It needs a small update to the Tegra device tree files (2 of the patches) and another change to deal with peripheral IDs (another 2 of the patches). I expect to get this done in the next few days.

[U-Boot] [PATCH v3 0/16] tegra: Add fdt definitions and USB driver
This series brings in the kernel fdt file and provides a working USB driver for Tegra2 Seaboard. (I have done this in one series since otherwise most of the fdt additions will just look like dead code.) The driver requires CONFIG_OF_CONTROL and a device tree to operate. Some enhancements to fdtdec are required to make this easier, and these are included in the series also. I have had to bring in basic GPIO support due to the request to put the USB VBUS into the fdt. Since the kernel recently got a very minimal USB binding, I have started with that and extended it where appropriate. Tegra likes to have cache-aligned buffers. I have dropped the patch which implements this since we will solve this problem by making callers align their buffers (as we did with MMC). Changes in v2: - Use "okay" instead of "ok" for fdt node status - Remove 0x from fdt aliases - Rename params to timing - Store entire fdt config in port list, not just register pointer - Remove non-fdt operation of USB, since it is not needed - Decode USB VBUS GPIO from the fdt - Decode phy type differently (to match new kernel fdt) - Rename tegra20-usb to tegra20-ehcui (to match new kernel fdt) - Improve debug() printouts in case of failure to init USB - Add setting of pinmux for USB VBUS GPIO - Remove unneeded CONFIG_TEGRA_USBx defines Changes in v3: - Remove "okay" from nodes since this is the default anyway - Fix device tree indenting with tabs instead of spaces - Disable USB2 which is not used on Seaboard - Remove usbparams properties from fdt and moved them to C code - Drop Tegra USB alignment patch as we will deal with this another way Simon Glass (16): fdt: Tidy up a few fdtdec problems fdt: Add functions to access phandles, arrays and bools Add gpio_request() to asm-generic header fdt: Add basic support for decoding GPIO definitions arm: fdt: Ensure that an embedded fdt is word-aligned arm: fdt: Add skeleton device tree file from kernel tegra: fdt: Add Tegra2x device tree file from kernel tegra: fdt: Add device tree file for Tegra2 Seaboard from kernel tegra: usb: fdt: Add additional device tree definitions for USB ports tegra: usb: fdt: Add USB definitions for Tegra2 Seaboard usb: Add support for txfifo threshold tegra: usb: Add support for Tegra USB peripheral tegra: usb: Add USB support to nvidia boards tegra: usb: Add common USB defines for tegra2 boards tegra: usb: Enable USB on Seaboard tegra: fdt: Enable FDT support for Seaboard README|3 + arch/arm/cpu/armv7/tegra2/Makefile|4 +- arch/arm/cpu/armv7/tegra2/config.mk |2 + arch/arm/cpu/armv7/tegra2/usb.c | 430 + arch/arm/cpu/armv7/u-boot.lds |5 + arch/arm/dts/skeleton.dtsi| 13 + arch/arm/dts/tegra20.dtsi | 172 arch/arm/include/asm/arch-tegra2/tegra2.h |2 + arch/arm/include/asm/arch-tegra2/usb.h| 255 + board/nvidia/common/board.c |8 + board/nvidia/dts/tegra2-seaboard.dts | 47 drivers/usb/host/Makefile |1 + drivers/usb/host/ehci-hcd.c |7 + drivers/usb/host/ehci-tegra.c | 63 + drivers/usb/host/ehci.h |6 +- dts/Makefile |2 +- include/asm-generic/gpio.h| 10 + include/configs/seaboard.h| 12 + include/configs/tegra2-common.h | 14 + include/fdtdec.h | 109 +++- lib/fdtdec.c | 168 +++- 21 files changed, 1320 insertions(+), 13 deletions(-) create mode 100644 arch/arm/cpu/armv7/tegra2/usb.c create mode 100644 arch/arm/dts/skeleton.dtsi create mode 100644 arch/arm/dts/tegra20.dtsi create mode 100644 arch/arm/include/asm/arch-tegra2/usb.h create mode 100644 board/nvidia/dts/tegra2-seaboard.dts create mode 100644 drivers/usb/host/ehci-tegra.c -- 1.7.3.1 ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
