The main purpose of this binding is to communicate Xen specific
information using generic IOMMU device tree bindings (which is
a good fit here) rather than introducing a custom property.
Introduce Xen specific IOMMU for the virtualized device (e.g. virtio)
to be used by Xen grant DMA-mapping layer in the subsequent commit.
The reference to Xen specific IOMMU node using "iommus" property
indicates that Xen grant mappings need to be enabled for the device,
and it specifies the ID of the domain where the corresponding backend
resides. The domid (domain ID) is used as an argument to the Xen grant
mapping APIs.
This is needed for the option to restrict memory access using Xen grant
mappings to work which primary goal is to enable using virtio devices
in Xen guests.

The depth of the transmit FIFO for the Cadence SPI controller is currently
hardcoded to 128. But the depth is a synthesis configuration parameter of
the core and can vary between different SoCs.
If the configured FIFO size is less than 128 the driver will busy loop in
the cdns_spi_fill_tx_fifo() function waiting for FIFO space to become
available.
Depending on the length and speed of the transfer it can spin for a
significant amount of time. The cdns_spi_fill_tx_fifo() function is called
from the drivers interrupt handler, so it can leave interrupts disabled for
a prolonged amount of time.
In addition the read FIFO will also overflow and data will be discarded.
To avoid this detect the actual size of the FIFO and use that rather than
the hardcoded value.
To detect the FIFO size the FIFO threshold register is used. The register
is sized so that it can hold FIFO size - 1 as its maximum value. Bits that
are not needed to hold the threshold value will always read 0. By writing
0xffff to the register and then reading back the value in the register we
get the FIFO size.

As part of unprepare_transfer_hardware, SPI controller will be disabled
which will indirectly deassert the CS line. This will create a problem
in some of the devices where message will be transferred with
cs_change flag set(CS should not be deasserted).
As per SPI controller implementation, if SPI controller is disabled then
all output enables are inactive and all pins are set to input mode which
means CS will go to default state high(deassert). This leads to an issue
when core explicitly ask not to deassert the CS (cs_change = 1). This
patch fix the above issue by checking the Slave select status bits from
configuration register before disabling the SPI.
