My customer is using i.MX6Q and their software is based on Linux(L 3.14.28).
My customer is trying to reduce communication speed of USB to 12MBps(Full-speed).
They want to fix the speed to ‘full-speed’ due to its anti-noise capability.
They have wrote the followings into &usbhi and &usbotg in DTSI file, but the speed was still ‘hi speed(480Mbps)’.
Could you show me how to fix the speed into ‘full-speed’?
And could show me why the speed does not fix to full-speed when they wrote as above?
Actually, they have achieved by modifying usb/chipidea/core.c file.
But they still need to know the way they did is right.
