ACPI: Add acpi_resource_consumer() to find device that claims a resource

2016-12-01T20:59:32Z

Add acpi_resource_consumer(). This takes a struct resource and searches the ACPI namespace for a device whose current resource settings (_CRS) includes the resource. It returns the device if it exists, or NULL if no device uses the resource. If more than one device uses the resource (this may happen in the case of bridges), acpi_resource_consumer() returns the first one found by acpi_get_devices() in its modified depth-first walk of the namespace.

ACPI: Implement acpi_dma_configure

2016-11-29T15:57:44Z

On DT based systems, the of_dma_configure() API implements DMA configuration for a given device. On ACPI systems an API equivalent to of_dma_configure() is missing which implies that it is currently not possible to set-up DMA operations for devices through the ACPI generic kernel layer. This patch fills the gap by introducing acpi_dma_configure/deconfigure() calls that for now are just wrappers around arch_setup_dma_ops() and arch_teardown_dma_ops() and also updates ACPI and PCI core code to use the newly introduced acpi_dma_configure/acpi_dma_deconfigure functions. Since acpi_dma_configure() is used to configure DMA operations, the function initializes the dma/coherent_dma masks to sane default values if the current masks are uninitialized (also to keep the default values consistent with DT systems) to make sure the device has a complete default DMA set-up. The DMA range size passed to arch_setup_dma_ops() is sized according to the device coherent_dma_mask (starting at address 0x0), mirroring the DT probing path behaviour when a dma-ranges property is not provided for the device being probed; this changes the current arch_setup_dma_ops() call parameters in the ACPI probing case, but since arch_setup_dma_ops() is a NOP on all architectures but ARM/ARM64 this patch does not change the current kernel behaviour on them.

ACPI: Add FWNODE_ACPI_STATIC fwnode type

2016-11-29T15:57:42Z

On systems booting with a device tree, every struct device is associated with a struct device_node, that provides its DT firmware representation. The device node can be used in generic kernel contexts (eg IRQ translation, IOMMU streamid mapping), to retrieve the properties associated with the device and carry out kernel operations accordingly. Owing to the 1:1 relationship between the device and its device_node, the device_node can also be used as a look-up token for the device (eg looking up a device through its device_node), to retrieve the device in kernel paths where the device_node is available. On systems booting with ACPI, the same abstraction provided by the device_node is required to provide look-up functionality. The struct acpi_device, that represents firmware objects in the ACPI namespace already includes a struct fwnode_handle of type FWNODE_ACPI as their member; the same abstraction is missing though for devices that are instantiated out of static ACPI tables entries (eg ARM SMMU devices). Add a new fwnode_handle type to associate devices created out of static ACPI table entries to the respective firmware components and create a simple ACPI core layer interface to dynamically allocate and free the corresponding firmware nodes so that kernel subsystems can use it to instantiate the nodes and associate them with the respective devices.

ACPI / platform: Add support for build-in properties

2016-11-09T23:30:29Z

We have a couple of drivers, acpi_apd.c and acpi_lpss.c, that need to pass extra build-in properties to the devices they create. Previously the drivers added those properties to the struct device which is member of the struct acpi_device, but that does not work. Those properties need to be assigned to the struct device of the platform device instead in order for them to become available to the drivers. To fix this, this patch changes acpi_create_platform_device function to take struct property_entry pointer as parameter.
