git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB dwc3 patches from Felipe: "usb: dwc3: patches for v3.8 We can finaly drop HAVE_CLK dependency from exynos glue layer now that clk API provides no-op stubs when it's not linked into the kernel. We're also switching over event buffer allocation to devm_kzalloc() and moving the allocation out of dwc3_core_init() so that can be re-used when implementing PM support for v3.9. After the introduction of PLATFORM_DEVID_AUTO, we can also drop the homebrew platform device ID handling we had on dwc3 core and let driver core take care of that for us. Exynos glue layer learns about DeviceTree and drops platform_data support completely."

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB musb merge from Felipe: "usb: musb: patches for v3.8 merge window We have here the usual set of cleanups for the MUSB driver; a big set of patches converting platform_device_del() and platform_device_put() into platform_device_unregister(). Another big set was applied converting to module_platform_driver() macro in order to reduce some boilerplate code from all glue layers. Other than that, we had a series fixing one known silicon errata where we couldn't read a few registers. In order to fix that we're now using shadow variables for reads and only writing to the registers which are known to break functionality when read."

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into USB-next Pull USB phy patches from Felipe: "usb: phy: patches for v3.8 merge window Not too many patches this time. First two patches are only cleanups where one of them switches over to module_platform_driver macro and the second removes inclusion of <mach/iomap.h> and is part of a bigger set of include cleanups from the Tegra folks. The only substantial change here is the addition of a driver for Renesas' R-Car USB Phy controller."
2012-11-09Revert "usb: musb: dsps: remove explicit NOP device creation"Afzal Mohammed1-1/+2
This reverts commit d8c3ef256f88b7c6ecd673d03073b5645be9c5e4. Above mentioned change was made along with multi usb phy change and adding DT support for nop transceiver. But other two changes did not make it to mainline. This in effect makes dsps musb wrapper unusable even for single instance. Hence revert it so that at least single instance can be supported.

2012-11-06usb: musb: remove generic_interruptPhilippe De Swert4-33/+46
This patch is based on the discussion of a previous patch to fix an issue where the omap2430 musb driver is not working for N9/N950. Moving all the interrupt handling to the devices. Avoids inclusion of generic interrupt and breakage due to sometimes misleading CONFIG options. This makes sure usb always works if on of the subdrivers is chosen. Tested on Nokia N9/N950. Partially clean up CONFIG_SOC_OMAP3430 which is not necessary in the cases where I removed it. Also helps with the removal work of those options that Tony Lindgren predicted would happen at some point.

2012-11-06usb: musb: dsps: control module handling (quirk)Santhapuri, Damodar1-0/+69
am335x uses nop transceiver driver and need to enable builtin phy by writing into usb_ctrl register available in system control module register space. This is being added at musb glue driver layer until a separate system control module driver is available. Proper solution is to make use of control module driver, but it is not expected to be ready soon. Other options available are providing control module register space as memory resource via DT or using omap hwmod. DT approach has been rejected by Rob Herring, while resources are being moved from hwmod to DT. And both of the above approaches require that control module registers be configured in wrapper itself requring a quirk in driver as well as DT or hwmod. Here another option is used, providing driver with control module register physical address. Even though this a hack, there is no other option left till control module driver is ready. As of now only am335x is using dsps wrapper, and so driver is made aware of am335x control module physical address. Please note that this is a temporary arrangment till omap control module driver is available.

2012-11-06usb: musb: dsps: reduce musb instance to oneAfzal Mohammed1-1/+1
Currently multiple phy's of the same type are not supported, hence reduce musb instances to one. This helps in supporting at least one instance of musb, rather than having none. Even without this, it was observed that both instances were working (by luck), but this holds good iff wrapper is part of Image. And it is not correct for both controller's to be associated with same phy, here it was working because phy is a nop one. And having wrapper as a module and rmmod'ing would crash. This can be reverted once multi phy support for same type is available and driver is enhanced to make use of it.

2012-11-02USB: EHCI: fix build error by making ChipIdea host a normal EHCI driverAlan Stern3-54/+9
This patch (as1627) splits the ehci-hcd core code, which has become a separate library module, out from the ChipIdea host driver. Instead of #include-ing ehci-hcd.c directly, the ChipIdea module will now use the ehci-hcd library in a normal fashion. This fixes a build error caused by commit 3e0232039967d7a1a06c013d097458b4d5892af1 (USB: EHCI: prepare to make ehci-hcd a library module); I had forgotten about the unorthodox way the ChipIdea driver uses the ehci-hcd code.

2012-11-02USB: ohci-exynos: initialize registers pointer earlierVincent Palatin1-4/+6
In the former code, we have a race condition between the first interrupt and the regs field initilization in the usb_hcd structure. If the OHCI irq fires before hcd->regs is set, we are getting a null pointer dereference in ohci_irq. When calling usb_add_hcd(), it first executes the reset() callback, then enables the ohci interrupt, and finally executes the start() callback. So moving the ohci_init() call which actually initializes the reg field from start() to reset() should remove the race. Tested by enabling the external HSIC hub in the bootloader on an exynos5 machine and booting. With the former code, this triggers an early interrupt about 50% of the boots and a subsequent kernel panic in ohci_irq when trying to access the registers.

This patch (as1624) prepares ehci-hcd for being split up into a core library and separate platform driver modules. A generic ehci_hc_driver structure is created, containing all the "standard" values, and a new mechanism is added whereby a driver module can specify a set of overrides to those values. In addition the ehci_setup(), ehci_suspend(), and ehci_resume() routines need to be EXPORTed for use by the drivers. As a side effect of this change, a few routines no longer need to be marked __maybe_unused.

This patch (as1623) removes the ehci_port_power() routine and all the places that call it. There's no reason for ehci-hcd to change the port power settings; the hub driver takes care of all that stuff. There is one exception: When the controller is resumed from hibernation or following a loss of power, the ports that are supposed to be handed over to a companion controller must be powered on first. Otherwise the handover won't work. This process is not visible to the hub driver, so it has to be handled in ehci-hcd.

2012-10-31USB: EHCI: remove unused Link Power Management codeAlan Stern7-239/+1
This patch (as1622) removes the USB-2.1 Link Power Management code from the ehci-hcd driver. This code was never integrated with usbcore, it is full of bugs, and it was not getting used by anybody. However, the debugging code for dumping the LPM-related fields in the EHCI registers is left in place. In theory it might be useful to see these values, even though we don't use them. This essentially amounts to a partial revert of commit aa4d8342988d0c1a79ff19b2ede1e81dfbb16ea5 (USB: EHCI: EHCI 1.1 addendum: preparation) and an almost full revert of commit 48f24970144479c29b8cee6d2e1dbedf6dcf9cfb (USB: EHCI: EHCI 1.1 addendum: Basic LPM feature support) plus its follow-ons.

This patch (as1621) removes the limit on the number of loops allowed in hub_tt_work().

2012-10-31USB: fix build with XEN and EARLY_PRINTK_DBGP enabled but USB_SUPPORT disabledJan Beulich1-6/+9
Since there's no possible caller of dbgp_external_startup() and dbgp_reset_prep() when !USB_EHCI_HCD, there's no point in building and exporting these functions in that case. This eliminates a build error under the conditions listed in the subject, introduced with the merge f1c6872e4980bc4078cfaead05f892b3d78dea64.
