2017-04-08firmware: Add coreboot device tree binding documentationJulius Werner
This patch adds documentation describing a device tree binding for the coreboot firmware. It is meant to be dynamically added during boot and contains address definitions for the coreboot table (a list of variable-sized descriptors providing information about various compile- and run-time generated firmware parameters) and the CBMEM area (the structure containing most run-time resident memory regions set up by coreboot). These definitions allow kernel drivers to easily access data contained in and pointed to by these regions (such as coreboot's in-memory log). (An example implementation can be seen in the following patch) Signed-off-by: Julius Werner <jwerner@chromium.org> Signed-off-by: Thierry Escande <thierry.escande@collabora.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-04-07pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()Tony Lindgren
Recent pinctrl changes to allow dynamic allocation of pins exposed one more issue with the pinctrl pins claimed early by the controller itself. This caused a regression for IMX6 pinctrl hogs. Before enabling the pin controller driver we need to wait until it has been properly initialized, then claim the hogs, and only then enable it. To fix the regression, split the code into pinctrl_claim_hogs() and pinctrl_enable(). And then let's require that pinctrl_enable() is always called by the pin controller driver when ready after calling pinctrl_register_and_init().

2017-04-06iommu: Allow default domain type to be set on the kernel command lineWill Deacon
The IOMMU core currently initialises the default domain for each group to IOMMU_DOMAIN_DMA, under the assumption that devices will use IOMMU-backed DMA ops by default. However, in some cases it is desirable for the DMA ops to bypass the IOMMU for performance reasons, reserving use of translation for subsystems such as VFIO that require it for enforcing device isolation. Rather than modify each IOMMU driver to provide different semantics for DMA domains, instead we introduce a command line parameter that can be used to change the type of the default domain. Passthrough can then be specified using "iommu.passthrough=1" on the kernel command line. Signed-off-by: Will Deacon <will.deacon@arm.com>
2017-04-06iommu/arm-smmu: Add global SMR masking propertyRobin Murphy
The current SMR masking support using a 2-cell iommu-specifier is primarily intended to handle individual masters with large and/or complex Stream ID assignments; it quickly gets a bit clunky in other SMR use-cases where we just want to consistently mask out the same part of every Stream ID (e.g. for MMU-500 configurations where the appended TBU number gets in the way unnecessarily). Let's add a new property to allow a single global mask value to better fit the latter situation.
