I understand you are busy with many other projects, but it would be
great if we could have this series (or a subset of this series)
landing ASAP.

We already have at least 2 machines (the Lenovo X1 Tablet and the HP
Pavilion x2) that need to be using the function 12 in Synaptics RMI4,
and so this series is a requirement to enable those touchpads.

If you really want to postpone the review of the new files in this
series, I think merging only the following patches would be
acceptable:
[v3,01/18] Input: synaptics-rmi4 - Move IRQ handling to rmi_driver
[v3,02/18] Input: synaptics-rmi4 - factor out functions from probe
[v3,03/18] Input: synaptics-rmi4 - Handle incomplete input data
[v3,04/18] Input: synaptics-rmi4 - Add parameters for dribble packets
and palm detect gesture
[v3,05/18] Input: synaptics-rmi4 - Add support for controlling dribble
packets in F12
[v3,06/18] Input: synaptics-rmi4 - Set the ABS_MT_TOOL_TYPE bit to
report tool type
[v3,09/18] Input: synaptics-rmi4 - have only one struct platform data
[v3,18/18] Input: synaptics-rmi4 - fix documentation of
rmi_2d_sensor_platform_data

This is the bare minimum I think to enable the F12 in hid-rmi. It
should apply gracefully (crossing finger for 9/18), and would allow us
to switch hid-rmi to rmi4-core.

I guess Jiri will probably want a stable branch with those commits so
we can also merge the switch from hid-rmi to use rmi4-core in v4.10.

Cheers,
Benjamin
