The Cortina CAxxxx GPIO driver maintains DM_GPIO support
across different CPU ISA in the CAxxxx Soc Family; Not just ARM.
Therefore, it is not desirable to split out and maintain separete
gpio header file for each CPU architecture.

Overwritting a discontiguous test file (file0007.raw) no longer causes
corruption to file0003.raw, which's data lies between the chunks of the
test file. The amount of data written to disk is still incorrect, what
causes damage to the file (file0005.raw), which's data lies next to the
test file. This will be fixed by the next patch.
Feel free to prepare a proper sandbox/py_test based tests based on the
provided test scripts.
Use the correct return value in function do_gpio() and update
commands documentation with the return values from command_ret_t enum.
CMD_RET_SUCCESS is returned on command success and CMD_RET_FAILURE is
returned on command failure.
The command was returning the pin value, which caused confusion when
debugging (#define DEBUG).

At present driver model supports the IRQ uclass but there is no way to
request a particular interrupt for a driver.
Add a mechanism, similar to clock and reset, to read the interrupts
required by a device from the device tree and to request those interrupts.
U-Boot itself does not have interrupt-driven handlers, so just provide a
means to read and clear an interrupt. This can be useful to handle
peripherals which must use an interrupt to determine when data is
available, for example.
Bring over the basic binding file as well, from Linux v5.4. Note that the
older binding is not supported in U-Boot; the newer 'special form' must be
used.
Add a simple test of the new functionality.

There can be different types of interrupt controllers in a system and some
drivers may need to distinguish between these. In general this can be
handled using the device tree by adding the interrupt information to
device nodes.
However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.
Add support for this in sandbox along with a test.

This config is not actually used here and in U-Boot it seems better to set
this using the device tree for each individual controller. The monolithic
config of the FSP-S is only necessary if the FSP is actually configuring
something, but here it is not.
The FSP-S does enable/disable the various I2C ports. It might be nice to
handle this using the okay/disabled property of each port, but that can be
considered later.

At present dm/device.h includes the linux-compatible features. This

One of these is malloc.h which we thus end up including in every file in

which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.
