Can you point me to which socs you are facing issues ? > Hi Ramneek, In fact, there is no device tree support for i.mx usb driver. We plan to move all PHY's operation to PHY driver once the generic PHY driver has mainlined. It is better only do controller(chipidea IP) related operation at fsl_udc_core.c as every SoC may has different PHY. I just don't want your patch to break current user, you will find there is #ifndef CONFIG_ARCH_MXC condition to usb_sys_regs at current code. [Ramneek]: Ok Shawn, let me see how I can incorporate this to make sure that this code also works for IMX.
