frequencies MPU DPLL on OMAP5, DRA75x, DRA72x has a limitation on the maximum frequency it can be locked at. Duty Cycle Correction circuit is used to recover a correct duty cycle for achieving higher frequencies (hardware internally switches output to M3 output(CLKOUTHIF) from M2 output (CLKOUT)). So provide support to setup required data to handle Duty cycle by the setting up the minimum frequency for DPLL. 1.4GHz is common for all these devices and is based on Technical Reference Manual information for OMAP5432((SWPU282U) chapter 3.6.3.3.1 "DPLLs Output Clocks Parameters", and equivalent information from DRA75x, DRA72x documentation(SPRUHP2E, SPRUHI2P).

2014-06-06rbd: use reference counts for image requestsAlex Elder
Each image request contains a reference count, but to date it has not actually been used. (I think this was just an oversight.) A recent report involving rbd failing an assertion shed light on why and where we need to use these reference counts. Every OSD request associated with an object request uses rbd_osd_req_callback() as its callback function. That function will call a helper function (dependent on the type of OSD request) that will set the object request's "done" flag if the object request if appropriate. If that "done" flag is set, the object request is passed to rbd_obj_request_complete(). In rbd_obj_request_complete(), requests are processed in sequential order. So if an object request completes before one of its predecessors in the image request, the completion is deferred. Otherwise, if it's a completing object's "turn" to be completed, it is passed to rbd_img_obj_end_request(), which records the result of the operation, accumulates transferred bytes, and so on. Next, the successor to this request is checked and if it is marked "done", (deferred) completion processing is performed on that request, and so on. If the last object request in an image request is completed, rbd_img_request_complete() is called, which (typically) destroys the image request. There is a race here, however. The instant an object request is marked "done" it can be provided (by a thread handling completion of one of its predecessor operations) to rbd_img_obj_end_request(), which (for the last request) can then lead to the image request getting torn down. And this can happen *before* that object has itself entered rbd_img_obj_end_request(). As a result, once it *does* enter that function, the image request (and even the object request itself) may have been freed and become invalid. All that's necessary to avoid this is to properly count references to the image requests. We tear down an image request's object requests all at once--only when the entire image request has completed. So there's no need for an image request to count references for its object requests. However, we don't want an image request to go away until the last of its object requests has passed through rbd_img_obj_callback(). In other words, we don't want rbd_img_request_complete() to necessarily result in the image request being destroyed, because it may get called before we've finished processing on all of its object requests. So the fix is to add a reference to an image request for each of its object requests. The reference can be viewed as representing an object request that has not yet finished its call to rbd_img_obj_callback(). That is emphasized by getting the reference right after assigning that as the image object's callback function. The corresponding release of that reference is done at the end of rbd_img_obj_callback(), which every image object request passes through exactly once.

2014-06-05Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into nextLinus Torvalds
Pull ARM updates from Russell King: - Major clean-up of the L2 cache support code. The existing mess was becoming rather unmaintainable through all the additions that others have done over time. This turns it into a much nicer structure, and implements a few performance improvements as well. - Clean up some of the CP15 control register tweaks for alignment support, moving some code and data into alignment.c - DMA properties for ARM, from Santosh and reviewed by DT people. This adds DT properties to specify bus translations we can't discover automatically, and to indicate whether devices are coherent. - Hibernation support for ARM - Make ftrace work with read-only text in modules - add suspend support for PJ4B CPUs - rework interrupt masking for undefined instruction handling, which allows us to enable interrupts earlier in the handling of these exceptions. - support for big endian page tables - fix stacktrace support to exclude stacktrace functions from the trace, and add save_stack_trace_regs() implementation so that kprobes can record stack traces. - Add support for the Cortex-A17 CPU. - Remove last vestiges of ARM710 support. - Removal of ARM "meminfo" structure, finally converting us solely to memblock to handle the early memory initialisation. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (142 commits) ARM: ensure C page table setup code follows assembly code (part II) ARM: ensure C page table setup code follows assembly code ARM: consolidate last remaining open-coded alignment trap enable ARM: remove global cr_no_alignment ARM: remove CPU_CP15 conditional from alignment.c ARM: remove unused adjust_cr() function ARM: move "noalign" command line option to alignment.c ARM: provide common method to clear bits in CPU control register ARM: 8025/1: Get rid of meminfo ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type ARM: 8066/1: correction for ARM patch 8031/2 ARM: 8049/1: ftrace/add save_stack_trace_regs() implementation ARM: 8065/1: remove last use of CONFIG_CPU_ARM710 ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instruction ARM: 8047/1: rwsem: use asm-generic rwsem implementation ARM: l2c: trial at enabling some Cortex-A9 optimisations ARM: l2c: add warnings for stuff modifying aux_ctrl register values ARM: l2c: print a warning with L2C-310 caches if the cache size is modified ARM: l2c: remove old .set_debug method ARM: l2c: kill L2X0_AUX_CTRL_MASK before anyone else makes use of this ...

The SYSTEMPORT driver uses libphy to determine the carrier state, so make sure we start with a carrier off until libphy has completed the link training process. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-06-05net: systemport: fix transmit locking schemeFlorian Fainelli
Our transmit locking scheme did not account for the TX ring full interrupt. If a TX ring full interrupt fires while we are attempting to transmit, we will cause a deadlock to occur. Fix this by making sure that we properly disable interrupts while acquiring the spinlock. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-06-05dm9000: avoid sleeping in dm9000_timeout callbackAndrew Ruder
On the DM9000B, dm9000_msleep() is called during the dm9000_timeout() routine. Since dm9000_timeout() holds the main spinlock through the entire routine, mdelay() needs to be used rather than msleep(). Furthermore, the mutex_lock()/mutex_unlock() should be avoided so as to not sleep with spinlocks held. Signed-off-by: Andrew Ruder <andrew.ruder@elecsyscorp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-06-05dm9000: handle initial link statusAndrew Ruder
On the DM9000A/DM9000B force the initial check of the link status. The DM9000A/B has a link status changed event and this interrupt bit isn't always set out of reset when a cable is plugged in. This results in the driver not seeing the cable attached link status until the cable is removed and plugged in again.

2014-06-05dm9000: remove redundant ISR status clearAndrew Ruder
Since dm9000_interrupt() is already reading/clearing every set bit in DM9000_ISR, this additional clear in dm9000_rx() (which is only called by dm9000_interrupt()) is unnecessary and can be removed.
