From 69bec725985324e79b1c47ea287815ac4ddb0521 Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Fri, 19 Feb 2016 17:26:15 +0800 Subject: USB: core: let USB device know device node Although most of USB devices are hot-plug's, there are still some devices are hard wired on the board, eg, for HSIC and SSIC interface USB devices. If these kinds of USB devices are multiple functions, and they can supply other interfaces like i2c, gpios for other devices, we may need to describe these at device tree. In this commit, it uses "reg" in dts as physical port number to match the phyiscal port number decided by USB core, if they are the same, then the device node is for the device we are creating for USB core.
