* USB: s3c2410_udc: Add common implementation for GPIO controlled pullupsLars-Peter Clausen2011-03-071-9/+51
| | | | | | | | | | | Currently all boards using the s3c2410_udc driver use a GPIO to control the state of the pullup, as a result the same code is reimplemented in each board file. This patch adds support for using a GPIO to control the pullup state to the udc driver, so the boards can use a common implementation.

* usb/isp1760: Fix crash when unplugging bugArvid Brodin2011-03-071-4/+3
| | | | | | | | | | | | | This fixes a problem with my previous patch series where there's a great risk that the kernel will crash when unplugging interrupt devices from the USB port. These lines must have got missing when I rebased the patches from the older kernel I was working with to 2.6.37 and 2.6-next: This fixes a bug where the kernel may crash if you unplug a USB device that has active interrupt transfers.

* USB: move usbcore away from hcd->stateAlan Stern2011-03-072-21/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hcd->state variable is a disaster. It's not clearly owned by either usbcore or the host controller drivers, and they both change it from time to time, potentially stepping on each other's toes. It's not protected by any locks. And there's no mechanism to prevent it from going through an invalid transition. This patch (as1451) takes a first step toward fixing these problems. As it turns out, usbcore uses hcd->state for essentially only two things: checking whether the controller's root hub is running and checking whether the controller has died. Therefore the patch adds two new atomic bitflags to the hcd structure, to store these pieces of information. The new flags are used only by usbcore, and a private spinlock prevents invalid combinations (a dead controller's root hub cannot be running). The patch does not change the places where usbcore sets hcd->state, since HCDs may depend on them. Furthermore, there is one place in usb_hcd_irq() where usbcore still must use hcd->state: An HCD's interrupt handler can implicitly indicate that the controller died by setting hcd->state to HC_STATE_HALT. Nevertheless, the new code is a big improvement over the current code. The patch makes one other change. The hcd_bus_suspend() and hcd_bus_resume() routines now check first whether the host controller has died; if it has then they return immediately without calling the HCD's bus_suspend or bus_resume methods. This fixes the major problem reported in Bugzilla #29902: The system fails to suspend after a host controller dies during system resume.

| | | | | | | | | | | | | | | In wusb_cluster_id_get(), if no zero bits exist in wusb_cluster_id_table, find_first_zero_bit() returns CLUSTER_IDS. But it is impossible to detect that the bitmap is full because there is an off-by-one error in the return value check. It will cause unexpected memory access by setting bit out of wusb_cluster_id_table bitmap, and caller will get wrong cluster id.

* USB host: Move AMD PLL quirk to pci-quirks.cAndiry Xu2011-03-0110-229/+300
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the AMD PLL quirk code in OHCI/EHCI driver to pci-quirks.c, and exports the functions to be used by xHCI driver later. AMD PLL quirk disable the optional PM feature inside specific SB700/SB800/Hudson-2/3 platforms under the following conditions: 1. If an isochronous device is connected to OHCI/EHCI/xHCI port and is active; 2. Optional PM feature that powers down the internal Bus PLL when the link is in low power state is enabled. Without AMD PLL quirk, USB isochronous stream may stutter or have breaks occasionally, which greatly impair the performance of audio/video streams. Currently AMD PLL quirk is implemented in OHCI and EHCI driver, and will be added to xHCI driver too. They are doing similar things actually, so move the quirk code to pci-quirks.c, which has several advantages: 1. Remove duplicate defines and functions in OHCI/EHCI (and xHCI) driver and make them cleaner; 2. AMD chipset information will be probed only once and then stored. Currently they're probed during every OHCI/EHCI initialization, move the detect code to pci-quirks.c saves the repeat detect cost; 3. Build up synchronization among OHCI/EHCI/xHCI driver. In current code, every host controller enable/disable PLL only according to its own status, and may enable PLL while there is still isoc transfer on other HCs. Move the quirk to pci-quirks.c prevents this issue.

This is restricted to support offmode and retention only when device not connected.When device/cable connected with gadget driver loaded,configured to no idle/standby which will not allow the core transition to retention or off. There is no context save/restore done by hardware for musb in OMAP3 and OMAP4,driver has to take care of saving and restoring the context during offmode. Musb has a requirement of configuring sysconfig register to force idle/standby mode and set the ENFORCE bit in module STANDBY register for retention and offmode support. Runtime pm and hwmod frameworks will take care of configuring to force idle/standby when pm_runtime_put_sync is called and back to no idle/standby when pm_runeime_get_sync is called. Compile, boot tested and also tested the retention in the idle path on OMAP3630Zoom3. And tested the global suspend/resume with offmode enabled. Usb basic functionality tested on OMAP4430SDP. There is some problem with idle path offmode in mainline, I could not test with offmode. But I have tested this patch with resetting the controller in the idle path when wakeup from retention just to make sure that the context is lost, and restore path is working fine. Removed .suspend/.resume fnction pointers and functions because there is no need of having these functions as all required work is done at runtime in the driver. There is no need to call the runtime pm api with glue driver device as glue layer device is the parent of musb core device, when runtime apis are called for the child, parent device runtime functionality will be invoked. Design overview: pm_runtime_get_sync: When called with musb core device takes care of enabling the clock, calling runtime callback function of omap2430 glue layer, runtime call back of musb driver and configure the musb sysconfig to no idle/standby pm_runtime_put: Takes care of calling runtime callback function of omap2430 glue layer, runtime call back of musb driver, Configure the musb sysconfig to force idle/standby and disable the clock. During musb driver load: Call pm_runtime_get_sync. End of musb driver load: Call pm_runtime_put During gadget driver load: Call pm_runtime_get_sync, End of gadget driver load: Call pm_runtime_put if there is no device or cable is connected. During unload of the gadget driver:Call pm_runtime_get_sync if cable/device is not connected. End of the gadget driver unload : pm_runtime_put During unload of musb driver : Call pm_runtime_get_sync End of unload: Call pm_runtime_put On connect of usb cable/device -> transceiver notification(VBUS and ID-GND): pm_runtime_get_sync only if the gadget driver loaded.

* USB: serial drivers need to use larger bulk-in buffersAlan Stern2011-02-251-3/+2
| | | | | | | | | | | | | | | | | | | When a driver doesn't know how much data a device is going to send, the buffer size should be at least as big as the endpoint's maxpacket value. The serial drivers don't follow this rule; many of them request only 256-byte bulk-in buffers. As a result, they suffer overflow errors if a high-speed device wants to send a lot of data, because high-speed bulk endpoints are required to have a maxpacket size of 512. This patch (as1450) fixes the problem by using the driver's bulk_in_size value as a minimum, always allocating buffers no smaller than the endpoint's maxpacket size.

* ehci: Check individual port status registers on resumeMatthew Garrett2011-02-251-1/+22
| | | | | | | | | | | If a device plug/unplug is detected on an ATI SB700 USB controller in D3, it appears to set the port status register but not the controller status register. As a result we'll fail to detect the plug event. Check the port status register on resume as well in order to catch this case.
