[PATCH v2 0/6] dma-buf: heaps: add coherent reserved-memory heap

by Albert Esteve

This patch introduces a new heap driver to expose DT non‑reusable "shared-dma-pool" coherent regions as dma-buf heaps, so userspace can allocate buffers from each reserved, named region. Because these regions are device‑dependent, each heap instance binds a heap device to its reserved‑mem region via a newly introduced helper function -namely, of_reserved_mem_device_init_with_mem()- so coherent allocations use the correct dev->dma_mem. Charging to cgroups for these buffers is intentionally left out to keep review focused on the new heap; I plan to follow up based on Eric’s [1] and Maxime’s [2] work on dmem charging from userspace. This series also makes the new heap driver modular, in line with the CMA heap change in [3].
