From 1c1cce99d43e8a39b7cbd8d1440b7a458f7abd3a Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 27 Feb 2012 10:52:45 +0000 Subject: [PATCH] tegra: usb: fdt: Add additional device tree definitions for USB ports This adds clock references to the USB part of the device tree for U-Boot, and marks USB1 as supporting legacy mode (which we disable in the driver). The USB timing information may vary between boards sometimes, but for now we hard-code it in C. This is because all current T2x boards use the same values, we will deal with T3x later and we first need to agree on the format for this timing information in the fdt and may in fact decide that it has no place there.
