185f812c41 doc: replace @return by Return:
Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

23dd0ea4c7 dm: acpi: Use correct GPIO polarity type in acpi_dp_add_gpio()
This function currently accepts the IRQ-polarity type. Fix it to use the
GPIO type instead.

0667900049 acpi: Support copying properties from device tree to ACPI
Some drivers in Linux support both device tree and ACPI. U-Boot itself
uses Linux device-tree bindings for its own configuration but does not use
ACPI.

It is convenient to copy these values over to the ACPI DP table for
passing to linux. Add some convenience functions to help with this.

2357234666 acpi: Support writing a GPIO
Allowing writing out a reference to a GPIO within the ACPI output. This
can be used by ACPI code to access a GPIO at runtime.

0e5a0a00d6 acpi: Support writing Device Properties objects via _DSD
More complex device properties can be provided to drivers via a
device-specific data (_DSD) object.

To create this we need to build it up in a separate data structure and
then generate the ACPI code, due to its recursive nature.

Add an implementation of this.
