2020-07-02acpi_device: Replace polarity with active_low in acpi_gpio for GpioIoFurquan Shaikh
As per ACPI spec, GpioIo does not have any polarity associated with it. Linux kernel uses `active_low` argument within GPIO _DSD property to allow BIOS to indicate if the corresponding GPIO should be treated as active low. Thus, if GPIO has active high polarity or if it does not have any polarity associated with it, then the `active_low` argument is supposed to be set to 0. Having a `polarity` field in acpi_gpio seems confusing because GPIOs might not always have polarity associated with them. Example, in case of DMIC-select GPIO where 0 means select DMIC0 and 1 means select DMIC1, there is no polarity associated with the GPIO. Thus, it would be clearer for mainboard to use macros without having to specify a particular polarity. In order to enable mainboards to provide GPIO information without polarity for GpioIo usage, this change also adds `ACPI_GPIO_OUTPUT` and `ACPI_GPIO_INPUT` macros.

2020-06-28gpio_keys: Allow boards to configure different wakeup routesFurquan Shaikh
This change allows mainboard to configure different wakeup routes that can be used by a GPIO key: 1. SCI: This is selected when SCI route is used to wake the system. It results in _PRW property being exposed in ACPI tables. 2. GPIO IRQ: This is selected when GPIO controller wake is used to wake the system. It is typically used when the input signal is not dual routed and the GPIO controller block is not capable of applying filters for IRQ and wake separately. In this case, _PRW is not exposed in ACPI tables for the key device. 3. Disabled: No wakeup supported. Based on these wakeup routes, gpio_keys_add_child_node() is updated to expose _PRW and _DSD properties for wakeup appropriately. Additionally, the change updates mainboards that were already using gpio_keys to set wakeup_route attribute correctly and renames "wake" to "wake_gpe" to make the usage clear.

2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>
