2025-05-21misc: microchip: pci1xxxx: Add GPIO Wakeup SupportRengarajan S
The patch adds PIO asynchronous wakeup support while PIO PCIe Endpoint function is in D3 state. When such a wakeup event occurs, the PIO asserts a PIO_WAKE signal, which in turn triggers PCIe Wake signaling. This wake request should trigger the PCIe Host to take the PIO PCIe Endpoint function into the D0 device state. The device supports up to 96 PIOs distributed across three GPIO banks. During suspend and resume, the driver checks the status of each GPIO bank to determine if any GPIOs with wake masking enabled have triggered an event. Upon resume, PIOxx_STATUS register must be cleared by software explicitly to enable the detection of the next transition.

2025-05-21misc: microchip: pci1xxxx: Add PCIe Hot reset disable support for Rev C0 and ↵Rengarajan S
later devices Systems that issue PCIe hot reset requests during a suspend/resume cycle cause PCI1XXXX device revisions prior to C0 to get its GPIO configuration registers reset to hardware default values. This results in device inaccessibility and GPIO read/write failure. Starting with Revision C0, support was added in the device hardware (via the Hot Reset Disable Bit) to allow resetting only the PCIe interface and its associated logic, but preserving the GPIO configurations during a hot reset. This patch enables the hot reset disable feature during suspend/ resume for C0 and later revisions of the device. mchp_pci1xxxx_gpio is an auxiliary child of mchp_pci1xxxx_gp and does not have access to system register address space for reading the device revision. Hence, the device revision is retrieved directly from PCIe config space.

2025-05-21binder: Create safe versions of binder log filesTiffany Y. Yang
Binder defines several seq_files that can be accessed via debugfs or binderfs. Some of these files (e.g., 'state' and 'transactions') contain more granular information about binder's internal state that is helpful for debugging, but they also leak userspace address data through user-defined 'cookie' or 'ptr' values. Consequently, access to these files must be heavily restricted. Add two new files, 'state_hashed' and 'transactions_hashed', that reproduce the information in the original files but use the kernel's raw pointer obfuscation to hash any potential user addresses. This approach allows systems to grant broader access to the new files without having to change the security policy around the existing ones. In practice, userspace populates these fields with user addresses, but within the driver, these values only serve as unique identifiers for their associated binder objects. Consequently, binder logs can obfuscate these values and still retain meaning. While this strategy prevents leaking information about the userspace memory layout in the existing log files, it also decouples log messages about binder objects from their user-defined identifiers.

2025-05-21binder: Refactor binder_node print synchronizationTiffany Y. Yang
The binder driver outputs information about each dead binder node by iterating over the dead nodes list, and it prints the state of each live node in the system by traversing each binder_proc's proc->nodes tree. Both cases require similar logic to maintain the global lock ordering while accessing each node. Create a helper function to synchronize around printing binder nodes in a list. Opportunistically make minor cosmetic changes to binder print functions. Acked-by: Carlos Llamas <cmllamas@google.com> Signed-off-by: "Tiffany Y.

2025-05-21can: dev: add struct data_bittiming_params to group FD parametersVincent Mailhol
This is a preparation patch for the introduction of CAN XL. CAN FD and CAN XL uses similar bittiming parameters. Add one level of nesting for all the CAN FD parameters. Typically: priv->can.data_bittiming; becomes: priv->can.fd.data_bittiming; This way, the CAN XL equivalent (to be introduced later) would be: priv->can.xl.data_bittiming; Add the new struct data_bittiming_params which contains all the data bittiming parameters, including the TDC and the callback functions.

2025-05-21nvmem: Remove unused nvmem cell table supportGeert Uytterhoeven
Board files are deprecated by DT, and the last user of nvmem_add_cell_table() was removed by commit 2af4fcc0d3574482 ("ARM: davinci: remove unused board support") in v6.3. Hence remove all support for nvmem cell tables, and update the documentation. Device drivers can still register a single cell using nvmem_add_one_cell() (which was not documented before).

Commit 29be47fcd6a0 ("nvmem: zynqmp_nvmem: zynqmp_nvmem_probe cleanup") changed the driver to expect the device pointer to be passed as the "context", but in nvmem the context parameter comes from nvmem_config.priv which is never set - Leading to null pointer exceptions when the device is accessed.

2025-05-21w1: Avoid -Wflex-array-member-not-at-end warningsGustavo A. R. Silva
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. Use the `DEFINE_RAW_FLEX()` helper for on-stack definitions of a flexible structure where the size of the flexible-array member is known at compile-time, and refactor the rest of the code, accordingly. So, with these changes, fix the following warnings: drivers/w1/w1_netlink.c:198:31: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/w1/w1_netlink.c:219:31: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Reviewed-by: Kees Cook <kees@kernel.org> Signed-off-by: "Gustavo A.
