* usb: dwc3: core: make dwc3_set_mode() work properlyRoger Quadros2017-04-113-38/+80
| | | | | | | | | | | | We can't have both Host and Peripheral roles active at the same time because of one detail on DWC3: it shares the same memory area for both Host and Peripheral registers. When swapping roles we must reinitialize the new role every time. Let's make sure this works for our debugfs interface.

* usb: gadget: mv_u3d: fix error handling in mv_u3d_probe()Alexey Khoroshilov2017-04-111-6/+9
| | | | | | | | | | | | | | There are several inconsistencies in the error handling code. 1. If clk_get() fails, it goes to clk_put(). 2. If pdata->phy_init() fails, it does not disable u3d->clk. 3. In case of failure after stopping u3d, it does pdata->phy_deinit() and clk_disable(u3d->clk) twice. 4. It ignores failures in clk_enable().

* usb: gadget: udc: amd5536: split core and PCI layerRaviteja Garimella2017-04-115-215/+297
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch splits the amd5536udc driver into two -- one that does pci device registration and the other file that does the rest of the driver tasks like the gadget/ep ops etc for Synopsys UDC. This way of splitting helps in exporting core driver symbols which can be used by any other platform/pci driver that is written for the same Synopsys USB device controller. The current patch also includes a change in the Kconfig and Makefile. A new config option USB_SNP_CORE will be selected automatically when any one of the platform or pci driver for the same UDC is selected. Main changes: - amd5536udc_pci.c: PCI device registration is moved to this file. - amd5536udc.c: This file does rest of the core UDC fucntionality. 9 symbols are exported so as to be used by amd5536udc_pci.c. Module parameter definitions are moved to header file. - amd5536udc.h: Function declarations, module parameters definitions and few common header file includes are added to this file - Kconfig: New USB_SNP_CORE option is added which will be auto selected when any pci or platform driver config option for the UDC is chosen. - Makefile: Compiles the core and pci files separately.

* usb: gadget: udc: renesas_usb3: add support for usb role swapYoshihiro Shimoda2017-04-112-0/+71
| | | | | | | | | | | | | | | | | | | | | This patch adds support for usb role swap via sysfs "role". For example: 1) Connect a usb cable using 2 Salvator-X boards. - For A-Device, the cable is connected to CN11 (USB3.0 ch0). - For B-Device, the cable is connected to CN9 (USB2.0 ch0). 2) On A-Device, you input the following command: # echo peripheral > /sys/devices/platform/soc/ee020000.usb/role 3) On B-Device, you input the following command: # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Then, the A-Device acts as a peripheral and the B-Device acts as a host. Please note that A-Device must input the following command if you want the board to act as a host again. # echo host > /sys/devices/platform/soc/ee020000.usb/role Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

* usb: gadget: f_fs: simplify ffs_dev name handlingMichal Nazarewicz2017-04-112-64/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ffs_dev::name can be either allocated by the client of the ffs_dev structure or by the f_fs.c core itself. The former is used by g_ffs while the latter happens with configfs. Historically, g_ffs did not need to allocate separate buffer for the name so what is now f_fs.c core never cared about freeing that space. With configfs the name needs to be copied since the memory is not guaranteed to be availeble after ffs_set_inst_name finishes. The complication is therefore here to avoid allocations in the g_ffs case but it complicates the code inproportinally to benefits it provides. In particular, g_ffs is considered ‘legacy’ so optimising for its sake is unlikely to be worth the effort. With that observation in mind, simplify the code by unifying the code paths in g_ffs and configfs paths. Furthermore, instead of allocating a new buffer for the name, simply embed it in the ffs_dev structure. This further makes the memory management less convoluted and error-prone. The configfs interface for functionfs imposed a limit of 40 characters for the name so this results in a 41-byte buffer added to the structure. (For short names this may lead to wasted memory but the actual amount is not immediately obvious and depends on pointer size and which slab buckets the structure and name would fall into).

| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* usb: dwc2: Make sure we disconnect the gadget stateJohn Stultz2017-04-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* usb: gadget: mv_udc: clarify a switch with an implicit fall-throughMichal Nazarewicz2017-03-271-7/+6
| | | | | | | | | | | | Rearrange statements in mv_ep_enable function so that it’s obvious what the switch does and how zlt, ios and mult variables are initialised. Most notably, this gets rid of an implicit fall-through so people don’t have to wonder whether it was intenional or not. Addresses-Coverity-ID: 201385 Reported-by: Gustavo A. R.

* usb: dwc3: make sure UX_EXIT_PX is clearedFelipe Balbi2017-03-272-0/+7
| | | | | | | | | | This bit is only supposed to be used with known buggy PHYs, however some platforms might erroneously set it. In order to avoid it, let's make sure this bit is always cleared. If some PHY needs this, we will need to add a quirk flag. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
