# GPIO and I2C controller drivers
#
# These drivers match against both PCI and ACPI devices.
# ACPI devices are classified by _HID → PCI-equivalent class/subclass/vendor
# codes via redox-driver-acpi's classify_acpi_device().
#
# Match criteria use the standard [[driver.match]] format with class/subclass/vendor.
# The ACPI bus fills these fields from the _HID classification table.
