Merge tag 'drm-rust-next-2025-09-16' of https://gitlab.freedesktop.org/drm/rust/kernel into drm-next
DRM Rust changes for v6.18 Alloc - Add BorrowedPage type and AsPageIter trait - Implement Vmalloc::to_page() and VmallocPageIter - Implement AsPageIter for VBox and VVec DMA & Scatterlist - Add dma::DataDirection and type alias for dma_addr_t - Abstraction for struct scatterlist and struct sg_table DRM - In the DRM GEM module, simplify overall use of generics, add DriverFile type alias and drop Object::SIZE. Nova (Core) - Various register!() macro improvements (paving the way for lifting it to common driver infrastructure) - Minor VBios fixes and refactoring - Minor firmware request refactoring - Advance firmware boot stages; process Booter and patch its signature, process GSP and GSP bootloader - Switch development fimrware version to r570.144 - Add basic firmware bindings for r570.144 - Move GSP boot code to its own module - Clean up and take advantage of pin-init features to store most of the driver's private data within a single allocation - Update ARef import from sync::aref - Add website to MAINTAINERS entry Nova (DRM) - Update ARef import from sync::aref - Add website to MAINTAINERS entry Pin-Init - Merge pin-init PR from Benno - `#[pin_data]` now generates a `*Projection` struct similar to the `pin-project` crate. - Add initializer code blocks to `[try_][pin_]init!` macros: make initializer macros accept any number of `_: {/* arbitrary code */},` & make them run the code at that point. - Make the `[try_][pin_]init!` macros expose initialized fields via a `let` binding as `&mut T` or `Pin<&mut T>` for later fields. Rust - Various methods for AsBytes and FromBytes traits Tyr - Initial Rust driver skeleton for ARM Mali GPUs. - It can power up the GPU, query for GPU metatdata through MMIO and provide the metadata to userspace via DRM device IOCTL (struct drm_panthor_dev_query).
