Hi SoC Team,

Please merge the Apple SoC NVMe driver and its dependencies for 5.19.
As discussed on the nvme mailing list [1] it's easiest if we take it
entirely through the SoC tree since there's a chance that we will have
more drivers depending on rtkit for 5.19.

Thanks

Sven

  nvme-apple: Add initial Apple SoC NVMe driver (2022-05-02 17:24:45 +0200)

----------------------------------------------------------------
Apple SoC NVMe driver and dependencies:

  - RTKit IPC library required to boot and communicate with
    co-processors embedded inside Apple SoCs
  - SART DMA address filter required to allow some DMA transactions for
    the NVMe co-processor
  - NVMe platform driver

The following minor changes since v3 on the mailing list have been
folded in:

  - sart: %llx -> %pa for a phys_addr_t
  - rtkit:/sart: Drop IS_ENABLED inside headers
  - rtkit: Use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL
  - nvme: Set NVME_REQ_CANCELLED in the timeout handler
  - nvme: Use DEFINE_SIMPLE_DEV_PM_OPS instead of #ifdef CONFIG_PM_SLEEP
