* pinctrl: rockchip: add support for new DT bindingsBeniamino Galvani2014-09-012-36/+18
| | | | | | | | | This patch modifies the Rockchip pinctrl driver to comply with the new DT bindings, which use two syscon nodes to specify the address of memory resources. Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mfd: syscon: add device tree supportBeniamino Galvani2014-09-011-0/+6

| * USB: host: add xHCI HCD, Hub, and platform driverSebastian Hesselbarth2014-07-285-0/+3447
| | | | | | | | | | | | | | | | | | | | 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.

| * USB: EHCI: use min3 from LinuxSebastian Hesselbarth2014-07-281-11/+1
| | | | | | | | | | | | | | | | | | EHCI HCD has a private version of min3() determining the smallest number out of 3. We already have min()/max() imported from Linux, also get min3()/max3() and use it instead of EHCI's private one.

| * 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.

| * USB: Fix stale usb devices in usb_device_listSebastian Hesselbarth2014-07-281-0/+1
| | | | | | | | | | | | | | | | | | New usb devices are added to a list of usb devices, but when removing the corresponding usb_device it was not removed from that list. Fix it by deleting it properly from the usb_device_list. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * USB: Use descriptors from ch11.hSebastian Hesselbarth2014-07-242-7/+7
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | usb_hub_configure() gets the hub descriptor and copies its values over to a local descriptor. While copying PortPowerCtrlMask it erroneously overwrites DeviceRemovable due to a copy-and-paste error. Fix it up.

Previously these were configured with arguments to the usbserial and dfu command. The parameters are device static, so it's nice to configure it somewhere in the environment instead of when calling dfu/usbserial.
