2019-08-23google/chromeos: Support AP watchdog flag from Chrome ECYou-Cheng Syu
After ChromiumOS CL:1293132 and CL:1295890, Chrome EC can store the flag telling if the last reboot was triggered by AP watchdog for some boards (e.g., Kukui). This CL adds a new function google_chromeec_get_ap_watchdog_flag(), which reads the AP watchdog flag from Chrome EC, and updates the tables of reset causes and reset flags. A new Kconfig option CHROMEOS_USE_EC_WATCHDOG_FLAG is added for elog_handle_watchdog_tombstone() to determine if watchdog reset was triggered by the AP watchdog flag from EC instead of the tombstone in AP.

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.

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.

If remaining charge is more than x% of the full capacity, the remaining charge is raised to the full capacity before it's reported to the rest of the system. Some batteries don't update full capacity timely or don't update it at all. On such systems, compensation is required to guarantee the remaining charge will be equal to the full capacity eventually. On some systems, Rohm charger generates audio noise when the battery is fully charged and AC is plugged. A workaround is to do charge- discharge cycles between 93 and 100%. On such systems, compensation was also applied to mask this cycle from users. This used to be done in ACPI, thus, all software components except EC was able to see the compensated charge. This patch is part of the effort of moving the logic to EC. With this and the EC changes, EC can see what the rest of the system sees, thus, can control LEDs synchronously (to the display percentage). Another rationale of this move is EC can perform more granular and precise compensation than ACPI since it has more knowledge about the battery and the charger.

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.

2018-10-04ec/google/chromeec: Define a sync IRQ if neededDuncan Laurie
Some boards are adding a second pin used for synchronization between the EC and AP. This is a direct connection between the EC and the SOC that is intended to provide a lower latency interrupt signal for sensors on the EC. Currently the runtime EC interrupts assert an SCI before eventually resulting in a Notify() on the MKBP device that the sensor driver users. These extra layers add processing time and require additional EC communication to determine the event source. This interface was tested on a reworked Nocturne board with modified EC and a modified kernel driver to ensure that the interrupt asserts as expected and can be used by the kernel driver.
