From eda2e30c6684d67288edb841c6125d48c608a242 Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Mon, 2 Sep 2019 11:53:02 +0200 Subject: mfd / platform: cros_ec: Miscellaneous character device to talk with the EC That's a driver to talk with the ChromeOS Embedded Controller via a miscellaneous character device, it creates an entry in /dev for every instance and implements basic file operations for communicating with the Embedded Controller with an userspace application. The API is moved to the uapi folder, which is supposed to contain the user space API of the kernel. Note that this will replace current character device interface implemented in the cros-ec-dev driver in the MFD subsystem. The idea is to move all the functionality that extends the bounds of what MFD was designed to platform/chrome subsystem.
