ARM: SoC: late updates for linux-5.1
Here are two branches that came relatively late during the linux-5.0
development cycle and have dependencies on the other branches:
- On the TI OMAP platform, the CPSW Ethernet PHY mode selection driver
is being replaced, this puts the final pieces in place
- On the DaVinci platform, the interrupt handling code in arch/arm
gets moved into a regular device driver in drivers/irqchip.
Since they both had some time in linux-next after the 5.0-rc8
release, I'm sending them along with the other updates.

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.

irqchip/irq-mvebu-sei: Add new driver for Marvell SEI
This is a cascaded interrupt controller in the AP806 GIC that collapses
SEIs (System Error Interrupt) coming from the AP and the CPs (through
the ICU).
The SEI handles up to 64 interrupts. The first 21 interrupts are wired
from the AP. The next 43 interrupts are from the CPs and are triggered
through MSI messages. To handle this complexity, the driver has to
declare to the upper layer: one IRQ domain for the wired interrupts,
one IRQ domain for the MSIs; and acts as a MSI controller ('parent')
by declaring an MSI domain.

Staging/IIO patches for 4.17-rc1

We deleted more lines than we added again (27k added vs. 91k remvoed), thanks to finally being able to delete the IRDA drivers and networking code. We also deleted the ccree crypto driver, but that's coming back in through the crypto tree to you, in a much cleaned-up form. Added this round is at lot of "mt7621" device support, which is for an embedded device that Neil Brown cares about, and of course a handful of new IIO drivers as well. And finally, the fsl-mc core code moved out of the staging tree to the "real" part of the kernel, which is nice to see happen as well.

arch: remove obsolete architecture ports
This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers. I have been working with the (former) maintainers for each one to ensure that my interpretation was right and the code is definitely unused in mainline kernels. Many had fond memories of working on the respective ports to start with and getting them included in upstream, but also saw no point in keeping the port alive without any users. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees. The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/. Unlike the original plans, I'm not marking any ports as deprecated but remove them all at once after I made sure that they are all unused. Some architectures (notably tile, mn10300, and blackfin) are still being shipped in products with old kernels, but those products will never be updated to newer kernel releases. After this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer. At least in case of hexagon, this will only be llvm, not gcc. - openrisc, risc-v and nds32 are still in the process of finishing their support or getting it added to mainline gcc in the first place. They all have patched gcc-7.3 ports that work to some degree, but complete upstream support won't happen before gcc-8.1. Csky posted their first kernel patch set last week, their situation will be similar. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJawdL2AAoJEGCrR//JCVInuH0P/RJAZh1nTD+TR34ZhJq2TBoo PgygwDU7Z2+tQVU+EZ453Gywz9/NMRFk1RWAZqrLix4ZtyIMvC6A1qfT2yH1Y7Fb Qh6tccQeLe4ezq5u4S/46R/fQXu3Txr92yVwzJJUuPyU0arF9rv5MmI8e6p7L1en yb74kSEaCe+/eMlsEj1Cc1dgthDNXGKIURHkRsILoweysCpesjiTg4qDcL+yTibV FP2wjVbniKESMKS6qL71tiT5sexvLsLwMNcGiHPj94qCIQuI7DLhLdBVsL5Su6gI sbtgv0dsq4auRYAbQdMaH1hFvu6WptsuttIbOMnz2Yegi2z28H8uVXkbk2WVLbqG ZESUwutGh8MzOL2RJ4jyyQq5sfo++CRGlfKjr6ImZRv03dv0pe/W85062cK5cKNs cgDDJjGRorOXW7dyU6jG2gRqODOQBObIv3w5efdq5OgzOWlbI4EC+Y5u1Z0JF/76 pSwtGXA6YhwC+9LLAlnVTHG+yOwuLmAICgoKcTbzTVDKA2YQZG/cYuQfI5S1wD8e X6urPx3Md2GCwLXQ9mzKBzKZUpu/Tuhx0NvwF4qVxy6x1PELjn68zuP7abDHr46r 57/09ooVN+iXXnEGMtQVS/OPvYHSa2NgTSZz6Y86lCRbZmUOOlK31RDNlMvYNA+s 3iIVHovno/JuJnTOE8LY =fQ8z -----END PGP SIGNATURE----- Merge tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pul removal of obsolete architecture ports from Arnd Bergmann: "This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers.

[ See the new nds32 port merged in the previous commit for the next generation of "one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem" - Linus ] The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/. Unlike the original plans, I'm not marking any ports as deprecated but remove them all at once after I made sure that they are all unused. Some architectures (notably tile, mn10300, and blackfin) are still being shipped in products with old kernels, but those products will never be updated to newer kernel releases. After this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer. At least in case of hexagon, this will only be llvm, not gcc. - openrisc, risc-v and nds32 are still in the process of finishing their support or getting it added to mainline gcc in the first place. They all have patched gcc-7.3 ports that work to some degree, but complete upstream support won't happen before gcc-8.1. Csky posted their first kernel patch set last week, their situation will be similar [ Palmer Dabbelt points out that RISC-V support is in mainline gcc since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]" This really says it all: 2498 files changed, 95 insertions(+), 467668 deletions(-) * tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (74 commits) MAINTAINERS: UNICORE32: Change email account staging: iio: remove iio-trig-bfin-timer driver tty: hvc: remove tile driver tty: remove bfin_jtag_comm and hvc_bfin_jtag drivers serial: remove tile uart driver serial: remove m32r_sio driver serial: remove blackfin drivers serial: remove cris/etrax uart drivers usb: Remove Blackfin references in USB support usb: isp1362: remove blackfin arch glue usb: musb: remove blackfin port usb: host: remove tilegx platform glue pwm: remove pwm-bfin driver i2c: remove bfin-twi driver spi: remove blackfin related host drivers watchdog: remove bfin_wdt driver can: remove bfin_can driver mmc: remove bfin_sdh driver input: misc: remove blackfin rotary driver input: keyboard: remove bf54x driver ... |

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.

"A rather large update for the interrupt core code and the irq chip drivers:
- Add a new bitmap matrix allocator and supporting changes, which is
used to replace the x86 vector allocator which comes with separate

recently added property of managed interrupts proper and allows to
switch to a best effort vector reservation scheme, which addresses
problems with vector exhaustion.
- A large update to the ARM GIC-V3-ITS driver adding support for
range selectors.
- New interrupt controllers:
- Meson and Meson8 GPIO
- BCM7271 L2
- Socionext EXIU
If you expected that this will stop at some point, I have to
disappoint you. There are new ones posted already. Sigh!
- STM32 interrupt controller support for new platforms.

- Update the or1ksim dts to use stdout-path
OpenRISC SMP support details:
- First the "use shadow registers" and "define CPU_BIG_ENDIAN as true"

- The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
qrwlocks" add the SMP locking infrastructure as needed. Using the
qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
original spinlocks implementation.
- The "support for ompic" adds a new irqchip device which is used for
IPI communication to support SMP.
- The "initial SMP support" adds smp.c and makes changes to all of the
necessary data-structures to be per-cpu.
- The remaining patches are bug fixes and debug helpers which I wanted
to keep separate from the "initial SMP support" in order to allow them
to be reviewed on their own. This includes:
- add cacheflush support to fix icache aliasing
- fix initial preempt state for secondary cpu tasks
- sleep instead of spin on secondary wait
- support framepointers and STACKTRACE_SUPPORT
- enable LOCKDEP_SUPPORT and irqflags tracing
- timer sync: Add tick timer sync logic
- fix possible deadlock in timer sync, pointed out by mips guys
Note: the irqchip patch was reviewed with Marc and we agreed to push it

irqchip/gic-v3-its: Remove artificial dependency on PCI
The GICv3 ITS doesn't really depend on PCI. Only the PCI/MSI
part of it does, and there is no reason not to blow away most
of the irqchip stack because PCI is not selected (though not
selecting PCI seem to be asking for punishment, but hey...).
So let's split the PCI-specific part from the ITS in the Kconfig
file, and let's make that part depend on PCI. Architecture specific
hacks (arch/arm{,64}/Kconfig) will be addressed in a separate patch.

This IPI device, the ompic, is the only external device required for enabling SMP on OpenRISC.

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/irq-mvebu-icu: Add new driver for Marvell ICU
The Marvell ICU unit is found in the CP110 block of the Marvell Armada 7K and 8K SoCs. It collects the wired interrupts of the devices located in the CP110 and turns them into SPI interrupts in the GIC located in the AP806 side of the SoC, by using a memory transaction. Until now, the ICU was configured in a static fashion by the firmware, and Linux was relying on this static configuration. 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. The driver was initially written by Hanna Hawa <hannah@marvell.com>.

irqchip/aspeed-i2c-ic: Add I2C IRQ controller for Aspeed
The Aspeed 24XX/25XX chips share a single hardware interrupt across 14 separate I2C busses. This adds a dummy irqchip which maps the single hardware interrupt to software interrupts for each of the busses.

irqchip: Add Mediatek mtk-cirq driver
In Mediatek SOCs, the CIRQ is a low power interrupt controller designed to works outside MCUSYS which comprises with Cortex-Ax cores,CCI and GIC. 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. This commit provides the CIRQ irqchip implement. Signed-off-by: Youlin Pei <youlin.pei@mediatek.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> |

irqchip/faraday: Replace moxa with ftintc010
The Moxa Art interrupt controller is very very likely just an instance of the Faraday FTINTC010 interrupt controller from Faraday Technology. An indication would be its close association with the FA526 ARM core and the fact that the register layout is the same. The implementation in irq-moxart.c can probably be right off replaced with the irq-ftintc010.c driver by adding a compatible string, selecting this irqchip from the machine and run. As a bonus we have an irqchip driver supporting high/low and rising/falling edges for the Moxa Art, and shared code with the Gemini platform.

irqchip/gemini: Refactor Gemini driver to reflect Faraday origin
The Gemini irqchip turns out to be a standard IP component from Faraday Technology named FTINTC010 after some research and new information. - Rename the driver and all symbols to reflect the new information. - Add the new compatible string "faraday,ftintc010" - Create a Kconfig symbol CONFIG_FARADAY_FTINTC010 so that SoCs using this interrupt controller can easily select and reuse it instead of hardwiring it to ARCH_GEMINI I have created a separate patch to select the new Kconfig symbol from the Gemini machine, which will be merged through the ARM SoC tree.

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.

ARM: SoC cleanups for v4.9
The cleanups for v4.9 are a little larger that usual, but thankfully
that is almost exclusively due to removing a significant number of
files that have become obsolete after the still ongoing conversion
of old board files to devicetree.
- for mach-omap2, which is still the largest platform in arch/arm/,
the conversion to DT is finally complete after the Nokia N900 is
now fully supported there, along with the omap3 LDP, and we can
remove those two board files.
If no regressions are found, another large cleanup for the platform
will happen as a follow-up, removing dead code and restructuring
the platform based on being DT-only.
- In mach-imx, similar work is ongoing, but has not come that far.
This time, we remove the obsolete board file for the i.MX1
generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only.
The remaining board files are for i.MX2 and i.MX3 machines
based on old ARM926 or ARM1136 cores that should work with DT
in principle.
- realview has just been converted from board files to DT, and a lot
of code gets removed in the process. This is the last
ARM/Keil/Versatile derived platform that was still using board
files, the other ones being integrator, versatile and vexpress.
We can probably merge the remaining code into a single directory
in the near future.
- clps711x had completed the conversion in v4.8, but we accidentally
left the files in place that should have been deleted then.
Conflicts: two files deleted here have been modified upstream,
the changes can be discarded.

irqchip/mvebu-pic: New driver for Marvell Armada 7K/8K PIC
The Marvell Armada 7K/8K integrates a secondary interrupt controller very originally named "PIC". It is connected to the main GIC via a PPI. Amongst other things, this PIC is used for the ARM PMU. This commit adds a simple irqchip driver for this interrupt controller. Since this interrupt controller is not needed early at boot time, we make the driver a proper platform driver rather than use the IRQCHIP_DECLARE() mechanism.

ARM: realview: imply device tree boot
This reduces the Kconfig for the RealView by assuming we are always booting from the device tree, and removing all the uses of CONFIG_REALVIEW_DT and replacing with CONFIG_ARCH_REALVIEW. Further: - Drop REALVIEW_HIGH_PHYS_OFFSET: we don't use this with device tree. - Drop the REALVIEW_EB_ARM11MP_REVB option: we now handle this by simply using another device tree. - Drop the PB1176 secure flash option: this is defined in the PB1176 device tree but marked as "disabled", so users who want to use it can simply enable it in the device tree and go hacking around.

irqchip/jcore-aic: Add J-Core AIC driver
There are two versions of the J-Core interrupt controller in use, aic1 which generates interrupts with programmable priorities, but only supports 8 irq lines and maps them to cpu traps in the range 17 to 24, and aic2 which uses traps in the range 64-127 and supports up to 128 irqs, with priorities dependent on the interrupt number. 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.
