[PATCHv2 0/8] ata: sata_dwc_460ex: cleanups and interrupt ordering fix

[Rosen Penev <rosenp@gmail.com>]

This series modernizes the sata_dwc_460ex driver by replacing legacy OF
APIs with their modern device-property and platform-device counterparts,
converting old DMA resource teardown to devm-managed cleanup, fixing a
latent interrupt-ordering bug, and dropping a redundant stack copy of
port_info.

Patch 4 fixes a real issue: sata_dwc_enable_interrupts() was called
before the IRQ handler was registered, so a probe failure or an
asserted interrupt could trigger an unhandled irq storm.

v2: sashiko fixes.

Rosen Penev (8):
  ata: sata_dwc_460ex: use device_property_present()
  ata: sata_dwc_460ex: use platform_get_irq()
  ata: sata_dwc_460ex: enable SATA interrupts only after IRQ handler is
    registered
  ata: sata_dwc_460ex: drop redundant struct copy of port_info
  ata: sata_dwc_460ex: fix data race on hsdev->sactive_issued in
    interrupt handler
  ata: sata_dwc_460ex: disable SATA interrupts on device removal
  ata: sata_dwc_460ex: fix PHY lifecycle ordering on device removal
  ata: sata_dwc_460ex: use devm for old DMA resource lifetime management
