2012-08-23PCI: Wait for pending transactions to complete before 82599 FLRBjorn Helgaas
Before initiating an FLR, we should wait for completion of any outstanding non-posted requests. See PCIe spec r3.0, sec 6.6.2. This makes reset_intel_82599_sfp_virtfn() very similar to the generic pcie_flr(). The only difference is that the 82599 doesn't report FLR support in the VF Device Capability register.

2012-08-23PCI: Add accessors for PCI Express CapabilityJiang Liu
The PCI Express Capability (PCIe spec r3.0, sec 7.8) comes in two versions, v1 and v2. In v1 Capability structures (PCIe spec r1.0 and r1.1), some fields are optional, so the structure size depends on the device type. This patch adds functions to access this capability so drivers don't have to be aware of the differences between v1 and v2. Note that these new functions apply only to the "PCI Express Capability," not to any of the other "PCI Express Extended Capabilities" (AER, VC, ACS, MFVC, etc.) Function pcie_capability_read_word/dword() reads the PCIe Capabilities register and returns the value in the reference parameter "val". If the PCIe Capabilities register is not implemented on the PCIe device, "val" is set to 0. Function pcie_capability_write_word/dword() writes the value to the specified PCIe Capability register. Function pcie_capability_clear_and_set_word/dword() sets and/or clears bits of a PCIe Capability register.

Pull ARM DMA engine updates from Russell King: "This looks scary at first glance, but what it is is: - a rework of the sa11x0 DMA engine driver merged during the previous cycle, to extract a common set of helper functions for DMA engine implementations. - conversion of amba-pl08x.c to use these helper functions. - addition of OMAP DMA engine driver (using these helper functions), and conversion of some of the OMAP DMA users to use DMA engine. Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."

2012-08-02raid5: make_request use batch stripe releaseShaohua Li
make_request() does stripe release for every stripe and the stripe usually has count 1, which makes previous release_stripe() optimization not work. In my test, this release_stripe() becomes the heaviest pleace to take conf->device_lock after previous patches applied. Below patch makes stripe release batch. All the stripes will be released in unplug. The STRIPE_ON_UNPLUG_LIST bit is to protect concurrent access stripe lru.

Commit ca5481c68e9fbcea62bb3c78ae6cccf99ca8fb73 ("sh: pfc: Rudimentary pinctrl-backed GPIO support.") introduced a regression for platforms that were doing early GPIO API calls (from arch_initcall() or earlier), leading to a situation where our two-stage registration logic would trip itself up and we'd -ENODEV out of the pinctrl registration path, resulting in endless -EPROBE_DEFER errors. Further lack of checking any sort of errors from gpio_request() resulted in boot time warnings, tripping on the FLAG_REQUESTED test-and-set in gpio_ensure_requested(). As it turns out there's no particular need to bother with the two-stage registration, as the platform bus is already available at the point that we have to start caring. As such, it's easiest to simply fold these together in to a single init path, the ordering of which is ensured through the platform's mux registration, as usual. Reported-by: Rafael J.

2012-07-31Platform: OLPC: move global variables into priv structAndres Salomon
Populate olpc_ec_priv with variables that were previously global. This makes things a tad bit clearer, IMO. Signed-off-by: Andres Salomon <dilinger@queued.net> Acked-by: Paul Fox <pgf@laptop.org> Reviewed-by: Thomas Gleixner <tglx@linutronix.de>
2012-07-31Platform: OLPC: move debugfs support from x86 EC driverAndres Salomon
There's nothing about the debugfs interface for the EC driver that is architecture-specific, so move it into the arch-independent driver. The code is mostly unchanged with the exception of renamed variables, coding style changes, and API updates.

2012-07-31x86: OLPC: switch over to using new EC driver on x86Andres Salomon
This uses the new EC driver framework in drivers/platform/olpc. The XO-1 and XO-1.5-specific code is still in arch/x86, but the generic stuff (including a new workqueue; no more running EC commands with IRQs disabled!) can be shared with other architectures.

2012-07-31Platform: OLPC: add a suspended flag to the EC driverAndres Salomon
A problem we've noticed on XO-1.75 is when we suspend in the middle of an EC command. Don't allow that. In the process, create a private object for the generic EC driver to use; we have a framework for passing around a struct, use that rather than a proliferation of global variables.
