2020-07-18ec/google/chromeec: Fix oversights in ec_dptf_helpersTim Wawrzynczak
GTSH was 2 instead of 20 (so it's 2 degrees K hysteresis), and TSRD was accidentally defined to take 0 arguments, instead of 1.

ec_fill_dptf_helpers() is used to generate all of the "helper" methods that DPTF requires.

Testing of the Wilco EC has verified this behavior.

2020-04-22ec/google/chromeec: Fix acpi_name() for Chrome EC deviceFurquan Shaikh
In ACPI tables, Chrome EC device (CREC - HID GOOG0004) is a child of EC device (EC0 - HID PNP0C09). However, in coreboot device tree, there is no separate chip/device for EC0. Thus, acpi_name() needs to return EC0.CREC as the ACPI name for the Chrome EC device. By returning the ACPI name as EC0.CREC, all devices that live under Chrome EC device can simply call acpi_device_path()/acpi_device_scope() to emit the right path/scope. In the future, if we ever add a special chip driver for handling EC0 (HID PNP0C09), then the ACPI name for Chrome EC can be fixed to return CREC. BUG=b:154290952 TEST=Verified that acpi_device_path()/acpi_device_scope() return the correct name for Chrome EC device.

The message is “Method Argument is never used (Arg0)” on Method (TEVT, 1, NotSerialized), which indicates the TEVT method is empty. The solution is to only enable the TEVT code in mainboard or SoC when an EC is used that uses this event. The TEVT code in the EC is only enabled if the mainboard or SoC code implements TEVT. The TEVT method will be removed from the ASL code when the EC does not support TEVT. BUG=N/A TEST=Tested on facebook monolith.

Commit 77ad581ce [chromeec: PS2K node can't be under SIO node] moved the PS2K ACPI device from under the SIO device to under the LPCB, and while this fixed the keyboard under Windows for Skylake devices, it was insufficient for Baytrail and Braswell devices (and likely Apollo Lake/Gemini Lake too). Moving the PS2K device under PCI0 allows the PS2K to be functional under Windows for all Chrome-EC platforms.

2019-05-20ec/google/wilco: Add support for KB_ERR_CODE to Wilco ECKeith Short
Adds support for the KB_ERR_CODE command on the Wilco EC. This command is used to drive diagnostic LEDs on the platform after a failed boot.
