Setting .n_voltages = 1 and .fixed_uV is enough for fixed regulator,
remove the redundant .min_uV and .list_voltage settings.

When a P2PDMA transfer is rejected due to ACS being set, we
can also check the white list and allow the transactions.
Do this by pushing the whitelist check into the
upstream_bridge_distance() function.

As discussed on the list previously, in order to fully support the
whitelist Christian added with the IOMMU, we must ensure that we
map any buffer going through the IOMMU with an aprropriate dma_map
call. This patchset accomplishes this by cleaning up the output of
upstream_bridge_distance() to
The result of upstream_bridge_distance() will be needed every time
we map the dma address so cache it in an xarray stored in the
provider's p2pdma struct.

Add pci_p2pdma_unmap_sg() to the two places that call

Intel devices do not have good support for P2P requests that span
different host bridges as the transactions will cross the QPI/UPI bus
and this does not perform well.
Therefore, enable support for these devices only if the host bridges

Push both PCI devices into the whitelist checking function seeing
some hardware will require us ensuring they are on the same host
bridge.
At the same time we rename root_complex_whitelist() to
host_bridge_whitelist() to match the terminology used in the code.

Add constant flags to indicate two devices are not supported or whether
the data path goes through the host bridge instead of using the negative
values -1 and -2.
This helps annotate the code better, but the main reason is so we
can cache the result in an xarray which does not allow us to store

This is to match the dma_map_sg() API which this function will have
to call in an future patch.

no attributes just like the dma_map_sg() function.

Any requests that traverse the host bridge will need to be mapped into
the IOMMU, so call dma_map_sg() inside pci_p2pdma_map_sg() when
appropriate.
Similarly, call dma_unmap_sg() inside pci_p2pdma_unmap_sg().

The LED behavior of some Ethernet PHYs is configurable. Add an
optional 'leds' subnode with a child node for each LED to be
configured. The binding aims to be compatible with the common
LED binding (see devicetree/bindings/leds/common.txt).
