      usb: Introduce DesignWare USB3 DRD Driver · 72246da4
      由 Felipe Balbi 提交于 
      The DesignWare USB3 is a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.

Several other parameters can be configured
like amount of FIFO space, amount of TX and
RX endpoints, amount of Host Interrupters,
etc.

The current driver has been validated with
a virtual model of version 1.73a of that core
and with an FPGA burned with version 1.83a
of the DRD core. We have support for PCIe
bus, which is used on FPGA prototyping, and
for the OMAP5, more adaptation (or glue)
layers can be easily added and the driver
is half prepared to handle any possible
configuration the HW engineer has chosen
considering we have the information on
one of the GHWPARAMS registers to do
runtime checking of certain features.

More runtime checks can, and should, be added
in order to make this driver even more flexible
with regards to number of endpoints, FIFO sizes,
transfer types, etc.

While this supports only the device side, for
now, we will add support for Host side (xHCI -
see the updated series Sebastian has sent [1])
and OTG after we have it all stabilized.

      usb: gadget: allow multiple gadgets to be built · 193ab2a6
      由 Felipe Balbi 提交于 
      now that we have the udc class, we can allow
multiple gadget controller drivers to be
compiled as modules. This will allow for
distro-like kernels for embedded devices.

With this patch, I managed to build an x86
kernel with support for many of the controllers
enabled:

CONFIG_USB_FUSB300=m
CONFIG_USB_R8A66597=m
CONFIG_USB_M66592=m
CONFIG_USB_AMD5536UDC=m
CONFIG_USB_CI13XXX_PCI=m
CONFIG_USB_NET2272=m
CONFIG_USB_NET2280=m
CONFIG_USB_GOKU=m
CONFIG_USB_LANGWELL=m
CONFIG_USB_EG20T=m

Also an ARM kernel with support for many controllers:

CONFIG_USB_FUSB300=m
CONFIG_USB_OMAP=m
CONFIG_USB_R8A66597=m
CONFIG_USB_GADGET_MUSB_HDRC=m
CONFIG_USB_M66592=m
CONFIG_USB_NET2272=m
CONFIG_USB_DUMMY_HCD=m

The next step would be to get rid of the
direct access to arch/ and mach/ directories
on some gadget controllers so that we can
build all of them without depending on their
respective ARCH_* symbols.

      USB: add USB EHCI support for MPC5121 SoC · 230f7ede
      由 Anatolij Gustschin 提交于 
      Extends FSL EHCI platform driver glue layer to support
MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI
registers are in big endian format. The appropriate flags
are set using the information in the platform data structure.
MPC83xx system interface registers are not available on
MPC512x, so the access to these registers is isolated in
MPC512x case. Furthermore the USB controller clocks
must be enabled before 512x register accesses which is
done by providing platform specific init callback.

The MPC512x internal USB PHY doesn't provide supply voltage.
For boards using different power switches allow specifying
DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal
PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault"
properties in the device tree USB nodes. Adds documentation
for this new device tree bindings.
