Subject: [PATCH] dt-bindings: input: iqs269a: Add bindings for OTP variants
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.
