2025-09-15dpll: zl3073x: Refactor DPLL initializationIvan Vecera
Refactor DPLL initialization and move DPLL (de)registration, monitoring control, fetching device invariant parameters and phase offset measurement block setup to separate functions. Use these new functions during device probe and teardown functions and during changes to the clock_id devlink parameter. These functions will also be used in the next patch implementing devlink flash, where this functionality is likewise required.

2025-09-15dpll: zl3073x: Add firmware loading functionalityIvan Vecera
Add functionality for loading firmware files provided by the vendor to be flashed into the device's internal flash memory. The firmware consists of several components, such as the firmware executable itself, chip-specific customizations, and configuration files. The firmware file contains at least a flash utility, which is executed on the device side, and one or more flashable components. Each component has its own specific properties, such as the address where it should be loaded during flashing, one or more destination flash pages, and the flashing method that should be used.

2025-09-15dpll: zl3073x: Add low-level flash functionsIvan Vecera
To implement the devlink device flash functionality, the driver needs to access both the device memory and the internal flash memory. The flash memory is accessed using a device-specific program (called the flash utility). This flash utility must be downloaded by the driver into the device memory and then executed by the device CPU. Once running, the flash utility provides a flash API to access the flash memory itself. During this operation, the normal functionality provided by the standard firmware is not available. Therefore, the driver must ensure that DPLL callbacks and monitoring functions are not executed during the flash operation. Add all necessary functions for downloading the utility to device memory, entering and exiting flash mode, and performing flash operations.

2025-09-15dpll: zl3073x: Add functions to access hardware registersIvan Vecera
Besides the device host registers that are directly accessible, there are also hardware registers that can be accessed indirectly via specific host registers. Add register definitions for accessing hardware registers and provide helper functions for working with them. Additionally, extend the number of pages in the regmap configuration to 256, as the host registers used for accessing hardware registers are located on page 255.

Add a driver for the AMD Versal NET DDR memory controller which supports single bit error correction, double bit error detection and other system errors from various IP subsystems (e.g., RPU, NOCs, HNICX, PL). The driver listens for notifications from the NMC (Network management controller) using RPMsg (Remote Processor Messaging). The channel used for communicating to RPMsg is named "error_edac". Upon receipt of a notification, the driver sends a RAS event trace.

VirtIO transport initialization - set DRIVER_OK before SCMI probing to prevent potential stalls; while recent rework removes the practical risk, this ensures correctness (Junnan Wu). 4. Quirk handling - fix a critical bug by preventing writes to string constants, avoiding faults in read-only memory (Johan Hovold). 5. i.MX SCMI MISC protocol - extend support to discover board info, retrieve configuration and build data, and document the new MISC_BOARD_INFO command; all handled gracefully if unsupported (Peng Fan). 6.

2025-09-15firmware: qcom: scm: add support for object invocationAmirreza Zarrabi
Qualcomm TEE (QTEE) hosts Trusted Applications (TAs) and services in the secure world, accessed via objects. A QTEE client can invoke these objects to request services. Similarly, QTEE can request services from the nonsecure world using objects exported to the secure world. Add low-level primitives to facilitate the invocation of objects hosted in QTEE, as well as those hosted in the nonsecure world. If support for object invocation is available, the qcom_scm allocates a dedicated child platform device. The driver for this device communicates with QTEE using low-level primitives.

2025-09-15spi: amlogic: Fix error checking on regmap_write callColin Ian King
Currently a call to regmap_write is not being error checked because the return checke is being performed on the variable ret and this variable is not assigned the return value from the regmap_write call. Fix this by adding in the missing assignment.
