2022-07-18soc: fujitsu: Add A64FX diagnostic interrupt driverHitomi Hasegawa1-0/+1
Register the NMI/IRQ corresponding to the A64FX's device definition dedicated to diagnostic interrupts, so that when this interrupt is sent using the BMC, it causes a panic. This can be used to obtain a kernel dump.

2022-05-07ARM: pxa: move plat-pxa to drivers/soc/Arnd Bergmann1-0/+1
There are two drivers in arch/arm/plat-pxa: mfp and ssp. Both of them should ideally not be needed at all, as there are proper subsystems to replace them. OTOH, they are self-contained and can simply be normal SoC drivers, so move them over there to eliminate one more of the plat-* directories.

2022-05-01soc: apple: Always include MakefileSven Peter1-1/+1
We want to allow the code inside drivers/soc/apple to be compiled with COMPILE_TEST but this will currently result in linking errors because ARCH_APPLE is not set and make will never recurse into drivers/soc/apple.

2022-04-30soc: rockchip: Fix compile-testing SoC driversBrian Norris1-1/+1
Similar to commit 7f94b69ece51 ("ARM: ixp4xx: fix compile-testing soc drivers"). drivers/soc/rockchip/Kconfig makes plenty of provision for configuring drivers either for ARCH_ROCKCHIP or for COMPILE_TEST. But drivers/soc/Makefile pulls the rug out from under us, by refusing to build anything if we specified COMPILE_TEST but not ARCH_ROCKCHIP. Currently, I'm not aware of anything that breaks without this patch, but it certainly makes for confusing builds (CONFIG_ROCKCHIP_PM_DOMAINS=y, but we didn't actually compile the driver?) and leaves room for future error (I have pending patches that break confusingly with COMPILE_TEST=y even though their Kconfig dependencies seem correct [1]). Defer to drivers/soc/rockchip/{Makefile,Kconfig} to do the right thing.

2021-01-20ARM: remove zte zx platformArnd Bergmann1-1/+0
The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.

2020-04-03riscv: Add Kendryte K210 SoC supportChristoph Hellwig1-0/+1
Add support for the Kendryte K210 RISC-V SoC. For now, this support only provides a simple sysctl driver allowing to setup the CPU and uart clock. This support is enabled through the new Kconfig option SOC_KENDRYTE and defines the config option CONFIG_K210_SYSCTL to enable the K210 SoC sysctl driver compilation. The sysctl driver also registers an early SoC initialization function allowing enabling the general purpose use of the 2MB of SRAM normally reserved for the SoC AI engine. This initialization function is automatically called before the dt early initialization using the flat dt root node compatible property matching the value "kendryte,k210".

This adds an SoC driver for the Gemini. Currently there is only one thing not fitting into any other framework, and that is the bus arbitration setting. All Gemini vendor trees seem to be setting this register to exactly the same arbitration so we just add a small code snippet to do this at subsys_init() time before any other drivers kick in.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
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.

The goals are to: - Allow precise control over and automatic selection of which (sub)drivers are used for which SoC, - Allow adding support for new SoCs easily, - Allow compile-testing of all (sub)drivers, - Keep driver selection logic in the subsystem-specific Kconfig, independent from the architecture-specific Kconfig (i.e. no "select" from arch/arm64/Kconfig.platforms), to avoid dependencies. This is implemented by: - Introducing Kconfig symbols for all drivers and sub-drivers, - Introducing the Kconfig symbol SOC_RENESAS, which is enabled automatically when building for a Renesas ARM platform, and which enables all required drivers without interaction of the user, based on SoC-specific ARCH_* symbols, - Allowing the user to enable any Kconfig symbol manually if COMPILE_TEST is enabled, - Using the new Kconfig symbols instead of the ARCH_* symbols to control compilation in the Makefile, - Always entering drivers/soc/renesas/ during the build.

This is an almost complete re-write of the previous GPC power gating control code found in the IMX architecture code. It supports both the old and the new DT binding, allowing more domains to be added later and generally makes the driver easier to extend, while keeping compatibility with existing DTBs. As the result, all functionality regarding the power gating controller gets removed from the IMX architecture GPC driver. It keeps only the IRQ controller code in the architecture, as this is closely coupled to the CPU idle implementation.

2016-07-12ARM: ux500: move soc_id driver to drivers/socArnd Bergmann1-0/+1
As the ux500 id code is basically a standalone driver, we can move it out of the arch code into drivers/soc/ux500. This is a user-visible change, as it moves all the devices in sysfs from /sys/devices/soc0/ to /sys/devices/ and leaves the soc0 node as a separate device. Originally the idea was to put all on-chip devices under the soc node, and ux500 was the first platform to have this device, but later platforms almost all didn't follow that pattern, so this makes the platform do the same thing as everyone else. Since the platform is really obsolete now, I am optimistic that nothing will break after moving the devices around. As the SoC driver no longer has access to the private header files, I'm changing the code to instead look up the address of the backupram from devicetree, which is a good idea anyway. Finally, having a separate Kconfig symbol means the driver is now optional and could even be a loadable module rather than always being built-in if we allowed that for soc_device.

2016-04-22soc: renesas: Move pm-rcar to drivers/soc/renesas/rcar-syscGeert Uytterhoeven1-1/+2
Move the pm-rcar driver from arch/arm/mach-shmobile/ to drivers/soc/renesas/, and its header file to include/linux/soc/renesas/, so it can be shared between arm32 (R-Car H1 and Gen2) and arm64 (R-Car Gen3). Rename it to rcar-sysc as it's really a driver for the R-Car System Controller (SYSC). Kill the intermediate PM_RCAR config symbol, as it's not user configurable anymore, and to prepare for SoC-specific make rules. Add the missing #include <linux/types.h> to rcar-sysc.h, which was exposed by different include order.

2016-02-25drivers: soc: Add support for Exynos PMU driverPankaj Dubey1-0/+1
This patch moves Exynos PMU driver implementation from "arm/mach-exynos" to "drivers/soc/samsung". This driver is mainly used for setting misc bits of register from PMU IP of Exynos SoC which will be required to configure before Suspend/Resume. Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC support, there is a need of this PMU driver in driver/* folder. This driver uses existing DT binding information and there should be no functionality change in the supported platforms.
