IMX8MM disable PCIe,MIPI,CSI

[mahesh_rd]

Hi,

We are working on a custom board based on the i.MX8M Mini Processor [MIMX8MM3CVTKZAA]. We only require 3 UART, 3 SPI and 3 I2C lines. We do not need VPU, GPU,PCIe, MIPI,Bluetooth, etc nodes. Is there any way I can disable these devices in DTS or/and Kernel so that I can have a minimal kernel?

Thank you so much Igor.

Hi mahesh_rd

in device tree it can be changed from status = "okay" to status = "disabled".

In kernel one can look at section "Menu Configuration Options"  i.MX Linux Reference Manual​

description of each module.

Best regards
