Hi,
2012/1/12 Simon Glass sjg@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@0xc5008000"; usb1 = "/usb@0xc5000000"; };
drivers/usb/host files ONLY: Acked-by: Remy Bohmer linux@bohmer.net Signed-off-by: Simon Glass sjg@chromium.org
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
