* CrOS EC:
- Add new CrOS ISHTP transport protocol
- Add proper documentation for debugfs entries and expose resume and uptime files
- Select LPC transport protocol variant at runtime.
- Add lid angle sensor driver
- Fix oops on suspend/resume for lightbar driver
- Set CrOS SPI transport protol in realtime
* Wilco EC:
- Add telemetry char device interface
- Add support for event handling
- Add new sysfs attributes
* Misc:
- Contains ib-mfd-cros-v5.3 immutable branch from mfd, with cros_ec_commands.h
header freshly synced with Chrome OS's EC project.

config WILCO_EC

|
help
|
|
If you say Y here, you get support for talking to the ChromeOS
|
|
Wilco EC over an eSPI bus. This uses a simple byte-level protocol
|
|
with a checksum.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called wilco_ec.

depends on WILCO_EC
|
|
help
|
|
If you say Y here, you get support for sending raw commands to
|
|
the Wilco EC via debugfs. These commands do not do any byte
|
|
manipulation and allow for testing arbitrary commands. This
|
|
interface is intended for debug only and will not be present
|
|
on production devices.

|
|
help
|
|
If you say Y here, you get support for the EC to send events
|
|
(such as power state changes) to userspace. The EC sends the events
|
|
over ACPI, and a driver queues up the events to be read by a
|
|
userspace daemon from /dev/wilco_event using read() and poll().

If you say Y here, you get support to query EC telemetry data from
|
|
/dev/wilco_telem0 using write() and then read().
