the following patch was just integrated into master: commit fbf2c79b489a526e5ab7359ce56be0b4b66c854b Author: Duncan Laurie firstname.lastname@example.org Date: Mon Sep 26 10:31:22 2016 -0700
drivers/i2c/generic: Add config for marking device as probed
Add a config option to the generic I2C device driver to indicate to the OS that this device should be probed before being added.
This can be used to provide ACPI device instantiations to devices that may not actually exist on the board. For example, if multiple trackpad vendors are supported on the same board they can both be described in ACPI and the OS will probe the address and load the driver only if the device responds to the probe at that address.
