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.

2020-07-01acpi: Avoid freeing a device twiceSimon Glass
The current implementation of acpi_dp_write() frees the node after it has written it. If the structure contains a ACPI_DP_TYPE_CHILD then a recursive call to acpi_dp_write() frees the child and then frees it again when returning from the call. This results in a double free. Split the implementation into two steps, one that ones and one that frees. This is easier to understand and fixes the bug. Note: This likely has no effect in coreboot since it doesn't seem to have a proper free() implementation. But it might gain one one day.

2020-06-04acpi: Accomodate non-standard UUIDs in device propertiesDuncan Laurie
There have been changes to the way device properties are supported in Linux[1] and Windows[2] which add flexibilty: - non-standard UUIDs can be used instead of only ACPI_DP_UUID - support for multiple different packages within the _DSD that associate different properties with unique UUIDs. To handle this I extracted the part that does the write of UUID and properties to a separate function and defined a new PACKAGE type which has the custom UUID as a name and can be used the same way that child properties are today. For example a PCIe root port for a USB4 port has a standard property indicating the USB4 reference, and then two custom properties which are defined for different attributes. Example code: /* Create property table */ acpi_dp *dsd = acpi_dp_new_table("_DSD"); acpi_dp_add_reference(dsd, "usb4-port", usb4_path); /* Add package for hotplug */ acpi_dp *pkg = acpi_dp_new_table("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"); acpi_dp_add_integer(pkg, "HotPlugSupportInD3", 1); acpi_dp_add_package(dsd, pkg); /* Add package for external port info */ pkg = acpi_dp_new_table("efcc06cc-73ac-4bc3-bff0-76143807c389"); acpi_dp_add_integer(pkg, "ExternalFacingPort", 1); acpi_dp_add_package(dsd, pkg); /* Write all properties */ acpi_dp_write(dsd); Resulting ACPI: Scope (\_SB.PCI0.TRP0) { Name (_DSD, Package () { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") Package () { Package () { "usb4-port", \_SB.PCI0.TDM0.RHUB.PRTA } }, ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"), Package () { Package () { "HotPlugSupportInD3", One } }, ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"), Package () { Package () { "ExternalFacingPort", One }, } }) } [1] https://patchwork.kernel.org/patch/10599675/ [2] https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports Change-Id: I75f47825bf4ffc5e9e92af2c45790d1b5945576e Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/42047 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
