2013-06-11usb: chipidea: fix id change handlingAlexander Shishkin1-1/+2
Re-enable chipidea irq even if there's no role changing to do. This is a problem since b183c19f ("USB: chipidea: re-order irq handling to avoid unhandled irqs"); when it manifests, chipidea irq gets disabled for good.

Since usb phy code does return ERR_PTR() values, make sure that we don't end up dereferencing them. This is a problem, for example, on platforms that don't register a phy for chipidea since b7fa5c2a ("usb: phy: return -ENXIO when PHY layer isn't enabled").

2013-05-16USB: set device dma_mask without reference to global dataStephen Warren1-11/+4
Many USB host drivers contain code such as: if (!pdev->dev.dma_mask) pdev->dev.dma_mask = &tegra_ehci_dma_mask; ... where tegra_ehci_dma_mask is a global. I suspect this code originated in commit 4a53f4e "USB: ehci-tegra: add probing through device tree" and was simply copied everywhere else. This works fine when the code is built-in, but can cause a crash when the code is in a module. The first module load sets up the dma_mask pointer, but if the module is removed and re-inserted, the value is now non-NULL, and hence is not updated to point at the new location, and hence points at a stale location within the previous module load address, which in turn causes a crash if the pointer is de-referenced. The simplest way of solving this seems to be to copy the code from ehci-platform.c, which uses the coherent_dma_mask as the target for the dma_mask pointer.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.10 merge window Here is the big Gadget & PHY pull request. Many of us have been really busy lately getting multiple drivers to a better position. Since this pull request is so large, I will divide it in sections so it's easier to grasp what's included. - cleanups: . UDC drivers no longer touch gadget->dev, that's now udc-core responsibility . Many more UDC drivers converted to usb_gadget_map/unmap_request() . UDC drivers no longer initialize DMA-related fields from gadget's device structure . UDC drivers don't touch gadget.dev.driver directly . UDC drivers don't assign gadget.dev.release directly . Removal of some unused DMA_ADDR_INVALID . Introduction of CONFIG_USB_PHY . All phy drivers have been moved to drivers/usb/phy and renamed to a common naming scheme . Fix PHY layer so it never returns a NULL pointer, also fix all callers to avoid using IS_ERR_OR_NULL() . Sparse fixes all over the place . drivers/usb/otg/ has been deleted . Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock usage - new features: . UDC core now provides a generic way for tracking and reporting UDC's state (not attached, resuming, suspended, addressed, default, etc) . twl4030-usb learned that it shouldn't be enabled during init . Full DT support for DWC3 has been implemented . ab8500-usb learned about pinctrl framework . nop PHY learned about DeviceTree and regulators . DWC3 learned about suspend/resume . DWC3 can now be compiled in host-only and gadget-only (as well as DRD) configurations . UVC now enables streaming endpoint based on negotiated speed . isp1301 now implements the PHY API properly . configfs-based interface for gadget drivers which will lead to the removal of all code which just combines functions together to build functional gadget drivers. . f_serial and f_obex were converted to new configfs interface while maintaining old interface around. - non-critical fixes: . UVC gadget driver got fixes for Endpoint usage and stream calculation . ab8500-usb fixed unbalanced clock and regulator API usage . twl4030-usb got a fix for when OMAP3 is booted with cable connected . fusb300_udc got a fix for DMA usage . UVC got fixes for two assertions of the USB Video Class Compliance specification revision 1.1 . build warning issues caused by recent addition of __must_check to regulator API These are all changes which deserve a mention, all other changes are related to these one or minor spelling fixes and other similar tasks.

2013-04-05usb: chipidea: udc: fix memory access of shared memory on armv5 machinesMichael Grzeschik2-2/+4
The udc uses an shared dma memory space between hard and software. This memory layout is described in ci13xxx_qh and ci13xxx_td which are marked with the attribute ((packed)). The compiler currently does not know about the alignment of the memory layout, and will create strb and ldrb operations. The Datasheet of the synopsys core describes, that some operations on the mapped memory need to be atomic double word operations. I.e. the next pointer addressing in the qhead, as otherwise the hardware will read wrong data and totally stuck. This is also possible while working with the current active td queue, and preparing the td->ptr.next in software while the hardware is still working with the current active td which is supposed to be changed: writeb(0xde, &td->ptr.next + 0x0); /* strb */ writeb(0xad, &td->ptr.next + 0x1); /* strb */ <----- hardware reads value of td->ptr.next and get stuck! writeb(0xbe, &td->ptr.next + 0x2); /* strb */ writeb(0xef, &td->ptr.next + 0x3); /* strb */ This appeares on armv5 machines where the hardware does not support unaligned 32bit operations. This patch adds the attribute ((aligned(4))) to the structures to tell the compiler to use 32bit operations. It also adds an wmb() for the prepared TD data before it gets enqueued into the qhead.

2013-02-19locking: Various static lock initializer fixesThomas Gleixner1-1/+1
The static lock initializers want to be fed the proper name of the lock and not some random string. In mainline random strings are obfuscating the readability of debug output, but for RT they prevent the spinlock substitution. Fix it up. Signed-off-by: Thomas Gleixner <[email protected]>

2013-01-22usb: Convert to devm_ioremap_resource()Thierry Reding1-3/+3
Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.
