[PATCH 3/6] dt-bindings: input: iqs269a: Add bindings for OTP variants

Jeff LaBundy
2020-08-16T21:15:20Z

This patch adds bindings for the D0 order code of the device. This
order code represents an OTP variant that enables a touch-and-hold
function in place of slider 1.

Also included is the ability to specify the 00 order code (default
option with no OTP customization) explicitly.
