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
