Do you really read the usb porting guide? Your reply sounds like you didn’t read it.
I have read porting guide, Is there something wrong with my device tree?
You need to give that regulator to the vbus-supply inside the usb controller. Otherwise it won’t know there is such regulator…
Whether this setting is feasible?but the problem is the same as before.
Can you just attach your full dts file, full schematic and current dmesg? Stop sharing these picture one by one.
Thanks for the support, The problem has been solved.
Please share how you resolve this issue.
I’m terribly sorry for my carelessness, In tegra-p1001-disp.dtsi file, I used the devkit fixed-regulator dtsi file，in fact we used the modified file on custom board.
