The iris VPU hardware uses multiple IOMMU context banks (CBs) to partition its virtual address space. Each CB provides an independent IOVA range, which allows the driver to support a larger number of concurrent video sessions without exhausting a single shared IOVA space. Introduce iris_create_cb_dev() to allocate and register each CB device, and add an init_cb_devs() hook to iris_platform_data so that per-SoC platform files can create the appropriate set of CB devices with their corresponding stream ID arrays.

Depending on the buffer type (input, output and internal), associated context bank is selected, if available. Fallback to parent device for backward compatibility.

The H265 decoder line buffer size calculation for iris4 (VPU4) was previously reusing the iris3 formula. While this works for most resolutions, certain configurations require a larger buffer size on iris4, causing firmware errors during decode. This resolves firmware failures seen with specific test vectors on kaanapali (iris4), and fixes the following failing fluster tests - PICSIZE_C_Bossen_1 - WPP_E_ericsson_MAIN_2 Co-developed-by: Vishnu Reddy <busanna.reddy@oss.qualcomm.com> Signed-off-by: Vishnu Reddy <busanna.reddy@oss.qualcomm.com> Signed-off-by: Vikash Garodia <vikash.garodia@oss.qualcomm.com>
…source files Platform-specific data arrays and structs were defined as 'static' in header files. When a header is included in more than one place, each gets its own private copy of the data. Move all such definitions into dedicated per-platform .c files and replace the in-header definitions with extern declarations.

Switch the iris video codec node in sm8550 (kailua) and sa8775p (lemans) DTS from the legacy 'iommus' property to 'iommu-map', assigning named function IDs (IRIS_NON_PIXEL_VCODEC and IRIS_PIXEL) to each SMMU stream mapping. This allows the driver to look up and attach the correct IOMMU domain per context bank instead of sharing a single domain. Add a new dt-bindings header include/dt-bindings/media/qcom,sm8550-iris.h that defines the two function identifiers so they can be shared between device-trees and the driver without hard-coded magic numbers. Wire up sm8550_init_cb_devs() in iris_platform_gen2.c to register the two child context-bank platform devices (iris_non_pixel and iris_pixel) using iris_create_cb_dev(), and hook it into the sm8550_data platform data via the new .init_cb_devs callback.

This series adds context bank support to the Qualcomm iris video codec
driver by migrating from the legacy 'iommus' DT property to 'iommu-map',
enabling per-context-bank IOMMU domain management.
