From Stephen Warren: ARM: tegra: implement common DMA and resets DT bindings This series converts the Tegra DTs and drivers to use the common/ standard DMA and reset bindings, rather than custom bindings. It also adds complete documentation for the Tegra clock bindings without actually changing any binding definitions. This conversion relies on a few sets of patches in branches from outside the Tegra tree: 1) A patch to add an DMA channel request API which allows deferred probe to be implemented. 2) A patch to implement a common part of the of_xlate function for DMA controllers. 3) Some ASoC patches (which in turn rely on (1) above), which support deferred probe during DMA channel allocation. 4) The Tegra clock driver changes for 3.14. Consequently, this branch is based on a merge of all of those external branches. In turn, this branch is or will be pulled into a few places that either rely on features introduced here, or would otherwise conflict with the patches: a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid conflicts. b) The DRM tree, which introduces new code that relies on the reset controller framework introduced in this branch, and to avoid conflicts. * tag 'tegra-for-3.14-dmas-resets-rework' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: (30 commits) spi: tegra: checking for ERR_PTR instead of NULL ASoC: tegra: update module reset list for Tegra124 clk: tegra: remove bogus PCIE_XCLK clk: tegra: remove legacy reset APIs ARM: tegra: remove legacy DMA entries from DT ARM: tegra: remove legacy clock entries from DT USB: EHCI: tegra: use reset framework Input: tegra-kbc - use reset framework serial: tegra: convert to standard DMA DT bindings serial: tegra: use reset framework spi: tegra: convert to standard DMA DT bindings spi: tegra: use reset framework staging: nvec: use reset framework i2c: tegra: use reset framework ASoC: tegra: convert to standard DMA DT bindings ASoC: tegra: allocate AHUB FIFO during probe() not startup() ASoC: tegra: call pm_runtime APIs around register accesses ASoC: tegra: use reset framework dma: tegra: register as an OF DMA controller dma: tegra: use reset framework ...

Sarah writes: xhci: Cleanups, non-urgent fixes for 3.14. Happy Holidays, Greg! Here's four patches to be queued to usb-next for 3.14. One adds a module parameter to the xHCI driver to allow users to enable xHCI quirks without recompiling their kernel, which you've already said is fine. The second patch is a bug fix for new usbtest code that's only in usb-next. The third patch is simple cleanup. The last patch is a non-urgent bug fix for xHCI platform devices. The bug has been in the code since 3.9. You've been asking me to hold off on non-urgent bug fixes after -rc4/-rc5, so it can go into usb-next, and be backported to stable once 3.14 is out. These have all been tested over the past week. I did run across one oops, but it turned out to be a bug in 3.12, and therefore not related to any of these patches. Please queue these for usb-next and 3.14. Thanks, Sarah Sharp

If CONFIG_PCI is enabled, make sure xhci_cleanup_msix() doesn't try to free a bogus PCI IRQ or dereference an invalid pci_dev when the xHCI device is actually a platform_device.

2013-12-10usb: xhci: change enumeration scheme to 'new scheme' by defaultDan Williams5-8/+30
Change the default enumeration scheme for xhci attached non-SuperSpeed devices from: Reset SetAddress [xhci address-device BSR = 0] GetDescriptor(8) GetDescriptor(18) ...to: Reset [xhci address-device BSR = 1] GetDescriptor(64) Reset SetAddress [xhci address-device BSR = 0] GetDescriptor(18) ...as some devices misbehave when encountering a SetAddress command prior to GetDescriptor. There are known legacy devices that require this scheme, but testing has found at least one USB3 device that fails enumeration when presented with this ordering. For now, follow the ehci case and enable 'new scheme' by default for non-SuperSpeed devices. To support this enumeration scheme on xhci the AddressDevice operation needs to be performed twice. The first instance of the command enables the HC's device and slot context info for the device, but omits sending the device a SetAddress command (BSR == block set address request). Then, after GetDescriptor completes, follow up with the full AddressDevice+SetAddress operation. As mentioned before, this ordering of events with USB3 devices causes an extra state transition to be exposed to xhci. Previously USB3 devices would transition directly from 'enabled' to 'addressed' and never need to underrun responses to 'get descriptor'. We do see the 64-byte descriptor fetch the correct data, but the following 18-byte descriptor read after the reset gets: bLength = 0 bDescriptorType = 0 bcdUSB = 0 bDeviceClass = 0 bDeviceSubClass = 0 bDeviceProtocol = 0 bMaxPacketSize0 = 9 instead of: bLength = 12 bDescriptorType = 1 bcdUSB = 300 bDeviceClass = 0 bDeviceSubClass = 0 bDeviceProtocol = 0 bMaxPacketSize0 = 9 which results in the discovery process looping until falling back to 'old scheme' enumeration.

2013-12-10xhci: Limit the spurious wakeup fix only to HP machinesTakashi Iwai1-1/+6
We've got regression reports that my previous fix for spurious wakeups after S5 on HP Haswell machines leads to the automatic reboot at shutdown on some machines. It turned out that the fix for one side triggers another BIOS bug in other side. So, it's exclusive. Since the original S5 wakeups have been confirmed only on HP machines, it'd be safer to apply it only to limited machines. As a wild guess, limiting to machines with HP PCI SSID should suffice. This patch should be backported to kernels as old as 3.12, that contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix spurious wakeups after S5 on Haswell".
