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: dwc2-usb: add USB_GADGET dependency

2016-06-29T08:11:41+00:00

The driver selects NOP_USB_XCEIV, which can only be built-in if
USB_GADGET is either disabled or also built-in, so with USB_DWC2_PCI=y
and USB_GADGET=m, NOP_USB_XCEIV is also built-in and we get this link
error:

drivers/usb/built-in.o: In function `nop_set_peripheral':
(text+0x1927c): undefined reference to `usb_gadget_vbus_connect'
drivers/usb/built-in.o: In function `nop_gpio_vbus_thread':
(text+0x197a0): undefined reference to `usb_gadget_vbus_connect'
(text+0x19830): undefined reference to `usb_gadget_vbus_disconnect'

This adds the same dependency for the dwc2 driver to avoid that
broken configuration.

usb: dwc2: remove dwc2_platform.ko

2015-04-29T20:20:11+00:00

As dwc2 pci module is now exporting dwc2 platform device, include
platform.o in dwc2-y and remove USB_DWC2_PLATFORM configuration
option. Driver will be built as two modules, dwc2.ko and dwc2_pci.ko.
dwc2.ko is the new platform driver.

Remove all EXPORT_SYMBOL_GPL as they are not needed any more.

usb: dwc2: pci: Select the generic PHY for dwc2-pci driver

The dwc2-pci driver requires the generic PHY. This fixes undefined

usb: dwc2: pci: Add device mode to the dwc2-pci driver

2015-03-11T20:08:17+00:00

The pci driver now registers a platform driver, like in dwc3, and lets
its probe function do all the initialization. This allows it to
account for changes to the platform driver that were not added to the
pci driver. Also future changes to the probe function don't have to be
duplicated. This also has the effect of adding device and DRD mode to
the pci driver. Tested on the Synopsys HAPS PCIe platform.

usb: dwc2: fix USB core dependencies

2015-01-30T16:36:44+00:00

It is currently possible to configure the dwc2 driver as built-in
when host mode or dual-role is enabled, but the USB core is
a loadable module. This leads to a link failure:

To fix the problem, this patch changes the dependencies so that
dwc2 host mode can only be enabled if either the USB core is
built-in or both USB and dwc2 are modules.

usb: dwc2: Update Kconfig to support dual-role

2014-11-14T21:00:07+00:00

Update DWC2 kconfig and makefile to support dual-role mode. The platform
file will always get compiled for the case where the controller is directly
connected to the CPU. So for loadable modules, dwc2.ko is built for host,
peripheral, and dual-role mode. The PCI bus interface will be called
dwc2_pci.ko and the platform interface module will be called dwc2_platform.ko.
