[PATCHv2 0/4] memory: fsl_ifc: Switch to modern devm and platform IRQ APIs

[Rosen Penev]

Convert the Freescale IFC controller driver from legacy OF-specific
APIs to modern platform-device and devm-based equivalents. This
eliminates manual resource tracking in error paths and remove(),
simplifying the driver and reducing LoC by ~40%.

Patch 1 replaces irq_of_parse_and_map() with platform_get_irq() /
platform_get_irq_optional() and fixes unconditional free_irq() calls
on the optional NAND IRQ.
Patch 2 replaces of_iomap() with devm_platform_ioremap_resource(),
dropping the manual iounmap in remove/error paths and fixing a
missing free_irq on the main IRQ request_irq failure.
Patch 3 switches from request_irq to devm_request_irq, removing the
error-path labels entirely and reducing remove() to just
of_platform_depopulate.
Patch 4 removes of_platform_default_populate.

Rosen Penev (4):
  memory: fsl_ifc: Fix optional NAND IRQ handling and migrate to
    platform IRQ API
  memory: fsl_ifc: Use devm_platform_ioremap_resource and fix error
    paths
  memory: fsl_ifc: Use devm_request_irq and simplify remove
  memory: fsl_ifc: drop simple-bus emulation
