From e5354107e14755991da82e0d2a4791db92908d9d Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Wed, 27 Mar 2013 17:29:53 +0200 Subject: mei: bus: Initial MEI Client bus type implementation mei client bus will present some of the mei clients as devices for other standard subsystems Implement the probe, remove, match, device addtion routines, along with the sysfs and uevent ones. mei_cl_device_id is also added to mod_devicetable.h A mei-cleint-bus.txt document describing the rationale and the API usage is also added while ABI/testing/sysfs-bus-mei describeis the modalias ABI.
