2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2019-06-07ec/google/wilco: Add UCSI supportDuncan Laurie
This change adds support for the UCSI specification in order to provide information about the Type-C port and an interface to perform power and data role swap. This change is split across the DSDT and SSDT, with the shared memory and operation region declared in the SSDT after being allocated in CBMEM. The OS will fill in the registers in the system memory region and then call the _DSM method wtih a read or write argument. The DSM method will copy the required registers to/from the system memory and the EC and perform the write or read action. Responses from the EC will generate a new SCI with event code 0x79 which will notify this UCSI ACPI device and the OS driver will take action to read status from the EC.

2019-02-05ec/google/wilco: Add virtual button supportDuncan Laurie
Add an ACPI device that is compatible with the Intel Virtual Button kernel driver for reporting tablet mode state and various virtual button events that may come from the EC. This driver is used in Windows and in the Linux kernel at drivers/platform/x86/intel-vbtn.c Because of a check in the kernel driver it expects the board to define the SMBIOS enclosure type as convertible for the check at driver load time for tablet/laptop and dock/undock to work. The virtual tablet mode button will proxy the tablet mode state sent from the Sensor Hub to a SW_TABLET_MODE event in the kernel. The virtual power button is used during S0ix for the EC to wake the system with an SCI. There are separate press and release events which are sent for completeness, although the kernel driver will ignore the release event. BUG=b:73137291 TEST=Test that the power button can wake the system from S0ix. Also verify that the device is reported as laptop mode at boot.

2018-12-04ec/google/wilco/acpi: Add DPTF supportDuncan Laurie
Add the support needed for DPTF. This includes the methods to write trip point values, read temperatures, and handle events. This was tested on a sarien board by inspecting AML debug output with the kernel while monitoring temperatures and trip points in sysfs and controlling temperatures with a fan to ensure that when a trip point is crossed an SCI is generated and the event is handled properly.

2018-12-04ec/google/wilco: Fix extended event handlingDuncan Laurie
Extended events will be handled by the OS kernel driver, but that driver needs a method exposed by ACPI to read the event data from the EC and into a buffer. Tested by generating a hotkey event and reading the buffer from the Linux kernel driver with acpi_evaluate_object().

2018-10-31ec/google/wilco: Add ACPI EC infrastructureDuncan Laurie
Add the base ACPI support for the Wilco embedded controller, using ASL 2.0 syntax throughout. This includes the EC device and its resources, as well as the layout for the EC RAM and the functions needed to read and write to the EC RAM. The EC RAM address space is typically read/write, and so the ACPI EC device expects that a defined Field can be read and/or written. With this EC the read and write address spaces are different. For example, a read from address zero will return data that is unrelated to what a write to address zero expects. This makes using a typical OperationRegion to describe the EC RAM address space somewhat impracticle, since field definitions would overlap. Instead, methods are provided for reading and writing to an EC RAM offset, and the EC RAM layout is defined as a Package that describes offset+mask for read or write fields within the EC RAM.
