git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "The first real batch of fixes for this release cycle, so there are a few more than usual. Most of these are fixes and tweaks to board support (DT bugfixes, etc). I've also picked up a couple of small cleanups that seemed innocent enough that there was little reason to wait (const/ __initconst and Kconfig deps). Quite a bit of the changes on OMAP were due to fixes to no longer write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but there were also other fixes. Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC fixes on OMAP5, and Nomadik had changes to MMC parameters in DT. All in all, mostly the usual mix of various fixes" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (46 commits) ARM: multi_v7_defconfig: enable DW_WATCHDOG ARM: nomadik: fix up SD/MMC DT settings ARM64: tegra: Add chosen node for tegra132 norrin ARM: realview: use "depends on" instead of "if" after prompt ARM: tango: use "depends on" instead of "if" after prompt ARM: tango: use const and __initconst for smp_operations ARM: realview: use const and __initconst for smp_operations bus: uniphier-system-bus: revive tristate prompt arm64: dts: Add missing DMA Abort interrupt to Juno bus: vexpress-config: Add missing of_node_put ARM: dts: am57xx: sbc-am57x: correct Eth PHY settings ARM: dts: am57xx: cl-som-am57x: fix CPSW EMAC pinmux ARM: dts: am57xx: sbc-am57x: fix UART3 pinmux ARM: dts: am57xx: cl-som-am57x: update SPI Flash frequency ARM: dts: am57xx: cl-som-am57x: set HOST mode for USB2 ARM: dts: am57xx: sbc-am57x: fix SB-SOM EEPROM I2C address ARM: dts: LogicPD Torpedo: Revert Duplicative Entries ARM: dts: am437x: pixcir_tangoc: use correct flags for irq types ARM: dts: am4372: fix irq type for arm twd and global timer ARM: dts: at91: sama5d4 xplained: fix phy0 IRQ type ...

2016-02-05drm/dp/mst: deallocate payload on port destructionMykola Lysenko1-8/+83
This is needed to properly deallocate port payload after downstream branch get unplugged. In order to do this unplugged MST topology should be preserved, to find first alive port on path to unplugged MST topology, and send payload deallocation request to branch device of found port. For this mstb and port kref's are used in reversed order to track when port and branch memory could be freed. Added additional functions to find appropriate mstb as described above.

2016-02-05drm/dp/mst: move GUID storage from mgr, port to only mst branchHersen Wu1-36/+28
Previous implementation does not handle case below: boot up one MST branch to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output of 1st MST, GUID is not created for 2nd MST branch. When downstream port of 2nd MST branch send upstream request, it fails because 2nd MST branch GUID is not available. New Implementation: only create GUID for MST branch and save it within Branch.

2016-02-05drm/dp/mst: change MST detection schemeMykola Lysenko1-18/+19
1. Get edid for all connected MST displays, not only on logical ports, in the same thread as MST topology detection is done: There are displays that have branches inside w/o logical ports. So in case another SST display connected downstream system can end-up in situation when 3 DOWN requests sent: two for ‘remote i2c read’ and one for ‘enum path resources’, making slots full. 2. Call notification callback in one place in the end of topology discovery/update: This is done to reduce number of events sent to userspace in case complex topology discovery is going, adding multiple number of connectors; 3. Remove notification callback call from short pulse interrupt processing function: This is done in order not to block interrupt processing function, in case any MST request will be made from it. Notification will be send from topology discovery/update work item.

2016-02-05xhci: harden xhci_find_next_ext_cap against device removalJoe Lawrence1-0/+4
xhci_find_next_ext_cap doesn't check for PCI hotplug removal and may use the PCI master abort bit pattern (~0) to calculate a new PCI address offset to read/write. The has lead to reproducable crashes when testing surprise removal during device initialization on a Stratus platform, at least after commit d5ddcdf4d672 ("xhci: rework xhci extended capability list parsing functions"). The crash is repeatable on a Stratus platform when injecting hardware faults to induce xHCI host controller hotplug during driver initialization. If a PCI read in xhci_find_next_ext_cap returns the master abort pattern, quirk_usb_handoff_xhci may start using a bogus ext_cap_offset to start searching more bogus PCI addresses.

2016-02-04[media] vb2-core: call threadio->fnc() if !VB2_BUF_STATE_ERRORMauro Carvalho Chehab1-1/+1
changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb. The root cause is that, instead of calling threadio->fnc() for all types of events except for VB2_BUF_STATE_ERROR, it was calling it only for VB2_BUF_STATE_DONE. With that, the DVB thread were never called. Cc: stable@vger.kernel.org # Kernel >= 4.3 Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-04[media] vb2: fix nasty vb2_thread regressionHans Verkuil2-53/+44
The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed. Tested with vivid and the cobalt driver.

when ip fails to enter sleep mode, register access protection will be disabled, at the same time if all clocks are disabled, access register will hang up AHB bus. the common case causes ip sleep failure is that after all ports enter U3 but before ip enters sleep mode, a port receives a resume signal('K'). this will happens when such as clicks mouse to try to do remote-wakeup to stop system enter suspend. so stop polling root hubs to avoid access xHCI register on bus suspend, and restart it when bus resumes.

2016-02-04Revert "xhci: don't finish a TD if we get a short-transfer event mid TD"Mathias Nyman1-10/+0
This reverts commit e210c422b6fd ("xhci: don't finish a TD if we get a short transfer event mid TD") Turns out that most host controllers do not follow the xHCI specs and never send the second event for the last TRB in the TD if there was a short event mid-TD. Returning the URB directly after the first short-transfer event is far better than never returning the URB. (class drivers usually timeout after 30sec). For the hosts that do send the second event we will go back to treating it as misplaced event and print an error message for it.

2016-02-03PM: Avoid false-positive warnings in dev_pm_domain_set()Rafael J. Wysocki1-1/+1
There is a WARN_ON() in dev_pm_domain_set() that triggers on attempts to set the pm_domain pointer for devices with a driver bound. However, that WARN_ON() triggers on attempts to clear the pointer too and the test it uses is based on checking the device's p->knode_driver pointer which still is set when the device bus type's/driver's ->remove callback has been executed. This leads to false-positive warnings when bus type code calls dev_pm_domain_set() to clear the pm_domain pointer after invoking the driver's ->remove() callback. To avoid those false-positives, make dev_pm_domain_set() check if the pointer passed to it is NULL and skip the warning in that case.
