2016-09-22[media] media: Refactor copying IOCTL arguments from and to user spaceSakari Ailus
Refactor copying the IOCTL argument structs from the user space and back, in order to reduce code copied around and make the implementation more robust. As a result, the copying is done while not holding the graph mutex.

2016-09-22[media] exynos4-is: add of_platform_populate() call for FIMC-IS child devicesSylwester Nawrocki
Instead of relying on the "simple-bus" compatible and the driver core populating FIMC-IS child devices make the fimc-is driver populating its child devices. This prevents issues related to accessing ISP_I2C clock registers with corresponding power domain switched off, which popped out after applying some pending IOMMU driver patches. Now the I2C_ISP child devices will be instantiated only when required parent device drivers are initialized and ready.

2016-09-22[media] exynos4-is: Clear isp-i2c adapter power.ignore_children flagSylwester Nawrocki
Since commit 04f59143b571161d25315dd52d7a2ecc022cb71a ("i2c: let I2C masters ignore their children for PM") the power.ignore_children flag is set when registering an I2C adapter. Since I2C transfers are not managed by the fimc-isp-i2c driver its clients use pm_runtime_* calls directly to communicate required power state of the bus controller. However, when the power.ignore_children flag is set that doesn't work, so clear that flag back after registering the adapter. While at it drop pm_runtime_enable() call on the i2c_adapter as it is already done by the I2C subsystem when registering I2C adapter. This patch is meant as a minimal change to fix the regression, eventually the I2C_ISPx clock handling will be moved to the top level fimc-is driver and whole runtime PM code is going to be dropped from the fimc-is-i2c module.

2016-09-22drm/i2c: tda998x: don't register the connectorBrian Starkey
The connector shouldn't be registered until the rest of the whole device is set up, so that consistent state is presented to userspace. As drm_dev_register() now registers all of the connectors anyway, there's no need to explicitly do it in individual drivers so remove the calls to drm_connector_register()/drm_connector_unregister().

2016-09-22crypto: omap-sham - add support functions for sg based data handlingTero Kristo
Currently omap-sham uses a huge internal buffer for caching data, and pushing this out to the DMA as large chunks.

This patch adds support functions for (mostly) scatterlist based data handling. omap_sham_prepare_request() prepares a scatterlist for DMA transfer to SHA crypto accelerator. This requires checking the data / offset / length alignment of the data, splitting the data to SHA block size granularity, and adding any remaining data back to the buffer. With this patch, the code doesn't actually go live yet, the support code will be taken properly into use with additional patches that modify the SHA driver functionality itself.
