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.

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().
