2017-04-11usb: gadget: reword configuration choicesRomain Izard
As USB_CONFIGFS is not a part of the "USB Gadget Drivers" choice anymore, the name for the option and its attached description needs to be more descriptive. It appears one level higher in the configuration menu, and without the context provided by the comments for the choice entry, it needs to make sense on its own. Conversely, the "USB Gadget Drivers" entry now only introduces the legacy drivers, where one or more functions are combined in a single driver. As the configfs option can be used as a full-fledged alternative, rename the choice entry to show that it is not the only way to provice service as an USB gadget.

2017-04-11usb: gadget: legacy gadgets are optionalRomain Izard
With commit bc49d1d17dcf ("usb: gadget: don't couple configfs to legacy gadgets"),it is possible to build a modular kernel with both built-in configfs support and modular legacy gadget drivers. But when building a kernel without modules, it is also necessary to be able to build with configfs but without any legacy gadget driver. This was a possible configuration when the USB_CONFIGFS was a part of the choice options, but not anymore. Mark the choice for legacy gadget drivers as optional restores this.

2017-04-11usb: dwc3: gadget: Fix starting microframe for ISOCJohn Youn
The gadget wants to set the starting microframe for the first ISOC TRB to 4 microframes in the future, but it does so by multiplying the dep->interval. This only works if dep->interval = 1. For other intervals it will put it 4 *intervals* in the future which may be way too much. Fix so that it always adds just one interval or at least 4 microframes.

2017-04-11usb: dwc3: refactor gadget endpoint count calculationBryan O'Donoghue
- DWC_USB3_NUM indicates the number of Device mode single directional endpoints, including OUT and IN endpoint 0. - DWC_USB3_NUM_IN_EPS indicates the maximum number of Device mode IN endpoints active at any time, including control endpoint 0. It's possible to configure RTL such that DWC_USB3_NUM_EPS is equal to DWC_USB3_NUM_IN_EPS. dwc3-core calculates the number of OUT endpoints as DWC_USB3_NUM minus DWC_USB3_NUM_IN_EPS. If RTL has been configured with DWC_USB3_NUM_IN_EPS equal to DWC_USB3_NUM then dwc3-core will calculate the number of OUT endpoints as zero. For example a from dwc3_core_num_eps() shows: [ 1.565000] /usb0@f01d0000: found 8 IN and 0 OUT endpoints This patch refactors the endpoint calculation down to one variable dwc->num_eps taking care to maintain the current mapping of endpoints for fixed FPGA configurations as described in Table 4-7 of version 2.60a of the DWC USB3 databook. The endpoint mapping will then be EP-OUT, EP-IN etc, up to DWC_USB3_NUM. If DWC_USB3_NUM is odd then OUT will take the extra endpoint.

2017-04-11usb: dwc2: Make sure we disconnect the gadget stateJohn Stultz
I had seen some odd behavior with HiKey's usb-gadget interface that I finally seemed to have chased down. Basically every other time I plugged in the OTG port, the gadget interface would properly initialize. The other times, I'd get a big WARN_ON in dwc2_hsotg_init_fifo() about the fifo_map not being clear. Ends up if we don't disconnect the gadget state, the fifo-map doesn't get cleared properly, which causes WARN_ON messages and also results in the device not properly being setup as a gadget every other time the OTG port is connected. So this patch adds a call to dwc2_hsotg_disconnect() in the reset path so the state is properly cleared. With it, the gadget interface initializes properly on every plug in.

Currently usb3 port in fact includes two sub-ports, but it is not flexible for some cases, such as following one: usb3 port0 includes u2port0 and u3port0; usb2 port0 includes u2port1; If wants to support only HS, we can use u2port0 or u2port1, when select u2port0, u3port0 is not needed; If wants to support SS, we can compound u2port0 and u3port0, or u2port1 and u3port0, if select latter one, u2port0 is not needed. So it's more flexible to split usb3 port into two ones and also try best to save power by disabling unnecessary ports.

The Kconfig currently controlling compilation of this code is: drivers/phy/Kconfig:config PHY_EXYNOS_PCIE drivers/phy/Kconfig: bool "Exynos PCIe PHY driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

2017-04-08usb: xhci: bInterval quirk for TI TUSB73x0Roger Quadros
As per [1] issue #4, "The periodic EP scheduler always tries to schedule the EPs that have large intervals (interval equal to or greater than 128 microframes) into different microframes. So it maintains an internal counter and increments for each large interval EP added. When the counter is greater than 128, the scheduler rejects the new EP. So when the hub re-enumerated 128 times, it triggers this condition." This results in Bandwidth error when devices with periodic endpoints (ISO/INT) having bInterval > 7 are plugged and unplugged several times on a TUSB73x0 XHCI host. Workaround this issue by limiting the bInterval to 7 (i.e. interval to 6) for High-speed or faster periodic endpoints.
