License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

irqchip: add basic infrastructure With the recent creation of the drivers/irqchip/ directory, it is desirable to move irq controller drivers here. At the moment, the only driver here is irq-bcm2835, the driver for the irq controller found in the ARM BCM2835 SoC, present in Rasberry Pi systems. This irq controller driver was exporting its initialization function and its irq handling function through a header file in <linux/irqchip/bcm2835.h>. When proposing to also move another irq controller driver in drivers/irqchip, Rob Herring raised the very valid point that moving things to drivers/irqchip was good in order to remove more stuff from arch/arm, but if it means adding gazillions of headers files in include/linux/irqchip/, it would not be very nice. So, upon the suggestion of Rob Herring and Arnd Bergmann, this commit introduces a small infrastructure that defines a central irqchip_init() function in drivers/irqchip/irqchip.c, which is meant to be called as the ->init_irq() callback of ARM platforms. This function calls of_irq_init() with an array of match strings and init functions generated from a special linker section. Note that the irq controller driver initialization function is responsible for setting the global handle_arch_irq() variable, so that ARM platforms no longer have to define the ->handle_irq field in their DT_MACHINE structure. A global header, <linux/irqchip.h> is also added to expose the single irqchip_init() function to the reset of the kernel. A further commit moves the BCM2835 irq controller driver to this new small infrastructure, therefore removing the include/linux/irqchip/ directory.

irqchip: hip04: Enable Hisilicon HiP04 interrupt controller HiP04 GIC is the variate of ARM GICv2. ARM GICv2 supports 8 cores. HiP04 GIC extends to support 16 cores. It results that bit fields in GIC_DIST_TARGET & GIC_DIST_SOFTINT are different from ARM GICv2. And the maximium IRQ is downgrade from 1020 to 510. Since different register offset & bitfields definitation breaks compartible with ARM GICv2, create a new hip04 irq driver. And this driver is derived from irq-gic.c to support the Hisilicon HiP04 interrupt controller, which is similar to the GIC, but deviates at some points. Support for power management, non-banked registers, cascaded GICs (and multiple controllers in general) and bigLittle support has been removed from the GIC driver. Affinity related functions have been adjusted to match the Hisilicon hardware implementation.

irqchip: Add LPC32xx interrupt controller driver The change adds improved support of NXP LPC32xx MIC, SIC1 and SIC2 interrupt controllers. This is a list of new features in comparison to the legacy driver: * irq types are taken from device tree settings, no more need to hardcode them, * old driver is based on irq_domain_add_legacy, which causes problems with handling MIC hardware interrupt 0 produced by SIC1, * there is one driver for MIC, SIC1 and SIC2, no more need to handle them separately, e.g. have two separate handlers for SIC1 and SIC2, * the driver does not have any dependencies on hardcoded register offsets, * the driver is much simpler for maintenance, * SPARSE_IRQS option is supported. Legacy LPC32xx interrupt controller driver was broken since commit 76ba59f8366f ("genirq: Add irq_domain-aware core IRQ handler"), which requires a private interrupt handler, otherwise any SIC1 generated interrupt (mapped to MIC hwirq 0) breaks the kernel with the message "unexpected IRQ trap at vector 00". The change disables compilation of a legacy driver found at arch/arm/mach-lpc32xx/irq.c, the file will be removed in a separate commit.

irqchip: sunxi: Rename sunxi to sun4i During the introduction of the Allwinner SoC platforms, sunxi was initially meant as a generic name for all the variants of the Allwinner SoC. It was ok at the time of the support of only the A10 and A13 that looks pretty much the same, but it's beginning to be troublesome with the future addition of the Allwinner A31 (sun6i) that is quite different, and would introduce some weird logic, where sunxi would actually mean in some case sun4i and sun5i but without sun6i... Moreover, it makes the compatible strings naming scheme not consistent with other architectures, where usually for this kind of compability, we just use the oldest SoC name that has this IP, so let's do just this.

irqchip/gic: Add platform driver for non-root GICs that require RPM Add a platform driver to support non-root GICs that require runtime power-management. Currently, only non-root GICs are supported because the functions, smp_cross_call() and set_handle_irq(), that need to be called for a root controller are located in the __init section and so cannot be called by the platform driver. The GIC platform driver re-uses many functions from the existing GIC driver including some functions to save and restore the GIC context during power transitions. The functions for saving and restoring the GIC context are currently only defined if CONFIG_CPU_PM is enabled and to ensure that these functions are always defined when the platform driver is enabled, a dependency on CONFIG_ARM_GIC_PM (which selects the platform driver) has been added. In order to re-use the private GIC initialisation code, a new public function, gic_of_init_child(), has been added which calls various private functions to initialise the GIC. This is different from the existing gic_of_init() because it only supports non-root GICs (ie. does not call smp_cross_call() is set_handle_irq()) and is not located in the __init section (so can be used by platform drivers). Furthermore, gic_of_init_child() dynamically allocates memory for the GIC chip data which is also different from gic_of_init(). There is no specific suspend handling for GICs registered as platform devices. Non-wakeup interrupts will be disabled by the kernel during late suspend, however, this alone will not power down the GIC if interrupts have been requested and not freed. Therefore, requestors of non-wakeup interrupts will need to free them on entering suspend in order to power-down the GIC.

irqchip: Add per-cpu interrupt partitioning library 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.

irqchip/mgigen: Add platform device driver for mbigen device 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>

It has a single interrupt output for SysWakes, and individual interrupt outputs for each peripheral.

irqchip: Add driver for IXP4xx The IXP4xx (arch/arm/mach-ixp4xx) is an old Intel XScale platform that has very wide deployment and use. As part of modernizing the platform, we need to implement a proper irqchip in the irqchip subsystem. The IXP4xx irqchip is tightly jotted together with the GPIO controller, and whereas in the past we would deal with this complex logic by adding necessarily different code, we can nowadays modernize it using a hierarchical irqchip. The actual IXP4 irqchip is a simple active low level IRQ controller, whereas the GPIO functionality resides in a different memory area and adds edge trigger support for the interrupts. The interrupts from GPIO lines 0..12 are 1:1 mapped to a fixed set of hardware IRQs on this IRQchip, so we expect the child GPIO interrupt controller to go in and allocate descriptors for these interrupts. For the other interrupts, as we do not yet have DT support for this platform, we create a linear irqdomain and then go in and allocate the IRQs that the legacy boards use. This code will be removed on the DT probe path when we add DT support to the platform. We add some translation code for supporting DT translations for the fwnodes, but we leave most of that for later.

The Linux driver does not make use of priorities anyway. For simplicity, there is no aic1-specific logic in the driver beyond setting the priority register, which is necessary for interrupts to work at all. Eventually aic1 will likely be phased out, but it's currently in use in deployments and all released bitstream binaries.

irqchip: Renesas INTC External IRQ pin driver This patch adds a driver for external IRQ pins connected to the INTC block on recent SoCs from Renesas. The INTC hardware block usually contains a rather wide range of features ranging from external IRQ pin handling to legacy interrupt controller support. On older SoCs the INTC is used as a general purpose interrupt controller both for external IRQ pins and on-chip devices. On more recent ARM based SoCs with Cortex-A9 the main interrupt controller is the GIC, but IRQ trigger setup still need to happen in the INTC hardware block. This driver implements the glue code needed to configure IRQ trigger and also handle mask/unmask and demux of external IRQ pins hooked up from the INTC to the GIC. Tested on sh73a0 and r8a7779. The hardware varies quite a bit with SoC model, for instance register width and bitfield widths vary wildly. The driver requires one GIC SPI per external IRQ pin to operate. Each driver instance will handle up to 8 external IRQ pins. The SoCs using this driver are currently mainly used together with regular platform devices so this driver allows configuration via platform data to support things like static interrupt base address. DT support will be added incrementally in the not so distant future.

irqchip/ts4800: Add TS-4800 interrupt controller This commit adds support for the TS-4800 interrupt controller. This controller is instantiated in a companion FPGA, and multiplex interrupts for other FPGA IPs. As this component is external to the SoC, the SoC might need to reserve pins, so this controller is implemented as a platform driver and doesn't use the IRQCHIP_DECLARE construct.

DRIVERS: IRQCHIP: CROSSBAR: Add support for Crossbar IP Some socs have a large number of interrupts requests to service the needs of its many peripherals and subsystems. All of the interrupt lines from the subsystems are not needed at the same time, so they have to be muxed to the irq-controller appropriately. In such places a interrupt controllers are preceded by an CROSSBAR that provides flexibility in muxing the device requests to the controller inputs. This driver takes care a allocating a free irq and then configuring the crossbar IP as a part of the mpu's irqchip callbacks. crossbar_init should be called right before the irqchip_init, so that it is setup to handle the irqchip callbacks.

On VF6xx models, almost all peripherals can be used by either of the two CPU's, the Cortex-A5 or the Cortex-M4. The interrupt router routes the peripheral interrupts to the configured CPU. This IRQ chip driver configures the interrupt router to route the requested interrupt to the CPU the kernel is running on. The driver makes use of the irqdomain hierarchy support. The parent is given by the device tree. This should be one of the two possible parents either ARM GIC or the ARM NVIC interrupt controller. The latter is currently not yet supported. Note that there is no resource control mechnism implemented to avoid concurrent access of the same peripheral. The user needs to make sure to use device trees which assign the peripherals orthogonally. However, this driver warns the user in case the interrupt is already configured for the other CPU. This provides a poor man's resource controller.

IRQCHIP: Add new driver for BCM7038-style level 1 interrupt controllers This is the main peripheral IRQ controller on the BCM7xxx MIPS chips; it has the following characteristics: - 64 to 160+ level IRQs - Atomic set/clear registers - Reasonably predictable register layout (N status words, then N mask status words, then N mask set words, then N mask clear words) - SMP affinity supported on most systems - Typically connected to MIPS IRQ 2,3,2,3 on CPUs 0,1,2,3 This driver registers one IRQ domain and one IRQ chip to cover all instances of the block. Up to 4 instances of the block may appear, as it supports 4-way IRQ affinity on BCM7435. The same block exists on the ARM BCM7xxx chips, but typically the ARM GIC is used instead.

The CIRQ controller is integrated in between MCUSYS( include Cortex-Ax, CCI and GIC ) and interrupt sources as the second level interrupt controller. The external interrupts which outside MCUSYS will feed through CIRQ then bypass to GIC. CIRQ can monitors all edge trigger interupts. When an edge interrupt is triggered, CIRQ can record the status and generate a pulse signal to GIC when flush command executed. When system enters sleep mode, MCUSYS will be turned off to improve power consumption, also GIC is power down. The edge trigger interrupts will be lost in this scenario without CIRQ.

By having Linux configure the ICU, we are more flexible, and we can allocate dynamically the GIC SPI interrupts only for devices that are actually in use.

irqchip: Add support for Layerscape external interrupt lines The LS1021A allows inverting the polarity of six interrupt lines IRQ[0:5] via the scfg_intpcr register, effectively allowing IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_EDGE_FALLING for those. We just need to check the type, set the relevant bit in INTPCR accordingly, and fixup the type argument before calling the GIC's irq_set_type. In fact, the power-on-reset value of the INTPCR register on the LS1021A is so that all six lines have their polarity inverted. Hence any hardware connected to those lines is unusable without this: If the line is indeed active low, the generic GIC code will reject an irq spec with IRQ_TYPE_LEVEL_LOW, while if the line is active high, we must obviously disable the polarity inversion (writing 0 to the relevant bit) before unmasking the interrupt. Some other Layerscape SOCs (LS1043A, LS1046A) have a similar feature, just with a different number of external interrupt lines (and a different POR value for the INTPCR register). This driver should be prepared for supporting those by properly filling out the device tree node. I have the reference manuals for all three boards, but I've only tested the driver on an LS1021A. Unfortunately, the Kconfig symbol ARCH_LAYERSCAPE only exists on arm64, so do as is done for irq-ls-scfg-msi.c: introduce a new symbol which is set when either ARCH_LAYERSCAPE or SOC_LS1021A is set.

drivers/irqchip: Add STM32 external interrupts support The STM32 external interrupt controller consists of edge detectors that generate interrupts requests or wake-up events. Each line can be independently configured as interrupt or wake-up source, and triggers either on rising, falling or both edges. Each line can also be masked independently.

irqchip/qcom: Add IRQ combiner driver Driver for interrupt combiners in the Top-level Control and Status Registers (TCSR) hardware block in Qualcomm Technologies chips. An interrupt combiner in this block combines a set of interrupts by OR'ing the individual interrupt signals into a summary interrupt signal routed to a parent interrupt controller, and provides read- only, 32-bit registers to query the status of individual interrupts. The status bit for IRQ n is bit (n % 32) within register (n / 32) of the given combiner. Thus, each combiner can be described as a set of register offsets and the number of IRQs managed.

irqchip/pdc: Add PDC interrupt controller for QCOM SoCs The Power Domain Controller (PDC) on QTI SoCs like SDM845 houses an interrupt controller along with other domain control functions to handle interrupt related functions like handle falling edge or active low which are not detected at the GIC and handle wakeup interrupts. The interrupt controller is on an always-on domain for the purpose of waking up the processor. Only a subset of the processor's interrupts are routed through the PDC to the GIC. The PDC powers on the processors' domain, when in low power mode and replays pending interrupts so the GIC may wake up the processor.

irqchip: Add driver for Cirrus Logic Madera codecs The Cirrus Logic Madera codecs (Cirrus Logic CS47L35/85/90/91 and WM1840) are highly complex devices containing up to 7 programmable DSPs and many other internal sources of interrupts plus a number of GPIOs that can be used as interrupt inputs. The large number (>150) of internal interrupt sources are managed by an on-board interrupt controller. This driver provides the handling for the interrupt controller. As the codec is accessed via regmap, we can make use of the generic IRQ functionality from regmap to do most of the work. Only around half of the possible interrupt source are currently of interest from the driver so only this subset is defined. Others can be added in future if needed. The KConfig options are not user-configurable because this driver is mandatory so is automatically included when the parent MFD driver is selected.
