2022-04-14drivers/usb/acpi: acpi_power_res_params: Add use_gpio_for_statusTim Van Patten
Add the member `use_gpio_for_status` to the structure `drivers_usb_acpi_config`, so the `devicetree.cb` can specify it. This field is then used to initialize the corresponding field in the structure `acpi_power_res_params` in `usb_acpi_fill_ssdt_generator()`. The member `acpi_power_res_params::use_gpio_for_status()` is already being used by `acpi_device_add_power_res()` to determine which version of the `_STA()` method to output.

2020-11-09drivers/usb/acpi: Add support for privacy_gpioRicardo Ribalda
Some devices, such as cameras, can implement a physical switch to disable the input on demand. Think of it like the typical privacy sticker on the notebooks, but more elegant. In order to notify the system about the status this feature, a GPIO is typically used. The map between a GPIO and the feature is done via ACPI, the same way as the reset_gpio works. This patch implements an extra field for the described privacy gpio. This gpio does not require any extra handling from the power management.

2020-11-09driver/usb/acpi: Add power resources for devices on USB portsKarthikeyan Ramasubramanian
Allow a USB device to define PowerResource in its SSDT AML code. PowerResouce ACPI generation expects SoC to define the callbacks for generating AML code for GPIO manipulation. Device requiring PowerResource needs to define following parameters: * Reset GPIO - Optional, GPIO to put device into reset or take it out of reset. * Reset delay - Delay after reset GPIO is asserted (default 0). * Reset off delay - Delay after reset GPIO is de-asserted (default 0). * Enable GPIO - Optional, GPIO to enable device. * Enable delay - Delay after enable GPIO is asserted (default 0). * Enable off delay - Delay after enable GPIO is de-asserted (default 0). BUG=b:163100335 TEST=Ensure that the Power Resource ACPI object is added under the concerned USB device.

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>

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.

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>
