Interfacing (DSI, CSI, I2C, etc.) • Re: Using I2C with the BQ27441, Raspberry Pi 4

Thank you for the reply.

I am new to the device tree but it seems like there is conflicting information on whether it is possible to change the device tree without recompiling the kernel. This is a new question, but what are the steps to changing the device tree? I believe they are:

• Edit <my-board>.dts

• Compile the dts to dtb with dtc -I dts -O dtb -o <my-board>.dtb <my-board>.dts

• move <my-board>.dtb to /sys/kernel/config/device-tree/overlays

Is this correct? Am I missing a step? Am I completely wrong?
