Not much to say here, except that we've reduced the number of different
Kconfig options, which will hopefully make it easier to configure RMI4
support in kernels.

+config RMI4_BUS
+ bool "Synaptics RMI4 bus support"
+ help
+ Say Y here if you want to support the Synaptics RMI4 bus. This is
+ required for all RMI4 device support.
+
+ If unsure, say Y.
+
+ This feature is not currently available as a loadable module.
+
+config RMI4_DEBUG
+ bool "RMI4 Debugging"
+ depends on RMI4_BUS
+ help
+ Say Y here to enable debug feature in the RMI4 driver.
+
+ Note that the RMI4 driver debug features can generate a lot of
+ output (potentially clogging up your dmesg output) and generally
+ slow down driver operation. It's recommended to enable them only
+ if you are actively developing/debugging RMI4 features.
+
+ If unsure, say N.
+
+config RMI4_I2C
+ bool "RMI4 I2C Support"
+ depends on RMI4_BUS && I2C
+ help
+ Say Y here if you want to support RMI4 devices connected to an I2C
+ bus.
+
+ If unsure, say Y.
+
+ This feature is not currently available as a loadable module.
+
+config RMI4_GENERIC
+ bool "RMI4 Generic driver"
+ depends on RMI4_BUS
+ help
+ Say Y here if you want to support generic RMI4 devices.
+
+ This is pretty much required if you want to do anything useful with
+ your RMI device.
+
+ This feature is not currently available as a loadable module.
+
+config RMI4_F11
+ tristate "RMI4 Function 11 (2D pointing)"
+ depends on RMI4_BUS && RMI4_GENERIC
+ help
+ Say Y here if you want to add support for RMI4 function 11.
+
+ Function 11 provides 2D multifinger pointing for touchscreens and
+ touchpads. For sensors that support relative pointing, F11 also
+ provides mouse input.
+
+ To compile this driver as a module, choose M here: the
+ module will be called rmi-f11.
+
+config RMI4_F11_PEN
+ bool "RMI4 F11 Pen Support"
+ depends on RMI4_F11
+ help
+ Say Y here to add support for pen input to RMI4 function 11.
+
+ If this feature is enabled, when pen inputs are detected they
+ will be reported to the input stream as MT_TOOL_PEN. Otherwise,
+ pens will be treated the same as fingers.
+
+ Not all UI implementations deal gracefully with pen discrimination.
+ If your system is not recognizing pen touches and you know your
+ sensor supports pen input, you probably want to turn this feature
+ off.
+
+config RMI4_VIRTUAL_BUTTON
+ tristate "RMI4 Vitual Button"
+ depends on RMI4_F11
+ help
+ Say Y here if you want to add support for RMI4 virtual button to F11.
+
+ The virtual button feature implement the virtual button device in
+ certain RMI4 touch sensors.
+
+ This works only if your sensor supports F11 gestures.
