[PATCHv2 0/4] dma: fsl_raid: fix sparse warnings and simplify probing

[Rosen Penev]

This series cleans up the fsl_raid driver to address issues reported by
sparse and to simplify its MMIO handling.

Patch 1 fixes the endianness of in-memory descriptor stores. The
descriptor structs are handed to the device as big-endian, but the driver
stored CPU-endian values directly, which is both incorrect and flagged by
sparse as a base-type mismatch. The stores are wrapped in cpu_to_be32()
and the final-frame bit is now passed as an argument rather than
read-modify-written.

Patch 2 keeps the MMIO bases (re_regs and jrregs) as void __iomem *
instead of typed register struct pointers, eliminating "different address
spaces" sparse warnings on every register access. Each accessor derives a
local __iomem-qualified typed pointer.

Patch 3 replaces the open-coded platform_get_resource() +
devm_ioremap() sequence with devm_platform_ioremap_resource().

v2: split up first patch and simplify __iomem patch.

Rosen Penev (4):
  dma: fsl_raid: convert descriptor stores to big-endian
  dma: fsl_raid: set final bit via fill_cfd_frame() argument
  dma: fsl_raid: keep MMIO bases as void __iomem and cast at access
  dma: fsl_raid: use devm_platform_ioremap_resource
