2014-07-24net: mlx5: Use ktime_get_ns()Thomas Gleixner1-2/+2
This code is beyond silly: struct timespec ts = ktime_get_ts(); ktime_t ktime = timespec_to_ktime(ts); Further down the code builds the delta of two ktime_t values and converts the result to nanoseconds. Use ktime_get_ns() and replace all the nonsense. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Eli Cohen <eli@mellanox.com> Signed-off-by: John Stultz <john.stultz@linaro.org>
2014-07-24Input: atmel_mxt_ts - download device config using firmware loaderNick Dyer1-3/+0
The existing implementation which encodes the configuration as a binary blob in platform data is unsatisfactory since it requires a kernel recompile for the configuration to be changed, and it doesn't deal well with firmware changes that move values around on the chip. Atmel define an ASCII format for the configuration which can be exported from their tools. This patch implements a parser for that format which loads the configuration via the firmware loader and sends it to the MXT chip.

2014-07-24Bluetooth: Fix issue with ADV_IND reports and auto-connection handlingMarcel Holtmann1-0/+1
When adding remote devices to the kernel using the Add Device management command, these devices are explicitly allowed to connect. This kind of incoming connections are possible even when the controller itself is not connectable. For BR/EDR this distinction is pretty simple since there is only one type of incoming connections. With LE this is not that simple anymore since there are ADV_IND and ADV_DIRECT_IND advertising events. The ADV_DIRECT_IND advertising events are send for incoming (slave initiated) connections only. And this is the only thing the kernel should allow when adding devices using action 0x01. This meaning of incoming connections is coming from BR/EDR and needs to be mapped to LE the same way. Supporting the auto-connection of devices using ADV_IND advertising events is an important feature as well. However it does not map to incoming connections. So introduce a new action 0x02 that allows the kernel to connect to devices using ADV_DIRECT_IND and in addition ADV_IND advertising reports. This difference is represented by the new HCI_AUTO_CONN_DIRECT value for only connecting to ADV_DIRECT_IND. For connection to ADV_IND and ADV_DIRECT_IND the old value HCI_AUTO_CONN_ALWAYS is used.

2014-07-24ACPICA: Add new GPE public interface - acpi_mark_gpe_for_wake.Rafael J. Wysocki1-0/+4
ACPICA commit c49dbfed2bc069d0038ea7e1294409bfde7c2c8c Some potential callers of acpi_setup_gpe_for_wake may know in advance that there won't be any notify handlers installed for device wake notifications from the given GPE (one example is a button GPE in Linux). For these cases, acpi_mark_gpe_for_wake should be used instead of acpi_setup_gpe_for_wake. This will set the ACPI_GPE_CAN_WAKE flag for the GPE without trying to setup implicit wake notification for it (since there's no handler method). Rafael Wysocki. Signed-off-by: Rafael J.

2014-07-23svcrdma: Double the default credit limitChuck Lever1-2/+1
The RDMA credit limit controls how many concurrent RPCs are allowed per connection. An NFS/RDMA client and server exchange their credit limits in the RPC/RDMA headers. The Linux client and the Solaris client and server allow 32 credits. The Linux server allows only 16, which limits its performance. Set the server's default credit limit to 32, like the other well- known implementations, so the out-of-the-shrinkwrap performance of the Linux server is better.

2014-07-23ktime: Kill non-scalar ktime_t implementation for 2038John Stultz2-179/+5
The non-scalar ktime_t implementation is basically a timespec which has to be changed to support dates past 2038 on 32bit systems. This patch removes the non-scalar ktime_t implementation, forcing the scalar s64 nanosecond version on all architectures. This may have additional performance overhead on some 32bit systems when converting between ktime_t and timespec structures, however the majority of 32bit systems (arm and i386) were already using scalar ktime_t, so no performance regressions will be seen on those platforms. On affected platforms, I'm open to finding optimizations, including avoiding converting to timespecs where possible.

2014-07-23gpio: move gpio_ensure_requested() into legacy C fileAlexandre Courbot1-12/+3
gpio_ensure_requested() only makes sense when using the integer-based GPIO API, so make sure it is called from there instead of the gpiod API which we know cannot be called with a non-requested GPIO anyway. The uses of gpio_ensure_requested() in the gpiod API were kind of out-of-place anyway, so putting them in gpio-legacy.c helps clearing the code. Actually, considering the time this ensure_requested mechanism has been around, maybe we should just turn this patch into "remove gpio_ensure_requested()" if we know for sure that no user depend on it anymore?

2014-07-23video: fix up versatile CLCD helper moveArnd Bergmann1-0/+18
commit 11c32d7b6274cb0f ("video: move Versatile CLCD helpers") moved files out of the plat-versatile directory but in the process got a few of the dependencies wrong: - If CONFIG_FB is not set, the file no longer gets built, resulting in a link error - If CONFIG_FB or CONFIG_FB_ARMCLCD are disabled, we also get a Kconfig warning for incorrect dependencies due to the symbol being 'select'ed from the platform Kconfig. - When the file is not built, we also get a link error for missing symbols. This patch should fix all three, by removing the 'select' statements, changing the Kconfig description of the symbol to be enabled in exactly the right configurations, and adding inline stub functions for the case when the framebuffer driver is disabled.

2014-07-23gpio: drop retval check enforcing from gpiochip_remove()Linus Walleij1-1/+1
As we start to decomission the return value from gpiochip_remove() the compilers emit warnings due to the function being tagged __must_check. So drop this until we remove the return value altogether.

2014-07-23pinctrl: dra: dt-bindings: Fix pull enable/disableNishanth Menon1-3/+4
The DRA74/72 control module pins have a weak pull up and pull down. This is configured by bit offset 17. if BIT(17) is 1, a pull up is selected, else a pull down is selected. However, this pull resisstor is applied based on BIT(16) - PULLUDENABLE - if BIT(18) is *0*, then pull as defined in BIT(17) is applied, else no weak pulls are applied. We defined this in reverse.

2014-07-23drm/crtc: Add property for aspect ratioVandana Kannan2-0/+7
Added a property to enable user space to set aspect ratio. This patch contains declaration of the property and code to create the property. v2: Thierry's review comments. - Made aspect ratio enum generic instead of HDMI/CEA specfic - Removed usage of temporary aspect_ratio variable v3: Thierry's review comments. - Fixed indentation v4: Thierry's review comments. - Return ENOMEM when property creation fails Signed-off-by: Vandana Kannan <vandana.kannan@intel.com> Cc: Thierry Reding <thierry.reding@gmail.com> Reviewed-by: Thierry Reding <treding@nvidia.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
