The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver. Major improvements: - Modernization of the EP93xx driver to use irqdomain and other contemporary concepts. - The ingenic driver has been merged into the Ingenic pin control driver and removed from the GPIO subsystem. - Debounce support in the ftgpio010 driver" * tag 'gpio-v4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (116 commits) gpio: Clarify kerneldoc on gpiochip_set_chained_irqchip() gpio: Remove unused 'irqchip' argument to gpiochip_set_cascaded_irqchip() gpio: Drop parent irq assignment during cascade setup mmc: pwrseq_simple: Fix incorrect handling of GPIO bitmap gpio: fix SNPS_CREG kconfig dependency warning gpiolib: Initialize gdev field before is used gpio: fix kernel-doc after devres.c file rename gpio: fix doc string for devm_gpiochip_add_data() to not talk about irq_chip gpio: syscon: Fix possible NULL ptr usage gpiolib: Show correct direction from the beginning pinctrl: msm: Use init_valid_mask exported function gpiolib: Add init_valid_mask exported function GPIO: add single-register GPIO via CREG driver dt-bindings: Document the Synopsys GPIO via CREG bindings gpio: mockup: use device properties instead of platform_data gpio: Slightly more helpful debugfs gpio: omap: Remove set but not used variable 'dev' gpio: omap: drop omap_gpio_list Accept partial 'gpio-line-names' property. gpio: omap: get rid of the conditional PM runtime calls ...
| * ARM/gpio: ep93xx: build standaloneArnd Bergmann2018-08-291-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As a preparation for multiplatform support, this ensures that the ep93xx gpio driver can be built without any of the platform specific header files. We pass the IRQ numbers as a resource now, and use the virtual mmio base from the already existing resource, rather than relying on the hardwired virtual address from the header file. Some numbers are now hardcoded that came from macros in the past, but for all I can tell, the driver already relied on the specific values.

|/ | | | | | | | | | | | | | | | | | | | | Let's make the raw NAND API consistent by patching all helpers and hooks to take a nand_chip object instead of an mtd_info one or remove the mtd_info object when both are passed. In order to do that, we first need to update the platform_nand_ctrl hooks to take a nand_chip object instead of an mtd_info. We add temporary plat_nand_xxx() wrappers to the do the mtd -> chip conversion, but those will be dropped when patching nand_chip hooks to take a nand_chip object.

We: - Convert the driver to unconditionally grab two GPIOs from the device by index 0 (SDA) and 1 (SCL) which will work fine with device tree and descriptor tables. The existing device trees will continue to work just like before, but without any roundtrip through the global numberspace. - Brutally convert all boardfiles still passing global GPIOs by registering descriptor tables associated with the devices instead so this driver does not need to keep supporting passing any GPIO numbers as platform data. There is no stepwise approach as elegant as this, I strongly prefer this big hammer over any antsteps for this conversion. This way the old GPIO numbers go away and NEVER COME BACK. Special conversion for the different boards utilizing I2C-GPIO: - EP93xx (arch/arm/mach-ep93xx): pretty straight forward as all boards were using the same two GPIO lines, just define these two in a lookup table for "i2c-gpio" and register these along with the device. None of them define any other platform data so just pass NULL as platform data. This platform selects GPIOLIB so all should be smooth. The pins appear on a gpiochip for bank "G" as pins 1 (SDA) and 0 (SCL). - IXP4 (arch/arm/mach-ixp4): descriptor tables have to be registered for each board separately. They all use "IXP4XX_GPIO_CHIP" so it is pretty straight forward. Most board define no other platform data than SCL/SDA so they can drop the #include of <linux/i2c-gpio.h> and assign NULL to platform data. The "goramo_mlr" (Goramo Multilink Router) board is a bit worrisome: it implements its own I2C bit-banging in the board file, and optionally registers an I2C serial port, but claims the same GPIO lines for itself in the board file. This is not going to work: there will be competition for the GPIO lines, so delete the optional extra I2C bus instead, no I2C devices are registered on it anyway, there are just hints that it may contain an EEPROM that may be accessed from userspace. This needs to be fixed up properly by the serial clock using I2C emulation so drop a note in the code. - KS8695 board acs5k (arch/arm/mach-ks8695/board-acs5.c) has some platform data in addition to the pins so it needs to be kept around sans GPIO lines. Its GPIO chip is named "KS8695" and the arch selects GPIOLIB. - PXA boards (arch/arm/mach-pxa/*) use some of the platform data so it needs to be preserved here. The viper board even registers two GPIO I2Cs. The gpiochip is named "gpio-pxa" and the arch selects GPIOLIB. - SA1100 Simpad (arch/arm/mach-sa1100/simpad.c) defines a GPIO I2C bus, and the arch selects GPIOLIB. - Blackfin boards (arch/blackfin/bf533 etc) for these I assume their I2C GPIOs refer to the local gpiochip defined in arch/blackfin/kernel/bfin_gpio.c names "BFIN-GPIO". The arch selects GPIOLIB. The boards get spiked with IF_ENABLED(I2C_GPIO) but that is a side effect of it being like that already (I would just have Kconfig select I2C_GPIO and get rid of them all.) I also delete any platform data set to 0 as it will get that value anyway from static declartions of platform data. - The MIPS selects GPIOLIB and the Alchemy machine is using two local GPIO chips, one of them has a GPIO I2C. We need to adjust the local offset from the global number space here. The ATH79 has a proper GPIO driver in drivers/gpio/gpio-ath79.c and AFAICT the chip is named "ath79-gpio" and the PB44 PCF857x expander spawns from this on GPIO 1 and 0. The latter board only use the platform data to specify pins so it can be cut altogether after this. - The MFD Silicon Motion SM501 is a special case. It dynamically spawns an I2C bus off the MFD using sm501_create_subdev(). We use an approach to dynamically create a machine descriptor table and attach this to the "SM501-LOW" or "SM501-HIGH" gpiochip. We use chip-local offsets to grab the right lines. We can get rid of two local static inline helpers as part of this refactoring.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
