+Subject: [PATCH] dtoverlays: Add overlays for Pimoroni Hyperpixel
+ displays
+
+Adds an overlays for the Pimoroni HyperPixel4, HyperPixel 4
+Square, and HyperPixel 2 Round DPI displays.
+
+We have a conflict over the use of GPIO 27 for touch screen
+interrupt and SPI CLK for configuring the display on the
+two HyperPixel4 displays.
