[U-Boot] [PATCH v2 13/17] tegra: usb: Add support for Tegra USB peripheral

[Remy Bohmer]

Hi,

2011/12/3 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 through FDT and CONFIG is supported. For FDT, the device
> tree aliases set the order of the port, like this fragment:
>
>        aliases {
>                /* This defines the order of our USB ports */
>                usb0 = "/usb at 0xc5008000";
>                usb1 = "/usb at 0xc5000000";
>        };
>
> For CONFIG-based configuration, where CONFIG_OF_CONTROL is not defined,
> USB ports rely on CONFIG_TEGRA2_USBx macros to select the ordering.
> For example:
>
>        #define CONFIG_TEGRA_USB0       TEGRA_USB3_BASE
>        #define CONFIG_TEGRA_USB1       TEGRA_USB1_BASE
>
> We record the order that the ports are configured and use that to select
> ports by number.

> 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
