usb: host: Allow to build ehci orion with mvebu SoCs

2017-03-17T04:32:59+00:00

The mvebu ARM64 SoCs no longer select PLAT_ORION. However Armada 37xx use
the Orion EHCI controller. This patch allows the Orion EHCI driver to be
built when ARCH_MVEBU is selected.

usb: add CONFIG_USB_PCI for system have both PCI HW and non-PCI based USB HW

2017-03-17T04:16:56+00:00

a lot of embeded system SOC (e.g. freescale T2080) have both
PCI and USB modules. But USB module is controlled by registers directly,
it have no relationship with PCI module.

when say N here it will not build PCI related code in USB driver.

usb: make the MTK XHCI driver compile for older MIPS SoCs

2017-01-10T16:00:41+00:00

The MIPS based MT7621 shares the same XHCI core as the newer generation of
ARM based SoCs. The driver works out of the box and we only need to make it
buildable in Kconfig.

USB: OHCI: make ohci-da8xx a separate driver

2016-10-27T14:59:59+00:00

Separate the Davinci OHCI host controller driver from ohci-hcd
host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM

usb: ohci-da8xx: Remove code that references mach

2016-10-24T13:17:51+00:00

Including mach/* is frowned upon in device drivers, so get rid of it.

This replaces usb20_clk and code that pokes CFGCHIP2 with a proper phy
driver.

usb: gadget: move gadget API functions to udc-core

2016-06-21T07:38:34+00:00

instead of defining all functions as static inlines,
let's move them to udc-core and export them with
EXPORT_SYMBOL_GPL, that way we can make sure that
only GPL drivers will use them.

As a side effect, it'll be nicer to add tracepoints
to the gadget API.

While at that, also fix Kconfig dependencies to
avoid randconfig build failures.

usb: host: xhci-rcar: Avoid long wait in xhci_reset()

2016-05-09T11:08:46+00:00

The firmware of R-Car USB 3.0 host controller will control the reset.
So, if the xhci driver doesn't do firmware downloading (e.g. kernel
configuration is CONFIG_USB_XHCI_PLATFORM=y and CONFIG_USB_XHCI_RCAR
is not set), the reset of USB 3.0 host controller doesn't work
correctly. Then, the host controller will cause long wait in
xhci_reset() because the CMD_RESET bit of op_regs->command is not
cleared for 10 seconds.

So, this patch modifies the Kconfig to enable both CONFIG_USB_XHCI_PLATFORM
and CONFIG_USB_XHCI_RCAR.

usb: xhci: Add NVIDIA Tegra XUSB controller driver

2016-04-29T14:48:58+00:00

Add support for the on-chip XUSB controller present on Tegra SoCs. This
controller, when loaded with external firmware, exposes an interface
compliant with xHCI. This driver loads the firmware, starts the
controller, and is able to service host-specific messages sent by the
controller's firmware.

The controller also supports USB device mode as well as powergating
of the SuperSpeed and host-controller logic when not in use, but
support for these is not yet implemented.
