* ARM: move DMA alloc functions to dma.hLucas Stach2015-03-065-2/+6
| | | | | | | | | | This better separates the DMA from the MMU functionality. Also move all drivers that only depends on asm/mmu.h for the alloc functions over to the common header. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: change dma_alloc/free_coherent to match other architecturesLucas Stach2015-03-064-11/+17
| | | | | | | | | As a lot drivers currently rely on the 1:1 virt->phys mapping on ARM we define DMA_ADDRESS_BROKEN to mark them. In order to use them on other architectures with a different mapping they need proper fixing. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | USB: MUSB: Add barebox specific changesSascha Hauer2014-09-2619-3831/+898
| | | | | | | | | | | | | | | | | | | | | | This changes the MUSB support from the original Kernel state to be usable with barebox. Tested on a custom board and the Beaglebone Black. The host port on the Beaglebone works, the OTG port works in device mode, but not yet in host mode. Based on the initial MUSB port from Rolf Evers Fischer.

* | USB: Add MUSB driver from LinuxSascha Hauer2014-09-2614-0/+11146

* | USB: gadget: allow multiple udc driversSascha Hauer2014-09-261-9/+3
| | | | | | | | | | | | | | | | | | | | Since the MUSB driver will have it's own directory the Kconfig entries won't be in drivers/usb/gadget/Kconfig. This is incompatible with the current 'choice' approach for udc drivers. The udc drivers do not implement the global usb_gadget_poll() anymore, so we can drop the choice and allow multiple gadget drivers. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | This adds support for xHCI USB 3.0 host controllers found on various SoCs and PCI devices. Currently, the driver only supports the virtual USB 2.0 ports of the host controller, so if you plan to use USB 3.0 devices, put a USB 2.0 cable in between.

| | | | | | | | | | | | | | | | | | EHCI HCD has a private version of min3() determining the smallest number out of 3.

| * USB: improve error paths and tear-downSebastian Hesselbarth2014-07-283-27/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB core isn't too strict about allocation/deallocation and add/remove sequences of usb devices. Especially, error paths and device tear-down are kind of broken and cause hangs on failing usb device detect. This patch improves the situation by introducing a usb_free_device() that tears down allocated resources by usb_alloc_new_device(). usb_remove_device() now only deals with resources that have been added by usb_new_device(). Also, error handling is fixed or improved to ensure that no devices are unregistered that have not been previously registered.

| * USB: Count detected USB devices independent of dev_indexSebastian Hesselbarth2014-07-281-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Adding a usb device increases dev_index every time a new device is allocated. Removing a usb device does not decrease again, of course. As we print the number of detected usb devices after each usb bus scan based on dev_index, we cannot trust dev_index here. Keep track of the correct number of (currently) detected usb devices by introducing an independent dev_count that gets increased on detect and decreased on remove.

| | | | | | | | | | | | | | | | | | Use the descriptors from ch11.h instead of duplicating them in usb.h. usb_hub_descriptor now contains a union .u to differentiate HS hub descriptor from SS hub descriptor.

| * USB: EHCI: make use of defines for descriptorsSebastian Hesselbarth2014-07-241-52/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have a full set of defines for each descriptor field, make use of it for the EHCI HCD descriptors. This fixes endianess issues for .device.bcdUSB, .device.bcdDevice, .config.wTotalLength, and .endpoint.wMaxPacketSize. Also, .endpoint.bInterval was set to 0 instead of 255 due to a copy-and-paste error while assigning u8[] to usb_endpoint_descriptor. This also is a preparation for including ch11.h later, which has a modified usb_hub_descriptor for USB 3.0.
