config WILCO_EC tristate "ChromeOS Wilco Embedded Controller" depends on ACPI && X86 && CROS_EC_LPC && CROS_EC_LPC_MEC 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. config WILCO_EC_DEBUGFS tristate "Enable raw access to EC via debugfs" 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. config WILCO_EC_EVENTS tristate "Enable event forwarding from EC to userspace" depends on WILCO_EC 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(). config WILCO_EC_TELEMETRY tristate "Enable querying telemetry data from EC" depends on WILCO_EC help If you say Y here, you get support to query EC telemetry data from /dev/wilco_telem0 using write() and then read().
