2016-01-07dmaengine: dw: platform: power on device on shutdownAndy Shevchenko
We have to call dw_dma_disable() to stop any ongoing transfer. On some platforms we can't do that since DMA device is powered off. Moreover we have no possibility at that point to check if the platform is affected or not. That's why we call pm_runtime_get_sync() / pm_runtime_put() unconditionally. On the other hand we can't use pm_runtime_suspended() because runtime PM framework is not fully used by the driver.

2016-01-07ACPI / LPSS: override power state for LPSS DMA deviceAndy Shevchenko
This is a third approach to workaround long standing issue with LPSS on BayTrail. First one [1] was reverted since it didn't resolve the issue comprehensively. Second one [2] was rejected by internal review. The LPSS DMA controller does not have neither _PS0 nor _PS3 method. Moreover it can be powered off automatically whenever the last LPSS device goes down. In case of no power any access to the DMA controller will hang the system. The behaviour is reproduced on some HP laptops based on Intel BayTrail [3,4] as well as on ASuS T100TA transformer. Power on the LPSS island through the registers accessible in a specific way.

2016-01-07iommu/dma: Use correct offset in map_sgRobin Murphy
When mapping a non-page-aligned scatterlist entry, we copy the original offset to the output DMA address before aligning it to hand off to iommu_map_sg(), then later adding the IOVA page address portion to get the final mapped address. However, when the IOVA page size is smaller than the CPU page size, it is the offset within the IOVA page we want, not that within the CPU page, which can easily be larger than an IOVA page and thus result in an incorrect final address. Fix the bug by taking only the IOVA-aligned part of the offset as the basis of the DMA address, not the whole thing.

2016-01-05ACPI / video: driver must be registered before checking for keypressesAdrien Schildknecht
acpi_video_handles_brightness_key_presses() may use an uninitialized mutex. The error has been reported by lockdep: DEBUG_LOCKS_WARN_ON(l->magic != l). The function assumes that the video driver has been registered before being called. As explained in the comment of acpi_video_init(), the registration of the video class may be defered and thus may not take place in the init function of the module. Use completion mechanisms to make sure that acpi_video_handles_brightness_key_presses() wait for the completion of acpi_video_register() before using the mutex. Also get rid of register_count since task completion can replace it.

2016-01-04ACPICA: Drop Linux-specific waking vector functionsRafael J. Wysocki
Commit f06147f9fbf1 (ACPICA: Hardware: Enable firmware waking vector for both 32-bit and 64-bit FACS) added three functions that aren't present in upstream ACPICA, acpi_hw_set_firmware_waking_vectors(), acpi_set_firmware_waking_vectors() and acpi_set_firmware_waking_vector64(), to allow Linux to use the previously existing API for setting the platform firmware waking vector. However, that wasn't necessary, since the ACPI sleep support code in Linux can be modified to use the upstream ACPICA's API easily and the additional functions may be dropped which reduces the code size and puts the kernel's ACPICA code more in line with the upstream. Make the changes as per the above. While at it, make the relevant function desctiption comments reflect the upstream ACPICA's ones. Signed-off-by: Rafael J.

2016-01-04mtd: fix cmdlinepart parser, early naming for auto-filled MTDBrian Norris
Commit 807f16d4db95 ("mtd: core: set some defaults when dev.parent is set") attempted to provide some default settings for MTDs that (a) assign the parent device and (b) don't provide their own name or owner However, this isn't a perfect drop-in replacement for the boilerplate found in some drivers, because the MTD name is used by partition parsers like cmdlinepart, but the name isn't set until add_mtd_device(), after the parsing is completed. This means cmdlinepart sees a NULL name and therefore will not work properly. Fix this by moving the default name and owner assignment to be first in the MTD registration process. [Note: this does not fix all reported issues, particularly with NAND drivers. Will require an additional fix for drivers/mtd/nand/] Fixes: 807f16d4db95 ("mtd: core: set some defaults when dev.parent is set") Reported-by: Heiko Schocher <hs@denx.de> Signed-off-by: Brian Norris <computersforpeace@gmail.com> Cc: Heiko Schocher <hs@denx.de> Cc: Frans Klaver <fransklaver@gmail.com>

2016-01-01ACPICA: Add per-table execution of module-level codeBob Moore
ACPICA commit 071eff738c59eda1792ac24b3b688b61691d7e7c Execute any module-level code after each ACPI table (DSDT or SSDT) is loaded into the namespace (rather than after all AML tables have been loaded). This matches the behavior of other ACPI implementations and is required to support BIOS code that depends on this behavior.

2016-01-01ACPICA: Events: Introduce ACPI_REG_DISCONNECT invocation to ↵Lv Zheng
acpi_ev_execute_reg_methods() ACPICA commit 1cf1a1e090f61f0c27f1dcf1905c7cc79a9c51c8 It is likely that we should synchronously invoke _REG(DISCONNECT) only when the acpi_remove_address_space_handler() is invoked because of dependencies. If it is invoked when the object is not referenced, problem may occur if the operation region fields accessed in _REG are no longer driven by any device driver. Noticed that _REG(CONNECT)/_REG(DISCONNECT) only mean to inform the AML of the handler availability, no return value is required for the caller. This patch only introduces ACPI_REG_DISCONNECT invaocation, but doesn't introduce a real change. Lv Zheng.
