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

[Christopher Heiny <cheiny@synaptics.com>]

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.
