| MIPI-DBI Mode C compatible SPI controller. This driver emulates MIPI DBI |
| mode C using a SPI controller and GPIO pins |
| compatible: "zephyr,mipi-dbi-spi" |
| |
| include: ["mipi-dbi-controller.yaml", "pinctrl-device.yaml"] |
| |
| properties: |
| spi-dev: |
| type: phandle |
| required: true |
| description: | |
| SPI device to use for data transfers with MIPI DBI commands. This SPI |
| device should be connected to the MIPI DBI display. |

| dc-gpios: |
| type: phandle-array |
| description: | |
| Data/command gpio pin. Required when using 4 wire SPI mode (Mode C1). |
| Set to low when sending a command, or high when sending data. |

| reset-gpios: |
| type: phandle-array |
| description: | |
| Reset GPIO pin. Set high to reset the display |
| |
| write-only: |
| type: boolean |
| description: | |
| Only writes to display controller, do not perform reads. |
| If all controllers are write-only, read functions will be |
| optimized out for size. |
| It can also be used as an alternative to half duplex when |
| only one data line is connected. |
