Peter Bigot 6e5db350b2 coccinelle: standardize k_sleep calls with integer timeouts 
Re-run with updated script to convert integer literal delay arguments to
k_sleep to use the standard timeout macros.

Enhanced Serial Peripheral Interface
####################################

Overview
********

This sample demonstrates how to use the Enhanced Serial Peripheral Interface
(eSPI) API.
It shows how to configure and select eSPI controller capabilities as part of
a simple eSPI handshake that includes exchanging virtual wire packets.

Standard platform signals are sent virtual wire packets over the bus.
Callbacks are registered that will write to the console indicating main
eSPI events and when a virtual wire is received.

Building and Running
********************

The sample can be built and executed on boards supporting eSPI.
Any pins required for minimum eSPI handshake should be configured.
