The GG.0 and GG.1 GPIOs serve as CLKREQ and RST pins, respectively, for
PCIe controller 5 on Tegra194. When this controller is configured in
endpoint mode, these pins need to be used as GPIOs by the PCIe endpoint
driver. Typically the mode programming of these pins (GPIO vs. SFIO) is
performed by early boot firmware to ensure that the configuration is
consistent.
However, the GG.0 and GG.1 pins are part of a special power partition
that is not enabled during early boot, and hence the early boot firmware
cannot program these pins to be GPIOs (they are SFIO by default). Adding
them as pin ranges for the pin controller allows the pin controller to
be involved when these pins are requested as GPIOs and allows the proper
programming to take place.

Wake gpiochip_generic_request() call into the pinctrl helpers only if a
GPIO controller had any pin-ranges assigned to it. This allows a driver
to unconditionally use this helper if it supports multiple devices of
which only a subset have pin-ranges assigned to them.

We don't currently support IOMMUs with a page granule larger than the
system page size. The IOVA allocator has a BUG_ON() in this case, and
VFIO has a WARN_ON().
Removing these obstacles ranges doesn't seem possible without major
changes to the DMA API and VFIO. Some callers of iommu_map(), for
example, want to map multiple page-aligned regions adjacent to each
others for scatter-gather purposes. Even in simple DMA API uses, a call
to dma_map_page() would let the endpoint access neighbouring memory. And
VFIO users cannot ensure that their virtual address buffer is physically
contiguous at the IOMMU granule.
Rather than triggering the IOVA BUG_ON() on mismatched page sizes, abort
the vdomain finalise() with an error message. We could simply abort the
viommu probe(), but an upcoming extension to virtio-iommu will allow
setting different page masks for each endpoint.

Calling viommu_domain_free() on a domain that hasn't been finalised (not
attached to any device, for example) can currently cause an Oops,
because we attempt to call ida_free() on ID 0, which may either be
unallocated or used by another domain.
Only initialise the vdomain->viommu pointer, which denotes a finalised
domain, at the end of a successful viommu_domain_finalise().
