Now we have moved all of the i.MX SoCs into chipidea driver. It would make things a lot simpler if MPC could be moved to chipidea driver as well so that fsl_udc_core.c could go away. > > I checked out the arch/powerpc/boot/dts/mpc8308rdb.dts for the RDB and it is > claiming a compatibility of fsl-usb2-dr. > > What would you recommend I use as a new device tree node/compatible string? Take a look at the existing bindings of i.MX. You probably only needs to add the drivers/usb/chipidea/ci_hdrc_imx.c equivalent for MPC. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
