{{PageHeader|Selecting DSI/LVDS display on VisionSOM-iMX93}}

The default Yocto system for VisionSOM-iMX93 has three display configurations written in the following kernel device tree files:

* No display: ''visionsom-imx93-cb-std.dts''
* SL-TFT7-TP-600-1024-LVDS display: ''visionsom-imx93-cb-std-lvds-rvt70hslnwc00-b.dts''
* SL-TFT7-TP-600-1024-MIPI display: ''visionsom-imx93-cb-std-mipi-rvt70hsmnwc00.dts''


The active device tree is selected by u-boot according to hardware setup:

{| class="wikitable"
|-
! 0x41 address on I2C1 !! GPIO2_IO07 pin state || dts used
|-
| inactive || - || visionsom-imx93-cb-std.dts
|-
| active || high || visionsom-imx93-cb-std-mipi-rvt70hsmnwc00.dts
|-
| active || low || visionsom-imx93-cb-std-lvds-rvt70hslnwc00-b.dts
|-
|}

Address 0x41 on I2C1 is used by ILI2132A touch panel controller on both LVDS/DSI connectors.

GPIO2_IO07 pin (GPIO_COMM pin 3) has an internal pull-up enabled be u-boot. It can be set to low state by connecting it to GND available on GPIO_COMM pin 1.
