4 Subject: [PATCH] dtoverlays: Add overlays for Pimoroni Hyperpixel
5 displays
6
7 Adds an overlays for the Pimoroni HyperPixel4, HyperPixel 4
8 Square, and HyperPixel 2 Round DPI displays.
9
10 We have a conflict over the use of GPIO 27 for touch screen
11 interrupt and SPI CLK for configuring the display on the
12 two HyperPixel4 displays.
