* USB: serial: option: Apply OPTION_BLACKLIST_SENDSETUP also for ZTE MF626Herton Ronaldo Krzesinski2011-03-09
| | | | | | | | | | | | | On https://bugs.launchpad.net/ubuntu/+source/linux/+bug/636091, one of the cases reported is a big timeout on option_send_setup, which causes some side effects as tty_lock is held. Looks like some of ZTE MF626 devices also don't like the RTS/DTR setting in option_send_setup, like with 4G XS Stick W14. The reporter confirms which this it solves the long freezes in his system.

* USB OTG Langwell: use simple IPC command to control VBus power.Hao Wu2011-03-09
| | | | | | | | | | | | | | | Direct access to PMIC register is not safe and will impact battery charging. New IPC command supported in SCU FW for VBus power control. USB OTG driver will switch to such commands instead of direct access to PMIC register for safety and SCU FW will handle the actual work after got the request(IPC command). Due to this change, usb driver should wait more time for sync OTGSC with USBCFG by SCU. Update wait time from 2ms to 5ms.

* arm: omap4: 4430sdp: drop ehci supportAnand Gadiyar2011-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most revisions of the OMAP4 Blaze/SDP platform do not have the EHCI signals routed by default. The pads are routed for the alternate HSI functionality instead, and explicit board modifications are needed to route the signals to the USB PHY on the board. Also, turning on the PHY connected to the EHCI port causes a board reboot during bootup due to an unintended short on the rails - this affects many initial revisions of the board, and needs a minor board mod to fix (or as a workaround, one should not attempt to power on the USB PHY). Given that these boards need explicit board mods to even get EHCI working (separate from the accidental short above), we should not attempt to enable EHCI by default. So drop the EHCI support from the board files for the Blaze/SDP platforms.

* USB: move usbcore away from hcd->stateAlan Stern2011-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* USB host: Move AMD PLL quirk to pci-quirks.cAndiry Xu2011-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/isp1760: Remove redundant variables and definesArvid Brodin2011-02-28
| | | | | | | | Removes the redundant hw_next list pointer from struct isp1760_qtd, removes some unused #defines, removes redundant "urb" member from struct inter_packet_info. Signed-off-by: Arvid Brodin <arvid.brodin@enea.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* usb/isp1760: Move to native-endian ptdsArvid Brodin2011-02-28
| | | | | | | | | | | This helps users with platform-bus-connected isp176xs, big-endian cpu, and missing byteswapping on the data bus. It does so by collecting all SW byteswaps in one place and also fixes a bug with non-32-bit io transfers on this hardware, where payload has to be byteswapped instead of ptds.
