* uwb: add error messages when reservation establish failsThomas Pugliese2014-05-272-3/+15

* uwb: fix channel change failureThomas Pugliese2014-05-271-1/+6
| | | | | | | | | | | | | | Make the transition to the UWB_RSV_STATE_NONE state synchronous so that there is not a race between uwb_rsv_terminate and uwb_rsv_establish. uwb_rsv_terminate would set the rsv->state to UWB_RSV_STATE_NONE but did not release the stream resource until a 320ms timeout had expired. If a user called uwb_rsv_establish during that time, it could fail to establish the reservation because no stream resources were available. This patch removes the timer from the uwb_rsv_terminate process since it is not needed when transitioning to UWB_RSV_STATE_NONE.

* usb: host: ohci-exynos: Use devm_ioremap_resource instead of devm_ioremapVivek Gautam2014-05-271-4/+3
| | | | | | | | | | | | Using devm_ioremap_resource() API should actually be preferred over devm_ioremap(), since the former request the mem region first and then gives back the ioremap'ed memory pointer. devm_ioremap_resource() calls request_mem_region(), therby preventing other drivers to make any overlapping call to the same region.

| | | | | | | | | | | | | | | | | | | | | | The field PLLDIVVALUE of register PHY_CTRL_1 selects the reference clock source for the PHY: 00 = sysclock uses 19.2 MHz 01 = sysclock uses 24 MHz 10 = sysclock uses 26 MHz 11 = sysclock uses 27 MHz The reset value for this field is 10 according to the reference manual, and even though this reset value works for mx53, it does not work for mx51. So instead of relying on the reset value for the PLLDIVVALUE field, explicitly set it to 01 so that a 24MHz clock can be selected for the PHY and allowing both mx51 and mx53 to have USB OTG port functional. Succesfully tested 'g_ether' on a imx51-babbage and on a imx53-qsb boards.

Hosts which expect the "OS Descriptors" ask only for configurations @ index 0, but linux-based USB devices can provide more than one configuration. This patch adds marking one of gadget's configurations the configuration to be reported at index 0, regardless of the actual sequence of usb_add_config invocations used for adding the configurations. The configuration is selected by creating a symbolic link pointing to it from the "os_desc" directory located at the top of a gadget's directory hierarchy. One kind of "OS Descriptors" are "Extended Compatibility Descriptors", which need to be specified per interface. This patch adds interface.<n> directory in function's configfs directory to represent each interface defined by the function. Each interface's directory contains two attributes: "compatible_id" and "sub_compatible_id", which represent 8-byte strings to be reported to the host as the "Compatible ID" and "Sub Compatible ID".

Microsoft hereby grants to You a nonexclusive, royalty-free, nontransferable, worldwide license under Microsoft’s patents embodied solely within the Specification and that are owned or licensable by Microsoft to make, use, import, offer to sell, sell and distribute directly or indirectly to Your Licensees Your Implementation. You may sublicense this patent license to Your Licensees under the same terms and conditions." The said extension is maintained by Microsoft for Microsoft. Yet it is fairly common for various devices to use it, and a popular proprietary operating system expects devices to provide "OS descriptors", so Linux-based USB gadgets whishing to be able to talk to a variety of operating systems should be able to provide the "OS descriptors". This patch adds optional support for gadgets whishing to expose the so called "OS Feature Descriptors", that is "Extended Compatibility ID" and "Extended Properties". Hosts which do request "OS descriptors" from gadgets do so during the enumeration phase and before the configuration is set with SET_CONFIGURATION. What is more, those hosts never ask for configurations at indices other than 0. Therefore, gadgets whishing to provide "OS descriptors" must designate one configuration to be used with this kind of hosts - this is what os_desc_config is added for in struct usb_composite_dev. There is an additional advantage to it: if a gadget provides "OS descriptors" and designates one configuration to be used with such non-USB-compliant hosts it can invoke "usb_add_config" in any order because the designated configuration will be reported to be at index 0 anyway. This patch also adds handling vendor-specific requests addressed at device or interface and related to handling "OS descriptors".

| * usb: gadget: OS String supportAndrzej Pietrasiewicz2014-05-142-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a custom (non-USB IF) extension to the USB standard: http://msdn.microsoft.com/library/windows/hardware/gg463182 They grant permission to use the specification - there is "Microsoft OS Descriptor Specification License Agreement" under the link mentioned above, and its Section 2 "Grant of License", letter (b) reads: "Patent license. Microsoft hereby grants to You a nonexclusive, royalty-free, nontransferable, worldwide license under Microsoft’s patents embodied solely within the Specification and that are owned or licensable by Microsoft to make, use, import, offer to sell, sell and distribute directly or indirectly to Your Licensees Your Implementation. You may sublicense this patent license to Your Licensees under the same terms and conditions." The said extension is maintained by Microsoft for Microsoft. Yet it is fairly common for various devices to use it, and a popular proprietary operating system expects devices to provide "OS descriptors", so Linux-based USB gadgets whishing to be able to talk to a variety of operating systems should be able to provide the "OS descriptors". This patch adds optional support for gadgets whishing to expose the so called "OS String" under index 0xEE of language 0. The contents of the string is generated based on the qw_sign array and b_vendor_code. Interested gadgets need to set the cdev->use_os_string flag, fill cdev->qw_sign with appropriate values and fill cdev->b_vendor_code with a value of their choice. This patch does not however implement responding to any vendor-specific USB requests.

| * usb: gadget: FunctionFS: share VLA macros with all usb gadget filesAndrzej Pietrasiewicz2014-05-142-26/+27
| | | | | | | | | | | | | | | | | | | | | | Variable Length Array macros allow portable (compilable with both gcc and clang) way of allocating a number of structures using a single memory chunk. They can be useful for files other than f_fs.c, so move them to a header file.

| * usb: phy: msm: change devm_ioremap() to devm_ioremap_resource()Dan Carpenter2014-05-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | There are several issues here: 1) platform_get_resource() can return NULL and that wasn't handled. 2) We should request the memory before we remap it, and devm_ioremap_resource() does that. 3) devm_ioremap() returns a NULL but we were checking for IS_ERR().

| * usb: phy: msm: reset controller is mandatory nowArnd Bergmann2014-05-142-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit a27345434134 "usb: phy: msm: Use reset framework for LINK and PHY resets" introduced a mandatory call to reset_control_get into the msm usb phy driver, which means we have to add a Kconfig dependency on the API to avoid this build error: phy/phy-msm-usb.c: In function 'msm_otg_read_dt': phy/phy-msm-usb.c:1461:2: error: implicit declaration of function 'devm_reset_control_get' [-Werror=implicit-function-declaration] motg->link_rst = devm_reset_control_get(&pdev->dev, "link"); ^ Since the usb-ehci-msm driver currently selects the OTG driver, we could still get a broken dependency here. To solve that, this patch also removes the 'select', which turns out to be unnecessary. Reviewed-by: Ivan T.

| * usb: gadget: s3c2410_udc: don't use pr_debug return valueArnd Bergmann2014-05-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pr_debug() may be defined as "do { } while (0)" in some configurations, which means one cannot rely on the return value to be available. In the dprintk function in this driver, we can work around the resulting build error trivially by returning the length that this function already knows and ignoring the return value of pr_debug.
