Subject: [PATCH v2 00/12] Synaptics RMI4 over SMBus

Hi,

This is the second version of Synaptics RMI4 over SMBus. There are few
differences compared to the previous submission:
- comments from Andrew are addressed
- fixed an oops when using the "rescan" feature from serio/drvctrl
- use alloc_ordered_workqueue instead of create_singlethread_workqueue

Dmitry, Elan has a similar binding mechanism (touchpad only declared as a PS/2
device, while it can be controlled over SMBus through elan_i2c.ko). I'd like
to have your opinion on using an intermediate platform driver to do the binding
from PS/2. It seems to me that it's the cleanest solution, but you may have
other hints. Note that in the Elan case, the platform driver will get much
simpler because there is no PS/2 passthrough device handled under SMBus (the
protocol is completely defined for the trackstick).

Cheers,
Benjamin
