description: ST7735R 160x128 display controller
compatible: "sitronix,st7735r"
include: [spi-device.yaml, display-controller.yaml]
properties:
reset-gpios:
type: phandle-array
required: true
description: RESET pin.
The RESET pin of ST7735R is active low.
If connected directly the MCU pin should be configured
as active low.
cmd-data-gpios:
type: phandle-array
required: true
description: D/CX pin.
The D/CX pin of ST7735R is active low (transmission command byte).
If connected directly the MCU pin should be configured
as active low.

Enable Display Inversion

Inverting color format order (RGB->BGR or BGR->RGB)
In the case of enabling this option, API reports pixel-format in capabilities
as the inverted value of the RGB pixel-format specified in MADCTL.
This option is convenient for supporting displays with bugs
where the actual color is different from the pixel format of MADCTL.
