* irqchip: nps: add 64BIT dependencyArnd Bergmann2016-05-201-0/+1
| | | | | | | | | | | | | | | | The newly added nps irqchip driver causes build warnings on ARM64. include/soc/nps/common.h: In function 'nps_host_reg_non_cl': include/soc/nps/common.h:148:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] As the driver is only used on ARC, we don't need to see it without COMPILE_TEST elsewhere, and we can avoid the warnings by only building on 32-bit architectures even with CONFIG_COMPILE_TEST.

See http://www.mellanox.com/related-docs/prod_npu/PB_NPS-400.pdf Also present are irqchip and clocksource drivers for NPS as agreed with respective maintainers to go via ARC tree due to an soc header dependency.

* | irqchip: Add per-cpu interrupt partitioning libraryMarc Zyngier2016-05-021-0/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've unfortunately started seeing a situation where percpu interrupts are partitioned in the system: one arbitrary set of CPUs has an interrupt connected to a type of device, while another disjoint set of CPUs has the same interrupt connected to another type of device. This makes it impossible to have a device driver requesting this interrupt using the current percpu-interrupt abstraction, as the same interrupt number is now potentially claimed by at least two drivers, and we forbid interrupt sharing on per-cpu interrupt. A solution to this is to turn things upside down. Let's assume that our system describes all the possible partitions for a given interrupt, and give each of them a unique identifier. It is then possible to create a namespace where the affinity identifier itself is a form of interrupt number. At this point, it becomes easy to implement a set of partitions as a cascaded irqchip, each affinity identifier being the HW irq. This allows us to keep a number of nice properties: - Each partition results in a separate percpu-interrupt (with a restrictied affinity), which keeps drivers happy. - Because the underlying interrupt is still per-cpu, the overhead of the indirection can be kept pretty minimal. - The core code can ignore most of that crap. For that purpose, we implement a small library that deals with some of the boilerplate code, relying on platform-specific drivers to provide a description of the affinity sets and a set of callbacks.

In this hardware, the MSI controller is directly bundled inside the interrupt controller, so we have a single Device Tree node to which multiple IRQ domaines are attached: the wired interrupt domain and the MSI interrupt domain. In order to ensure that they can be differentiated, we have to force the bus_token of the wired interrupt domain to be DOMAIN_BUS_WIRED. The MSI domain bus_token is automatically set to the appropriate value by pci_msi_create_irq_domain().

| * | irqchip/gic: Kconfig the number of instancesLinus Walleij2015-12-181-0/+5
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is currently a hack in the GIC driver making it possible to pass the number of GIC instances from the platform-specific include files and thus override the variable MAX_GIC_NR. With multiplatform deployments, this will not work as we need to get rid of the platform-specific include files. It turns out that this feature is only used by the RealView platform which has a cascaded GIC. So move the configuration to Kconfig and bump to 2 instances if we're building for the RealView. The include file hacks can then be removed. Tested on the ARM PB11MPCore with its cascaded GIC.

* / irqchip/mgigen: Add platform device driver for mbigen deviceMa Jun2015-12-181-0/+8
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mbigen means Message Based Interrupt Generator(MBIGEN). Its a kind of interrupt controller that collects the interrupts from external devices and generate msi interrupt. Mbigen is applied to reduce the number of wire connected interrupts. As the peripherals increasing, the interrupts lines needed is increasing much, especially on the Arm64 server SOC. Therefore, the interrupt pin in GIC is not enough to cover so many peripherals. Mbigen is designed to fix this problem. Mbigen chip locates in ITS or outside of ITS. Mbigen chip hardware structure shows as below: mbigen chip |---------------------|-------------------| mgn_node0 mgn_node1 mgn_node2 | |-------| |-------|------| dev1 dev1 dev2 dev1 dev3 dev4 Each mbigen chip contains several mbigen nodes. External devices can connect to mbigen node through wire connecting way. Because a mbigen node only can support 128 interrupt maximum, depends on the interrupt lines number of devices, a device can connects to one more mbigen nodes. Also, several different devices can connect to a same mbigen node. When devices triggered interrupt,mbigen chip detects and collects the interrupts and generates the MBI interrupts by writing the ITS Translator register. To simplify mbigen driver,I used a new conception--mbigen device. Each mbigen device is initialized as a platform device. Mbigen device presents the parts(register, pin definition etc.) in mbigen chip corresponding to a peripheral device. So from software view, the structure likes below mbigen chip |---------------------|-----------------| mbigen device1 mbigen device2 mbigen device3 | | | dev1 dev2 dev3 Reviewed-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Ma Jun <majun258@huawei.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

| | | | | | | | | | | | | | | | | | | | IMX7D contains a new version of GPC IP block (GPCv2). It has two major functions: power management and wakeup source management. When the system is in WFI (wait for interrupt) mode, the GPC block will be the first block on the platform to be activated and signaled. In normal wait mode during cpu idle, the system can be woken up by any enabled interrupts. In standby or suspend mode, the system can only be wokem up by the pre-defined wakeup sources.
