ARM: dts: am33xx: modify AM33XX_IOPAD for #pinctrl-cells = 2 Modify the AM33XX_IOPAD macro so that it works now that #pinctrl-cells = <2>. The third parameter is just a zero and the pinctrl-single driver will just OR this with the second parameter so it has no actual effect. There are no longer any dts files using this macro (following my patch to am335x-guardian.dts), but this will keep dts files not in mainline from breaking.

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.

ARM: dts: Fix omap3 off mode pull defines We need to also have OFFPULLUDENABLE bit set to use the off mode pull values. Otherwise the line is pulled down internally if no external pull exists. This is has some documentation at: http://processors.wiki.ti.com/index.php/Optimizing_OMAP35x_and_AM/DM37x_OFF_mode_PAD_configuration Note that the value is still glitchy during off mode transitions as documented in spz319f.pdf "Advisory 1.45". It's best to use external pulls instead of relying on the internal ones for off mode and even then anything pulled up will get driven down momentarily on off mode restore for GPIO banks other than bank1.

pinctrl: Move am4372 and dra7 macros to the the SoC header files The <dt-bindings/pinctrl/omap.h> header file defines a set of macros for different SoCs families that falls under the OMAP sub-arch, that allow to define the padconf register physical address instead of the register offset from the padconf base. But the am43xx and dra7xx SoCs families have their own pinctrl header file so the DTS using these SoCs aren't able to use the AM4372_IOPAD() and DRA7XX_CORE_IOPAD() macros since <dt-bindings/pinctrl/omap.h> is not included. Move the macros to the correct header files so can be used by the DTS. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

ARM: dts: Change IOPAD macro's for OMAP4/5 The OMAP4/5 TRMs primarily list address offsets from the padconf physical address (which is not driver base address) and not always the absolute physical address for padconf registers like some other OMAP TRMs. So create a new macro to use this offset and to avoid confusion between different OMAP parts. For more information, see the tables in TRM for named something like "Device Core Control Module Pad Configuration Register Fields" and "Device Wake-Up Control Module Pad Configuration Register Fields" Note that we now also have to update cm-t54 for the fixed up offsets.

ARM: dts: Fix omap serial wake-up when booted with device tree We've had deeper idle states working on omaps for few years now, but only in the legacy mode. When booted with device tree, the wake-up events did not have a chance to work until commit 3e6cee1786a1 (pinctrl: single: Add support for wake-up interrupts) that recently got merged. In addition to that we also needed commit 79d9701559a9 (of/irq: create interrupts-extended property) and 9ec36cafe43b (of/irq: do irq resolution in platform_get_irq) that are now also merged. So let's fix the wake-up events for some selected omaps so devices booted in device tree mode won't just hang if deeper power states are enabled, and so systems can wake up from suspend to the serial port event. Note that there's no longer need to specify the wake-up bit in the pinctrl settings, the request_irq on the wake-up pin takes care of that.

ARM: dts: Add omap specific pinctrl defines to use padconf addresses As we have one to three pinctrl-single instances for each SoC it is a bit confusing to configure the padconf register offset from the base of the padconf register base. Let's add macros that allow using the physical address of the padconf register directly, or in most cases, just the last 16-bits of the address as they are shown in the documentation. Note that most documentation shows two padconf registers for each 32-bit address, so adding 2 to the documentation address is needed for the second padconf register as we treat them as 16-bit registers for omap3+. For example, omap36xx documentation shows sdmmc2_clk at 0x48002158, so we can just use the last 16-bits of that value: pinctrl-single,pins = < OMAP3_CORE1_IOPAD(0x2158, PIN_INPUT_PULLUP | MUX_MODE0) ... >; And we don't need to separately calculate the offset from the 0x2030 base: pinctrl-single,pins = < 0x128 (PIN_INPUT_PULLUP | MUX_MODE0) ... >; Naturally both ways of defining the registers can be used, and I'm not saying we should replace all the existing defines. But it may be handy to use these macros for new entries and when doing other related .dts file clean-up.
