* xhci: Remove references to HC_STATE_RUNNING.Sarah Sharp2011-03-13
| | | | | | | | | | | The USB core will set hcd->state to HC_STATE_RUNNING before calling xhci_run, so there's no point in setting it twice. The USB core also doesn't pay attention to HC_STATE_RUNNING on the resume path anymore; it uses HCD_RH_RUNNING(), which looks at hcd->flags & (1U << HCD_FLAG_RH_RUNNING. Therefore, it's safe to remove the state set in xhci_bus_resume(). Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
* usb: Initialize hcd->state roothubs.Sarah Sharp2011-03-13
| | | | | | | | | | | | | | We would like to allow host controller drivers to stop using hcd->state. Unfortunately, some host controller drivers use hcd->state as an implicit way of telling the core that a controller has died. The roothub registration functions must assume the host died if hcd->state equals HC_STATE_HALT. To facilitate drivers that don't want to set hcd->state to HC_STATE_RUNNING in their initialization routines, we set the state to running before calling the host controller's start function.

* xhci: Remove references to HC_STATE_HALT.Sarah Sharp2011-03-13
| | | | | | | | | The xHCI driver doesn't ever test hcd->state for HC_STATE_HALT. The USB core recently stopped using it internally, so there's no point in setting it in the driver. We still need to set HC_STATE_RUNNING in order to make it past the USB core's hcd->state check in register_roothub(). Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
* xHCI: prolong host controller halt time limitAndiry Xu2011-03-13
| | | | | | | | | | | | | xHCI 1.0 spec specifies the xHC shall halt within 16ms after software clears Run/Stop bit. In xHCI 0.96 spec the time limit is 16 microframes (2ms), it's too short and often cause dmesg shows "Host controller not halted, aborting reset." message when rmmod xhci-hcd. Modify the time limit to comply with xHCI 1.0 specification and prevents the warning message showing when remove xhci-hcd.

* xhci: Rename variables and reduce register reads.Sarah Sharp2011-03-13
| | | | | | | | | | | The xhci_bus_suspend() and xhci_bus_resume() functions are a bit hard to read, because they have an ambiguously named variable "port". Rename it to "port_index". Introduce a new temporary variable, "max_ports" that holds the maximum number of roothub ports the host controller supports. This will reduce the number of register reads, and make it easy to change the maximum number of ports when there are two roothubs. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
* xhci: Rework port suspend structures for limited ports.Sarah Sharp2011-03-13
| | | | | | | | | | | | | | | | | | | | | | The USB core only allows up to 31 (USB_MAXCHILDREN) ports under a roothub. The xHCI driver keeps track of which ports are suspended, which ports have a suspend change bit set, and what time the port will be done resuming. It keeps track of the first two by setting a bit in a u32 variable, suspended_ports or port_c_suspend. The xHCI driver currently assumes we can have up to 256 ports under a roothub, so it allocates an array of 8 u32 variables for both suspended_ports and port_c_suspend. It also allocates a 256-element array to keep track of when the ports will be done resuming. Since we can only have 31 roothub ports, we only need to use one u32 for each of the suspend state and change variables. We simplify the bit math that's trying to index into those arrays and set the correct bit, if we assume wIndex never exceeds 30. (wIndex is zero-based after it's decremented from the value passed in from the USB core.) Finally, we change the resume_done array to only hold 31 elements.

* USB: Remove bitmap #define from hcd.hSarah Sharp2011-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using a #define to redefine a common variable name is a bad thing, especially when the #define is in a header. include/linux/usb/hcd.h redefined bitmap to DeviceRemovable to avoid typing a long field in the hub descriptor. This has unintended side effects for files like drivers/usb/core/devio.c that include that file, since another header included after hcd.h has different variables named bitmap. Remove the bitmap #define and replace instances of it in the host controller code. Cleanup the spaces around function calls and square brackets while we're at it.

* usb: Always return 0 or -EBUSY to the runtime PM core.Sarah Sharp2011-03-13
| | | | | | | | | | | | | | | | The PM core reacts badly when the return code from usb_runtime_suspend() is not 0, -EAGAIN, or -EBUSY. The PM core regards this as a fatal error, and refuses to run anymore PM helper functions. In particular, usbfs_open() and other usbfs functions will fail because the PM core will return an error code when usb_autoresume_device() is called. This causes libusb and/or lsusb to either hang or segfault. If a USB device cannot suspend for some reason (e.g. a hub doesn't report it has remote wakeup capabilities), we still want lsusb and other userspace programs to work. So return -EBUSY, which will fill people's log files with failed tries, but will ensure userspace still works. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

* usb: host: Add EHCI driver for NVIDIA Tegra SoCsBenoit Goby2011-03-11
| | | | | | | | | | | | | | | The Tegra 2 SoC has 3 EHCI compatible USB controllers. This patch adds the necessary glue to allow the ehci-hcd driver to work on Tegra 2 SoCs. The platform data is used to configure board-specific phy settings and to configure the operating mode, as one of the ports may be used as a otg port. For additional power saving, the driver supports powering down the phy on bus suspend when it is used, for example, to connect an internal device that use an out-of-band remote wakeup mechanism (e.g. a gpio).

* 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.

| | | | | | | | | now that we have names on all memory bases, we can switch to use platform_get_resource_byname() which will make it simpler when we move to a setup where OHCI and EHCI on OMAP play well together. Signed-off-by: Felipe Balbi <balbi@ti.com>
* arm: omap: usb: host: add names to resourcesFelipe Balbi2011-03-01
| | | | | | | | add names to EHCI and OHCI resources. That will help us identify the resource correctly when moving to a setup where OHCI and EHCI play well together. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: ehci: omap: add support for TLL mode on OMAP4Anand Gadiyar2011-03-01
| | | | | | | | | | | | | | The EHCI controller in OMAP4 supports a transceiver-less link mode (TLL mode), similar to the one in OMAP3. On the OMAP4 however, there are an additional set of clocks that need to be turned on to get this working. Request and configure these for each port if that port is connected in TLL mode.

* usb: musb: OMAP3xxx: Fix device detection in otg & host modeHema HK2011-03-01
| | | | | | | | | | | | | | | In OMAP3xxx with OTG mode or host only mode, When the device is inserted after the gadget driver loading the enumeration was not through. This is because the mentor controller will start sensing the ID PIN only after setting the session bit. So after ID-GND, need to set the session bit for mentor to get it configured as A device. This is a fix to set the session bit again in ID_GND notification handler. Tested with OMAP3630Zoom3 platform. Signed-off-by: Hema HK <hemahk@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
