2019-03-28ec/google/wilco: Add ACPI _BIX method for batteryDuncan Laurie
I added a method to fill out the _BIX package structure but never hooked it up to the expected _BIX method that the OS uses. This change adds _BIX method and uses the existing method to fill it out. It also adds ^ before the _UID in _BIF to match _BIX as the _UID is one level above the method.

However, there is a chance that a new wrapper API will be addedl which check 'ret < 0' to catch errors, assuming other interfaces behave the same.

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.

2018-11-12ec/google/chromeec: Configure EC_SYNC_IRQ as level triggeredFurquan Shaikh
EC_SYNC_IRQ from EC to host is level-triggered in practice and configuring it as edge-triggered on the host results in host missing events if there are multiple events queued on the EC side. This is because Linux kernel driver reads one event per irq and the EC does not de-assert the interrupt line until all events are drained out. This results in event queue being filled up completely on the EC and the host failing to see any of those events. This change configures EC_SYNC_IRQ as level triggered to allow the host to read events from the the EC as long as the line is asserted.

2018-11-06chromeec: Disable battery remaining capacity workaroundDaisuke Nojiri
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.

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.

2018-08-23google/chromeec: Add support for "base attached switch" deviceDmitry Torokhov
On some detachables, the mere presence of attached base is not enough to determine whether the device is in tablet mode or not, so we introducing a new "switch" in EC, separate from "Tablet Mode" switch, to signal whether the base is attached or not. We also want the driver to be separate from cros_ec_keyb, so we create a new ACPI device, C(hrome)B(ase)A(ttached)S(witch), with HID GOOG000B, and guard it with EC_ENABLE_CBAS_DEVICE.
