Subject: [PATCH RFC 0/3] Input: add EKTP1059 Touchpad

Add a driver and bindings for the Touchpad found in the Epson Moverio
BT-200. The only information source is the driver in the vendor kernel.
Besides of cleanup it differs from it by not doing much postprocessing.

The touchpad has no buttons and can react to three simultanous touches
but positions can be used only for two touches.

This is an early RFC, maybe somebody recognizes something from other
ELAN chips.
