purpose DSPs). Similar to other kinds of Hexagon DSPs, they provide a FastRPC implementation, allowing code execution in both signed and unsigned protection domains. Extend the checks to allow domain names starting with "gdsp" (possibly followed by an index).
