[U-Boot] [PATCH v3 0/16] tegra: Add fdt definitions and USB driver

[Marek Vasut <marex@denx.de>]

> 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
