2020-06-10Merge tag 'clk-for-linus' of ↵Linus Torvalds9-456/+2
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This time around we have four lines of diff in the core framework, removing a function that isn't used anymore. Otherwise the main new thing for the common clk framework is that it is selectable in the Kconfig language now. Hopefully this will let clk drivers and clk consumers be testable on more than the architectures that support the clk framework. The goal is to introduce some Kunit tests for the framework. Outside of the core framework we have the usual set of various driver updates and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the largest addition this time around in terms of lines of code. After that the x86 (Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or upcoming SoCs. After that the dirstat shows the usual suspects working on their SoC support by fixing minor bugs, correcting data and converting some of their DT bindings to YAML.

2020-05-27clk: mmp2: Add support for power islandsLubomir Rintel1-0/+2
Apart from the clocks and resets, the PMU hardware also controls power to peripherals that are on separate power islands. On MMP2, that's the GC860 GPU and the SSPA audio interface, while on MMP3 also the camera interface is on a separate island, along with the pair of GC2000 and GC300 GPUs and the SSPA.

Support for Marvell MMP ARMv5 platforms depends on ARCH_MULTI_V5, and thus on ARCH_MULTIPLATFORM. As the latter selects COMMON_CLK, there is no need for MACH_MMP_DT to select COMMON_CLK.

2020-05-12ARM: mmp: Remove legacy clk codeStephen Boyd8-456/+0
Remove all the legacy clk code that supports a non-common clk framework implementation of 'struct clk' in mach-mmp. This code doesn't look to be compiled anymore given that the MMP is fully supported in the multi-platform config via ARCH_MULTIPLATFORM as of commit 377524dc4d77 ("ARM: mmp: move into ARCH_MULTIPLATFORM"). The ARCH_MULTIPLATFORM config selects COMMON_CLK and therefore the Makefile rule can never actually compile the code in these files.

2020-03-27ARM: mmp: replace setup_irq() by request_irq()afzal mohammed1-8/+3
request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq().

2019-02-06regulator: fixed/gpio: Pull inversion/OD into gpiolibLinus Walleij1-1/+0
This pushes the handling of inversion semantics and open drain settings to the GPIO descriptor and gpiolib. All affected board files are also augmented. This is especially nice since we don't have to have any confusing flags passed around to the left and right littering the fixed and GPIO regulator drivers and the regulator core. It is all just very straight-forward: the core asks the GPIO line to be asserted or deasserted and gpiolib deals with the rest depending on how the platform is configured: if the line is active low, it deals with that, if the line is open drain, it deals with that too.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM Device-tree updates from Olof Johansson: "As usual, this is where the bulk of our changes end up landing each merge window. The individual updates are too many to enumerate, many many platforms have seen additions of device descriptions such that they are functionally more complete (in fact, this is often the bulk of updates we see). Instead I've mostly focused on highlighting the new platforms below as they are introduced. Sometimes the introduction is of mostly a fragment, that later gets filled in on later releases, and in some cases it's near-complete platform support. The latter is more common for derivative platforms that already has similar support in-tree. Two SoCs are slight outliers from the usual range of additions. Allwinner support for F1C100s, a quite old SoC (ARMv5-based) shipping in the Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A, a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at infrastructure/networking. TI updates stick out in the diff stats too, in particular because they have moved the description of their L4 on-chip interconnect to devicetree, which opens up for removal of even more of their platform-specific 'hwmod' description tables over the next few releases.

Moreover, it is only available with CONFIG_CPU_MMP2 and thus doesn't work on DT-based MMP2 machines. Enable it on CONFIG_MACH_MMP2_DT too.

2018-09-17regulator: fixed: Convert to use GPIO descriptor onlyLinus Walleij1-1/+11
As we augmented the regulator core to accept a GPIO descriptor instead of a GPIO number, we can augment the fixed GPIO regulator to look up and pass that descriptor directly from device tree or board GPIO descriptor look up tables. Some boards just auto-enumerate their fixed regulator platform devices and I have assumed they get names like "fixed-regulator.0" but it's pretty hard to guess this. I need some testing from board maintainers to be sure. Other boards are straight forward, using just plain "fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the device ID. It seems the da9055 and da9211 has never got around to actually passing any enable gpio into its platform data (not the in-tree code anyway) so we can just decide to simply pass a descriptor instead. The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named "*_dummy_supply_device" while it is a very real device backed by a GPIO line. There is nothing dummy about it at all, so I renamed it with the infix *_regulator_* as part of this patch set. Intel MID portions tested by Andy.

2018-03-02mtd: nand: remove useless fields from pxa3xx NAND platform dataMiquel Raynal2-8/+3
The "enable arbiter" bit is available only for pxa3xx based platforms but it was experimentally shown that even if this bit is reserved, some Marvell platforms (64-bit) actually need it to be set. The driver always set this bit regardless of this property, which is harmless. Then this property is not needed. The "num_cs" field is always 1 and for a good reason, the old driver (pxa3xx_nand.c) could only handle one. The new driver that replaces it (marvell_nand.c) can handle more, but better use device tree for such description. As there is only one available chip select, there is no need for an array of partitions neither an array of partition numbers.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman15-0/+15
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.
