2020-04-02Trim `.acpi_fill_ssdt_generator` and `.acpi_inject_dsdt_generator`Nico Huber
These two identifiers were always very confusing. We're not filling and injecting generators. We are filling SSDTs and injecting into the DSDT. So drop the `_generator` suffix. Hopefully, this also makes ACPI look a little less scary.

2020-03-25drivers/usb/acpi: Add needed #include fileTim Wawrzynczak
The chip.h for this driver was updated to add a reset GPIO, but did not add the required #include of <arch/acpi_device.h>. This likely still compiled because other chip.h files included before it may have included it themselves.

2019-10-22AUTHORS: Move src/drivers/[l*-v*] copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

2019-10-08device/root_device: Consolidate common _scan_bus() functionsNico Huber
scan_usb_bus() and root_dev_scan_bus() had the very same implementation. So rename the latter to scan_static_bus() and use that for both cases.

2018-12-04acpi_pld: Make it easier to define the ACPI USB device groupsDuncan Laurie
The Linux kernel can use the ACPI _PLD group information to determine peer ports. Currently to define the group information the devicetree must provide a complete _PLD structure. This change pulls the group information into a separate structure that can be defined in devicetree. This makes it easier to set for USB devices in devicetree that do not need a full custom PLD. This was tested on a sarien board with the USB devices defined by verifying that the USB 2/3 ports are correctly identified with their peer in sysfs.

2018-05-18drivers/usb/acpi: Add a driver for generating USB ACPIDuncan Laurie
Add a support for generating USB port descriptors for ACPI based on their definition by the board in devicetree.cb. This will generate a _UPC and _PLD for each port, using a generic _PLD by default. The _PLD can also be customized for more accurate descriptions if necessary. This sample devictree.cb shows a USB 2.0 type-A port behind a root hub connected to an xHCI controller: device pci 14.0 on chip drivers/usb/acpi register "desc" = ""Root Hub"" register "type" = "UPC_TYPE_HUB" device usb 0.0 on chip drivers/usb/acpi register "desc" = ""USB 2.0 Type-A"" register "type" = "UPC_TYPE_A" device usb 2.0 on end end end end end It will generate the following ACPI code in the SSDT: Scope (\_SB.PCI0.XHCI.RHUB.HS01) { Name (_DDN, "USB 2.0 Type-A") Name (_UPC, Package (0x04) { 0xFF, 0x00, Zero, Zero }) Name (_PLD, ToPLD ( PLD_Revision = 0x2, PLD_IgnoreColor = 0x1, PLD_Red = 0x0, PLD_Green = 0x0, PLD_Blue = 0x0, PLD_Width = 0x0, PLD_Height = 0x0, PLD_UserVisible = 0x1, PLD_Dock = 0x0, PLD_Lid = 0x0, PLD_Panel = "UNKNOWN", PLD_VerticalPosition = "CENTER", PLD_HorizontalPosition = "CENTER", PLD_Shape = "RECTANGLE", PLD_GroupOrientation = 0x0, PLD_GroupToken = 0x0, PLD_GroupPosition = 0x0, PLD_Bay = 0x0, PLD_Ejectable = 0x0, PLD_EjectRequired = 0x0, PLD_CabinetNumber = 0x0, PLD_CardCageNumber = 0x0, PLD_Reference = 0x0, PLD_Rotation = 0x0, PLD_Order = 0x0, PLD_VerticalOffset = 0x0, PLD_HorizontalOffset = 0x0) ) } Change-Id: I7024390e407fda4b195211bd4755bb5ca53b2b37 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/26173 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
