This series adds support for the Hynitron cstxxx (specifically
the cst3xx series). The cst3xx supports 5 point multitouch with
hardware tracking of touch points.

Note that a datasheet was unavailable for this device, so it was
built based on vendor provided source code that was tagged as GPLv2.
Some of the register functions were discovered via trial and error
and labelled as such.

Chris Morgan (3):
  dt-bindings: vendor-prefixes: add Hynitron vendor prefix
  dt-bindings: input: touchscreen: Add Hynitron cstxxx bindings
  input/touchscreen: Add Hynitron cstxxx touchscreen
