Benjamin Tissoires 522214d9be Input: rmi4 - f30: detect INPUT_PROP_BUTTONPAD from the button count
INPUT_PROP_BUTTONPAD is currently only set through the platform data.
The RMI4 header doc says that this property is there to force the
buttonpad property, so we also need to detect it by looking at
the exported buttons count.

Benjamin Tissoires 81dec809aa Input: synaptics-rmi4 - forward upper mechanical buttons to PS/2 guest
On the latest series of ThinkPads, the button events for the TrackPoint
are reported through the touchpad itself as opposed to the TrackPoint
device. In order to report these buttons properly, we need to forward
them to the TrackPoint device and notify psmouse to send the button
presses/releases.

Dmitry Torokhov bf3e8502ee Input: synaptics-rmi4 - clean up F30 implementation
This patch does several cleanup changes to F30 code

- switch to using BIT() macro
- use DIV_ROUND_UP() where appropriate
- factor out code setting up and reporting buttons
- use single loop when reporting buttons: arithmetic is cheap compared to
  conditionals and associated branch misprediction.

Benjamin Tissoires ae9979c310 Input: synaptics-rmi4 - store the attn data in the driver
Now that we have a proper API to set the attention data, there is
no point in keeping it in the transport driver.

Benjamin Tissoires 0a135b88bc Input: synaptics-rmi4 - have only one struct platform data
If struct rmi_device_platform_data contains pointers to other struct,
it gets difficult to allocate a fixed size struct and copy it over between
drivers.

Change the pointers into a struct and change the code in rmi4 accordingly.

Andrew Duggan 6d0dbeae71 Input: synaptics-rmi4 - handle incomplete input data
Commit 5b65c2a029 ("HID: rmi: check sanity of the incoming report") added
support for handling incomplete HID reports do to the input data being
corrupted in transit. This patch reimplements this functionality in the
function drivers so they can handle getting less valid data then they
expect.

Andrew Duggan 562b42d3ee Input: synaptics-rmi4 - add support for F30
RMI4 F30 supports input from clickpad buttons and controls LEDs located
on the touchpad PCB. This patch adds support of the clickpad buttons and
defers supporting LEDs for the future.
