[U-Boot] [PATCH v4 16/20] tegra: usb: Add support for Tegra USB peripheral

[Remy Bohmer]

Hi,

2012/1/12 Simon Glass <sjg at chromium.org>:
> This adds basic support for the Tegra2 USB controller. Board files should
> call board_usb_init() to set things up.
>
> Configuration is performed through the FDT, with aliases used to set the
> order of the ports, like this fragment:
>
>        aliases {
>                /* This defines the order of our USB ports */
>                usb0 = "/usb at 0xc5008000";
>                usb1 = "/usb at 0xc5000000";
>        };

> Changes in v2:
> - 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
>
> Changes in v3:
> - Remove usbparams properties from fdt and moved them to C code
>
> Changes in v4:
> - Use updated fdtdec alias functiona to get USB aliases
> - Use peripheral clock node to obtain peripheral ID
