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.
