2019-06-13ec/google/wilco: Read back from EC RAM after S0ix entryDuncan Laurie
We are seeing an EC interrupt after setting the EC RAM offset that indicates that the EC should transition to S0ix mode and this is preventing the kernel from going into S0ix on the first try.

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.

2018-12-28ec/chromeec: fix LPC read/write for MEC devicesMatt DeVillier
Commit 8cf8aa2 [ec/google/chromeec: Use common MEC interface] changed the return mechanism for the checksum on reads/writes for MEC devices, but incorrectly handled the passed-in csum parameter by not dereferencing. This led to the returned csum value always being zero, which causes all EC commands with non- NULL data_in to fail with a checksum error. Fix this by storing the returned checksum in a temp variable, and only assigning to csum when the pointer isn't NULL; Test: build/boot google/chell, verify EC hello command succeeds, keyboard backlight turned on at boot.
