Merge branch 'pci/endpoint'

- Free all previously requested IRQs in epf_ntb_db_bar_init_msi_doorbell()
  error path (Koichiro Den)

- Free doorbell IRQ in pci-epf-test only if it has actually been requested
  (Koichiro Den)

- Discard pointer to doorbell message array after freeing it in
  pci_epf_alloc_doorbell() error path (Koichiro Den)

- Advertise dynamic inbound mapping support in pci-epf-test and update host
  pci_endpoint_test to skip doorbell testing if not advertised by endpoint
  (Koichiro Den)

- Constify configfs item and group operations (Christophe JAILLET)

- Use array_index_nospec() on configfs MW show/store attributes (Koichiro
  Den)

- Return -ERANGE (not -EINVAL) for configfs out-of-range MW index (Koichiro
  Den)

- Return 0, not remaining timeout, when MHI eDMA ops complete so
  mhi_ep_ring_add_element() doesn't interpret non-zero as failure (Daniel
  Hodges)

- Remove vntb and ntb duplicate resource teardown that leads to oops when
  .allow_link() fails or .drop_link() is called (Koichiro Den)

- Disable vntb delayed work before clearing BAR mappings and doorbells to
  avoid oops caused by doing the work after resources have been torn down
  (Koichiro Den)

- Fix pci_epf_add_vepf() kernel-doc typo (Alok Tiwari)

- Propagate pci_epf_create() errors to pci_epf_make() callers (Alok Tiwari)

- Remove redundant BAR_RESERVED annotation for the high order part of a
  64-bit BAR (Niklas Cassel)

- Add a way to describe reserved subregions within BARs, e.g.,
  platform-owned fixed register windows, and use it for the RK3588 BAR4 DMA
  ctrl window (Koichiro Den)

- Add BAR_DISABLED for BARs that will never be available to an EPF driver,
  and change some BAR_RESERVED annotations to BAR_DISABLED (Niklas Cassel)

- Disable BARs in common code instead of in each glue driver (Niklas
  Cassel)

- Advertise reserved BARs in Capabilities so host-side drivers can skip
  them (Niklas Cassel)

- Skip reserved BARs in selftests (Niklas Cassel)

- Improve error messages and include device name when available (Manivannan
  Sadhasivam)

- Add NTB .get_dma_dev() callback for cases where DMA API requires a
  different device, e.g., vNTB devices (Koichiro Den)

- Return -EINVAL, not -ENOSPC, if endpoint test determines the subrange
  size is too small (Koichiro Den)

- Add reserved region types for MSI-X Table and PBA so Endpoint controllers
  can them as describe hardware-owned regions in a BAR_RESERVED BAR
  (Manikanta Maddireddy)

- Make Tegra194/234 BAR0 programmable and remove 1MB size limit (Manikanta
  Maddireddy)

- Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED
  (Manikanta Maddireddy)

- Add Tegra194 and Tegra234 device table entries to pci_endpoint_test
  (Manikanta Maddireddy)

- Skip the BAR subrange selftest if there are not enough inbound window
  resources to run the test (Christian Bruel)
