[PATCH 07/10] rpi: Enable USB Power domain during startup

Enable the USB Power domain during startup. The power domain is abstracted as a regulator in barebox, but modelled as a power domain in the device tree. Until this is sorted out just enable the power domain or regulator in the board code. Signed-off-by: Sascha Hauer --- arch/arm/boards/raspberry

[PATCH 03/10] device: Introduce dma_offset

For devices that do not have a 1:1 mapping between DMA and CPU we need a dma_offset. This adds dma_offset to struct device_d and starts honoring it in ARM dma_(un)map_single(). Also we add some comments to functions that would normally need a device argument to make the DMA <-> CPU translations dev

[PATCH 00/10] Add Raspberry Pi USB support

This series adds USB host support for the Raspberry Pi. The dwc2 USB host driver is ported from U-Boot and tested on a Raspberry Pi 3b with the USB ethernet adapter found on that board. Finally we have ethernet support on the Raspberry Pi \o/ Sascha Sascha Hauer (10): usb: Make timeout unit cl
