Since hardware\ndesigners seem to have settled on a relatively consistent set of register\ninterfaces this can be effectively factored out into shared code. There\nare a standard set of formats for marshalling data for exchange with the\ndevice, with the actual I/O mechanisms generally being simple byte\nstreams.\n\nWe create an abstraction for marshaling data into formats which can be\nsent on the control interfaces, and create a standard method for\nplugging in actual transport underneath that.\n\nThis is mostly a refactoring and renaming of the bottom level of the\nexisting code for sharing register I/O which we have in ASoC. A\nsubsequent patch in this series converts ASoC to use this. The main\ndifference in interface is that reads return values by writing to a\nlocation provided by a pointer rather than in the return value, ensuring\nwe can use the full range of the type for register data. We also use\nunsigned types rather than ints for the same reason.\n\nAs some of the devices can have very large register maps the existing\nASoC code also contains infrastructure for managing register caches.\nThis cache work will be moved over in a future stage to allow for\nseparate review, the current patch only deals with the physical I/O.\n\nSigned-off-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nAcked-by: Liam Girdwood \u003clrg@ti.com\u003e\nAcked-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nAcked-by: Wolfram Sang \u003cw.sang@pengutronix.de\u003e\nAcked-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\n" }, { "commit": "bbd9d6f7fbb0305c9a592bf05a32e87eb364a4ff", "tree": "12b2bb4202b05f6ae6a43c6ce830a0472043dbe5", "parents": [ "8e204874db000928e37199c2db82b7eb8966cc3c", "5a9a43646cf709312d71eca71cef90ad802f28f9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jul 22 19:02:39 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jul 22 19:02:39 2011 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: (107 commits)\n vfs: use ERR_CAST for err-ptr tossing in lookup_instantiate_filp\n isofs: Remove global fs lock\n jffs2: fix IN_DELETE_SELF on overwriting rename() killing a directory\n fix IN_DELETE_SELF on overwriting rename() on ramfs et.al.\n mm/truncate.c: fix build for CONFIG_BLOCK not enabled\n fs:update the NOTE of the file_operations structure\n Remove dead code in dget_parent()\n AFS: Fix silly characters in a comment\n switch d_add_ci() to d_splice_alias() in \"found negative\" case as well\n simplify gfs2_lookup()\n jfs_lookup(): don\u0027t bother with . or ..\n get rid of useless dget_parent() in btrfs rename() and link()\n get rid of useless dget_parent() in fs/btrfs/ioctl.c\n fs: push i_mutex and filemap_write_and_wait down into -\u003efsync() handlers\n drivers: fix up various -\u003ellseek() implementations\n fs: handle SEEK_HOLE/SEEK_DATA properly in all fs\u0027s that define their own llseek\n Ext4: handle SEEK_HOLE/SEEK_DATA generically\n Btrfs: implement our own -\u003ellseek\n fs: add SEEK_HOLE and SEEK_DATA flags\n reiserfs: make reiserfs default to barrier\u003dflush\n ...\n\nFix up trivial conflicts in fs/xfs/linux-2.6/xfs_super.c due to the new\nshrinker callout for the inode cache, that clashed with the xfs code to\nstart the periodic workers later.\n" }, { "commit": "6d16d6d9bb6f93e6f8506cfb3e91795d6443d54f", "tree": "92a1c9e4b645fa6d1fffedaeb56141b66f847320", "parents": [ "431bf99d26157d56689e5de65bd27ce9f077fc3f", "b395fb36d59e17b9335805c10fa30fc51c8a94c6" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jul 22 16:39:42 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jul 22 16:39:42 2011 -0700" }, "message": "Merge branch \u0027core-iommu-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027core-iommu-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n iommu/core: Fix build with INTR_REMAP\u003dy \u0026\u0026 CONFIG_DMAR\u003dn\n iommu/amd: Don\u0027t use MSI address range for DMA addresses\n iommu/amd: Move missing parts to drivers/iommu\n iommu: Move iommu Kconfig entries to submenu\n x86/ia64: intel-iommu: move to drivers/iommu/\n x86: amd_iommu: move to drivers/iommu/\n msm: iommu: move to drivers/iommu/\n drivers: iommu: move to a dedicated folder\n x86/amd-iommu: Store device alias as dev_data pointer\n x86/amd-iommu: Search for existind dev_data before allocting a new one\n x86/amd-iommu: Allow dev_data-\u003ealias to be NULL\n x86/amd-iommu: Use only dev_data in low-level domain attach/detach functions\n x86/amd-iommu: Use only dev_data for dte and iotlb flushing routines\n x86/amd-iommu: Store ATS state in dev_data\n x86/amd-iommu: Store devid in dev_data\n x86/amd-iommu: Introduce global dev_data_list\n x86/amd-iommu: Remove redundant device_flush_dte() calls\n iommu-api: Add missing header file\n\nFix up trivial conflicts (independent additions close to each other) in\ndrivers/Makefile and include/linux/pci.h\n" }, { "commit": "5da4e689449ad99ab31cf2208d99eddfce0498ba", "tree": "5cd8ccc145b8b29b3a63dd6252ee921d8e01379b", "parents": [ "69753a0f14d3cb2e8a70e559ef8d409e4deeac8a" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Jun 27 16:37:12 2011 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Jul 20 01:44:11 2011 -0400" }, "message": "devtmpfs: get rid of bogus mkdir in create_path()\n\nWe do _NOT_ want to mkdir the path itself - we are preparing to\nmknod it, after all.

This happens, for\nexample, if .runtime_resume() from one device\u0027s driver calls\npm_runtime_resume() for another device in the same PM domain.\nA similar situation may take place if a device\u0027s parent is in the\nsame PM domain, in which case the runtime PM framework may execute\npm_genpd_runtime_resume() automatically for the parent (if it is\nsuspended at the moment). This, of course, is undesirable, so\nthe generic PM domains code should be modified to prevent it from\nhappening.\n\nThe runtime PM framework guarantees that pm_genpd_runtime_suspend()\nand pm_genpd_runtime_resume() won\u0027t be executed in parallel for\nthe same device, so the generic PM domains code need not worry\nabout those cases. Still, it needs to prevent the other possible\nrace conditions between pm_genpd_runtime_suspend(),\npm_genpd_runtime_resume(), pm_genpd_poweron() and pm_genpd_poweroff()\nfrom happening and it needs to avoid deadlocks at the same time.\nTo this end, modify the generic PM domains code to relax\nsynchronization rules so that:\n\n* pm_genpd_poweron() doesn\u0027t wait for the PM domain status to\n change from GPD_STATE_BUSY. If it finds that the status is\n not GPD_STATE_POWER_OFF, it returns without powering the domain on\n (it may modify the status depending on the circumstances).\n\n* pm_genpd_poweroff() returns as soon as it finds that the PM\n domain\u0027s status changed from GPD_STATE_BUSY after it\u0027s released\n the PM domain\u0027s lock.\n\n* pm_genpd_runtime_suspend() doesn\u0027t wait for the PM domain status\n to change from GPD_STATE_BUSY after executing the domain\u0027s\n .stop_device() callback and executes pm_genpd_poweroff() only\n if pm_genpd_runtime_resume() is not executed in parallel.\n\n* pm_genpd_runtime_resume() doesn\u0027t wait for the PM domain status\n to change from GPD_STATE_BUSY after executing pm_genpd_poweron()\n and sets the domain\u0027s status to GPD_STATE_BUSY and increments its\n counter of resuming devices (introduced by this change) immediately\n after acquiring the lock. The counter of resuming devices is then\n decremented after executing __pm_genpd_runtime_resume() for the\n device and the domain\u0027s status is reset to GPD_STATE_ACTIVE (unless\n there are more resuming devices in the domain, in which case the\n status remains GPD_STATE_BUSY).\n\nThis way, for example, if a device driver\u0027s .runtime_resume()\ncallback executes pm_runtime_resume() for another device in the same\nPM domain, pm_genpd_poweron() called by pm_genpd_runtime_resume()\ninvoked by the runtime PM framework will not block and it will see\nthat there\u0027s nothing to do for it. Next, the PM domain\u0027s lock will\nbe acquired without waiting for its status to change from\nGPD_STATE_BUSY and the device driver\u0027s .runtime_resume() callback\nwill be executed. In turn, if pm_runtime_suspend() is executed by\none device driver\u0027s .runtime_resume() callback for another device in\nthe same PM domain, pm_genpd_poweroff() executed by\npm_genpd_runtime_suspend() invoked by the runtime PM framework as a\nresult will notice that one of the devices in the domain is being\nresumed, so it will return immediately.\n\nSigned-off-by: Rafael J.

However, as it\u0027s been determined recently,\nthere are multiple reasons not to do so, inlcuding:\n\n * The caller really doesn\u0027t control the runtime PM usage counters,\n because user space can access them through sysfs and effectively\n block runtime PM. That means using pm_runtime_suspend() or\n pm_runtime_get_sync() to suspend devices during system suspend\n may or may not work.\n\n * If a driver calls pm_runtime_suspend() from its .suspend()\n callback, it causes the subsystem\u0027s .runtime_suspend() callback to\n be executed, which leads to the call sequence:\n\n subsys-\u003esuspend(dev)\n driver-\u003esuspend(dev)\n pm_runtime_suspend(dev)\n subsys-\u003eruntime_suspend(dev)\n\n recursive from the subsystem\u0027s point of view. For some subsystems\n that may actually work (e.g. the platform bus type), but for some\n it will fail in a rather spectacular fashion (e.g. PCI). In each\n case it means a layering violation.\n\n * Both the subsystem and the driver can provide .suspend_noirq()\n callbacks for system suspend that can do whatever the\n .runtime_suspend() callbacks do just fine, so it really isn\u0027t\n necessary to call pm_runtime_suspend() during system suspend.\n\n * The runtime PM\u0027s handling of wakeup devices is usually different\n from the system suspend\u0027s one, so .runtime_suspend() may simply be\n inappropriate for system suspend.\n\n * System suspend is supposed to work even if CONFIG_PM_RUNTIME is\n unset.\n\n * The runtime PM workqueue is frozen before system suspend, so if\n whatever the driver is going to do during system suspend depends\n on it, that simply won\u0027t work.\n\nStill, there is a good reason to allow pm_runtime_resume() to\nsucceed during system suspend and resume (for instance, some\nsubsystems and device drivers may legitimately use it to ensure that\ntheir devices are in full-power states before suspending them).\nMoreover, there is no reason to prevent runtime PM callbacks from\nbeing executed in parallel with the system suspend/resume .prepare()\nand .complete() callbacks and the code removed by commit\ne8665002477f0278f84f898145b1f141ba26ee26 went too far in this\nrespect. On the other hand, runtime PM callbacks, including\n.runtime_resume(), must not be executed during system suspend\u0027s\n\"late\" stage of suspending devices and during system resume\u0027s \"early\"\ndevice resume stage.\n\nTaking all of the above into consideration, make the PM core\nacquire a runtime PM reference to every device and resume it if\nthere\u0027s a runtime PM resume request pending right before executing\nthe subsystem-level .suspend() callback for it. Make the PM core\ndrop references to all devices right after executing the\nsubsystem-level .resume() callbacks for them. Additionally,\nmake the PM core disable the runtime PM framework for all devices\nduring system suspend, after executing the subsystem-level .suspend()\ncallbacks for them, and enable the runtime PM framework for all\ndevices during system resume, right before executing the\nsubsystem-level .resume() callbacks for them.\n\nSigned-off-by: Rafael J.

This is the case, because\nthe drivers\u0027 .freeze() callbacks are executed after the hibernate\nmemory preallocation has been carried out and the preallocated amount\nof memory may be too small to cover the new driver allocations.\nUnfortunately, the drivers\u0027 .prepare() callbacks also are executed\nafter the hibernate memory preallocation has completed, so they are\nnot suitable for allocating additional memory either. Thus the only\nway a driver can safely allocate memory during hibernation is to use\na hibernate/suspend notifier.

On those systems it is not desirable to\nexecute device drivers\u0027 PM callbacks until it is known that power is\ngoing to be removed from the devices in question, which means that\nthey should be executed by power domain callbacks rather then by\nsubsystem (e.g. bus type) PM callbacks, because subsystems generally\nhave no information about what devices belong to which power domain.\nThus, for instance, if the bus type in question is the platform bus\ntype, its PM callbacks generally should not be called in addition to\npower domain callbacks, because they run device drivers\u0027 callbacks\nunconditionally if defined.\n\nWhile in principle the default subsystem PM callbacks, or a subset of\nthem, may be replaced with different functions, it doesn\u0027t seem\ncorrect to do so, because that would change the subsystem\u0027s behavior\nwith respect to all devices in the system, regardless of whether or\nnot they belong to any power domains. Thus, the only remaining\noption is to make power domain callbacks take precedence over\nsubsystem callbacks.\n\nSigned-off-by: Rafael J.

In\nturn, the runtime PM core code only calls one of those callbacks at\na time, preferring bus type callbacks to device type or class\ncallbacks and device type callbacks to class callbacks.\n\nIt seems reasonable to make them both behave in the same way in that\nrespect. Moreover, even though a device may belong to two subsystems\n(eg. bus type and device class) simultaneously, in practice power\nmanagement callbacks for system-wide power transitions are always\nprovided by only one of them (ie. if the bus type callbacks are\ndefined, the device class ones are not and vice versa). Thus it is\npossible to modify the code handling system-wide power transitions\nso that it follows the core runtime PM code (ie. treats the\nsubsystem callbacks as mutually exclusive).\n\nOn the other hand, the core runtime PM code will choose to execute,\nfor example, a runtime suspend callback provided by the device type\neven if the bus type\u0027s struct dev_pm_ops object exists, but the\nruntime_suspend pointer in it happens to be NULL. This is confusing,\nbecause it may lead to the execution of callbacks from different\nsubsystems during different operations (eg. the bus type suspend\ncallback may be executed during runtime suspend of the device, while\nthe device type callback will be executed during system suspend).\n\nMake all of the power management code treat subsystem callbacks in\na consistent way, such that:\n(1) If the device\u0027s type is defined (eg. dev-\u003etype is not NULL)\n and its pm pointer is not NULL, the callbacks from dev-\u003etype-\u003epm\n will be used.\n(2) If dev-\u003etype is NULL or dev-\u003etype-\u003epm is NULL, but the device\u0027s\n class is defined (eg. dev-\u003eclass is not NULL) and its pm pointer\n is not NULL, the callbacks from dev-\u003eclass-\u003epm will be used.\n(3) If dev-\u003etype is NULL or dev-\u003etype-\u003epm is NULL and dev-\u003eclass is\n NULL or dev-\u003eclass-\u003epm is NULL, the callbacks from dev-\u003ebus-\u003epm\n will be used provided that both dev-\u003ebus and dev-\u003ebus-\u003epm are\n not NULL.\n\nSigned-off-by: Rafael J.
