Subject: [RFC PATCH 04/06] input/rmi4: Config files and makefiles

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.
