Child nodes describe individual peripherals on that bus. This document will define the syntax used to represent a DSI bus in a device tree. It is important that you create new questions related to the Colibri iMX8X sample in this space.

This book contains many real life examples derived from the author’s experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. While editing my device tree to figure this problem out, I run a new menuconfig.

DSI host In addition to the standard properties and those defined by the parent bus of a DSI host, the following properties apply to a node representing a DSI host. Hence the value of this property should be 1. The number of cells required to represent an address on the bus. Please visit this page to clear all LQ-related cookies. These two lines are the same no matter linix the display are connected or not, and the driver module line shows up two times.

Progress I have limited progress on this project, I have decided to keep a copy of the kernel source in a git repository and edit the files there, this was chosen to keep track of what I am doing. The virtual channel number of a DSI peripheral. You are currently viewing LQ as a guest. The time now is The device tree now seems to compile fine, mipj nothing more happens.

Does anyone have suggestions to what might be missing?

Properties described here apply to all DSI peripherals, but individual bindings may want to define additional, device-specific properties. The DSI host controller’s node contains a set mjpi properties that characterize the bus. Follow Follow this Question.

The first cell of each entry in the reg property is the number of the first virtual channel and the second cell is the number of consecutive virtual channels. If you’d like to contribute content, let us know. Thank you very much! I even tried to introduce errors in the device tree to force a compilation error, this did not work so I am reasonably certain that the device tree relating to mipi does not compile.
