* iio: bmc150: introduce bmc150_accel_interruptOctavian Purdila2015-03-141-35/+51
| | | | | | | | | | | | | | | | Since both triggers and events can share an interrupt, add a data structure that tracks the users of an interrupt so that it enables or disables it only for the first users and respectively last user. This will allows us to easily add more events or triggers. The patch also adds an interrupt enabled counter, so that we can easily know if we need to put the device in normal mode when the resume callback is issued.

* iio: imu: inv_mpu6050: Create mux clients for ACPISrinivas Pandruvada2015-02-254-1/+222
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a follow up patches after adding i2c mux adapter for bypass mode. Potentially many different types of sensor can be attached to INVMPU6XXX device, which can be connected to main cpu i2c bus in bypass mode. Why do we need this? The system ACPI table entry will consist of only one device for INV6XXX, assuming that this driver will handle all connected sensors. That is not true for the Linux driver. There are bunch of IIO drivers for each sensors, hence we created a mux on this device. So to load these additional drivers, we need to create i2c devices for them in this driver using this mux adapter. There are multiple options: 1. Use the auto detect feature, this needs a new i2c class for the adapter as the existing HWMON class is not acceptable. Also the autodetect has overhead of executing detect method for each matching class of adapters. This is a simple implementation. This option was previously submitted with not a happy feedback. 2. Option is use ACPI magic and parse the configuration data. What we need to create a i2c device at a minimum is address and a name. Address can be obtained for secondary device in more or less in a standard way from using _CRS element. But there is no name. To get name we need to process proprietary vendor data. Not having name is not fun, as you have to create device using the device name of INVN6XXXX, respecting driver duplicate name space restriction. Also each client driver needs to have this name in the id table. Since multiple driver can be loaded, the driver should be able to detect its presence and gracefully exit for the other client driver to take it over. So we use two step process: - Use DMI to id platform and parse propritery data. This is not uncommon for many x86 platform specific driver. We will get both name and address. The change created necessary infrastructure to add more properitery vendor data parsing. - If DMI match fails, then create device on INV6XXX-client (we can't create with same name as INV6XXX as it will cause duplicate name and driver model will reject.) With this each client sensor driver which needs to get attached via INV6XXXX, need this name in the id table and detect the physical presence of sensor in probe and exit if not found.

To fix this issue specific to non-multiplatform r8a7790 and Lager: 1) Instantiate the GIC from platform board code and also 2) Skip over the DT arch timer as well as 3) Force delay setup based on DT CPU frequency With these 3 fixes in place interrupts on Lager are now unbroken.

| | | * ARM: shmobile: r8a73a4: Instantiate GIC from C board code in legacy buildsMagnus Damm2015-01-292-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of commit 9a1091ef0017c40a ("irqchip: gic: Support hierarchy irq domain."), the APE6EVM legacy board support is known to be broken. The IRQ numbers of the GIC are now virtual, and no longer match the hardcoded hardware IRQ numbers in the legacy platform board code. To fix this issue specific to non-muliplatform r8a73a4 and APE6EVM: 1) Instantiate the GIC from platform board code and also 2) Skip over the DT arch timer as well as 3) Force delay setup based on DT CPU frequency With these 3 fixes in place interrupts on APE6EVM are now unbroken. Partially based on legacy GIC fix by Geert Uytterhoeven, thanks to him for the initial work.

| | * | arm: dma-mapping: Set DMA IOMMU ops in arm_iommu_attach_device()Laurent Pinchart2015-01-291-15/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 4bb25789ed28228a ("arm: dma-mapping: plumb our iommu mapping ops into arch_setup_dma_ops") moved the setting of the DMA operations from arm_iommu_attach_device() to arch_setup_dma_ops() where the DMA operations to be used are selected based on whether the device is connected to an IOMMU. However, the IOMMU detection scheme requires the IOMMU driver to be ported to the new IOMMU of_xlate API. As no driver has been ported yet, this effectively breaks all IOMMU ARM users that depend on the IOMMU being handled transparently by the DMA mapping API. Fix this by restoring the setting of DMA IOMMU ops in arm_iommu_attach_device() and splitting the rest of the function into a new internal __arm_iommu_attach_device() function, called by arch_setup_dma_ops().
