2015-03-19usb: dwc2: pci: Correctly compile dwc2-pci as a module or built-inJohn Youn
The dwc2-pci driver should be compiled as a module when configured to do so. If the dwc2-pci is configured as a module but actually built-in, it can cause build errors due to the fact that the generic-phy will be allowed to compile as a module causing undefined references.

2015-03-19usb: dwc2: avoid leaking DMA channels on disconnectionVincent Palatin
When the HCD is disconnected, the DMA transfers still in-flight were cleaned-up but the count of available DMA channels (e.g. available_host_channels) was not reset. The pool of DMA channels can be depleted when doing unclean disconnection of USB peripherals, and reaches the point where no transfer was possible until the next reboot/reload of the driver. Tested by putting a programmable USB mux on the port and randomly plugging/unpluging a USB HUB with USB mass-storage key, USB-audio and USB-ethernet dongle connected to its downstream ports, and also doing the disconnection early while the devices are still enumerating to get more URBs in-flight. After the patch, the devices are still enumerating after thousands of cycles, while the port was totally dead before.

2015-03-11usb: dwc2: pci: Add device mode to the dwc2-pci driverJohn Youn
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.

2015-02-04usb: dwc2: Fix a bug in reading the endpoint directions from reg.Roshan Pius
According to the DWC2 datasheet, the HWCFG1 register stores the configured endpoint directions for endpoints 0-15 in bit positions 0-31. ========================== Endpoint Direction (EpDir) This 32-bit field uses two bits per endpoint to determine the endpoint direction. Endpoint Bits [31:30]: Endpoint 15 direction Bits [29:28]: Endpoint 14 direction .... Bits [3:2]: Endpoint 1 direction Bits[1:0]: Endpoint 0 direction (always BIDIR) ========================== The DWC2 driver is currently interpreting the contents of the register as directions for endpoints 1-15 which leads to an error in determining the configured endpoint directions in the core because the first 2 bits determine the direction of endpoint 0 and not 1. This is based on testing/next branch in Felipe's git. Signed-off-by: Roshan Pius <rpius@chromium.org> Acked-by: John Youn <johnyoun@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
