Pull GPIO fixes from Linus Walleij:
 "A last set of small fixes for GPIO, this cycle was quite busy.

   - Fix debounce delays on the MAX77620 GPIO expander

   - Use the correct unit for debounce times on the BD70528 GPIO expander

   - Get proper deps for parallel builds of the GPIO tools

   - Add a specific ACPI quirk for the Terra Pad 1061"

* tag 'gpio-v5.4-5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  gpiolib: acpi: Add Terra Pad 1061 to the run_edge_events_on_boot_blacklist
  tools: gpio: Correctly add make dependencies for gpio_utils
  gpio: bd70528: Use correct unit for debounce times
  gpio: max77620: Fixup debounce delays
