From 432995c14aa5bc88fcf1fa170cf18411e094cad9 Mon Sep 17 00:00:00 2001
From: Melissa LeBlanc-Williams <melissa@adafruit.com>

Subject: [PATCH 0875/1002] Update touch PiTFT overlays
Expose the invert and swap touch parameters on 2.8" and 3.5" resistive touchscreens. Add
the DRM parameter to the PiTFT 2.2" and 2.8" Capacitive overlay in the same
way it is on the resistive overlays. Change the DRM driver to `adafruit,yx240qv29`
because the rotations are consistent with the FBTFT Driver. Fix the override size parameters
on the 2.8" capacitive PiTFT.
