4	depends on ACPI && X86 && CROS_EC_LPC
5	help
6	  If you say Y here, you get support for talking to the ChromeOS
7	  Wilco EC over an eSPI bus. This uses a simple byte-level protocol
8	  with a checksum.

11	  module will be called wilco_ec.

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

23config WILCO_EC_EVENTS
24	tristate "Enable event forwarding from EC to userspace"
25	depends on WILCO_EC
26	help
27	  If you say Y here, you get support for the EC to send events
28	  (such as power state changes) to userspace. The EC sends the events
29	  over ACPI, and a driver queues up the events to be read by a
30	  userspace daemon from /dev/wilco_event using read() and poll().

32config WILCO_EC_TELEMETRY

34	depends on WILCO_EC
35	help
36	  If you say Y here, you get support to query EC telemetry data from
37	  /dev/wilco_telem0 using write() and then read().
