There is an ongoing set of dtc warning fixes and the usual bugfixes, cleanups and added device support. The most interesting bit as usual is support for new machines listed below: - The Allwinner H6 makes its debut with the Pine-H64 board, and we get two new machines based on its older siblings: the H5 based OrangePi Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side, we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2 Zero development board (based on H2). - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972 development board and p2888 CPU module. - The Nuvoton npcm750 is a BMC that was newly added, for now we only support running on the evaluation board. - STmicroelectronics stm32 gains support for the stm32mp157c and two evaluation boards. - The Toradex Colibri board family grows a few members based on the i.MX6ULL variant. - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6 family of chips. - The Phytec phyBOARD Mira is a family of industrial boards based on i.MX6. For now, four models get added. - TI am335x based PDU-001 is an industrial embedded machine used for traffic monitoring - The Aspeed platform now supports running on the BMC on the Qualcomm Centriq 2400 server - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm msm8974 based Galaxy S5 is a rather different phone made by the same company. - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file for the various boards made by Xilinx themselves, as well as the Digilent Zybo Z7. - The ARM Versatile family now supports the "IB2" interface board. - The Renesas H2 based "Stout" and the H3 based Salvator-X are more evaluation boards named after a kind of beer, as most of them are. The r8a77980 (V3H) based "Condor" apparently doesn't follow that tradition. ;-) - ROC-RK3328-CC is a simple developement board from the Libre Computer Project, based on the Rockchips RK3328 SoC - Haiku is another development board plus Qseven module based on Rockchips RK3368 and made by Theobroma Systems" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (701 commits) arm: dts: modify Nuvoton NPCM7xx device tree structure arm: dts: modify Makefile NPCM750 configuration name arm: dts: modify clock binding in NPCM750 device tree arm: dts: modify timer register size in NPCM750 device tree arm: dts: modify UART compatible name in NPCM750 device tree arm: dts: add watchdog device to NPCM750 device tree arm64: dts: uniphier: add ethernet node for PXs3 ARM: dts: uniphier: add pinctrl groups of ethernet for second instance arm: dts: kirkwood*.dts: use SPDX-License-Identifier for board using GPL-2.0+ arm: dts: kirkwood*.dts: use SPDX-License-Identifier for boards using GPL-2.0+/MIT arm: dts: kirkwood*.dts: use SPDX-License-Identifier for boards using GPL-2.0 arm: dts: armada-385-turris-omnia: use SPDX-License-Identifier arm: dts: armada-385-db-ap: use SPDX-License-Identifier arm: dts: armada-388-rd: use SPDX-License-Identifier arm: dts: armada-xp-db-xc3-24g4xg: use SPDX-License-Identifier arm: dts: armada-xp-db-dxbc2: use SPDX-License-Identifier arm: dts: armada-370-db: use SPDX-License-Identifier arm: dts: armada-*.dts: use SPDX-License-Identifier for most of the Armada based board arm: dts: armada-xp-98dx: use SPDX-License-Identifier for prestara 98d SoCs arm: dts: armada-*.dtsi: use SPDX-License-Identifier for most of the Armada SoCs ...
| * arm64: dts: Hi3660: Remove 'CPU_NAP' idle stateLeo Yan2018-03-021-28/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks a lot for Vincent Guittot careful work to find bug for 'CPU_NAP' idle state. At early time, the CPU CA73 CPU_NAP idle state has been supported on Hikey960. Later we found the system has the hang issue and for resolving this issue Hisilicon released new MCU firmware, but unfortunately the new MCU firmware has side effect and results in the CA73 CPU cannot really enter CPU_NAP state and roll back to WFI state. After discussion we cannot see the possibility to enable CA73 CPU_NAP state anymore on Hikey960, based on this conclusion we should remove this state from DT binding.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following dt entries are added: cpus [0-3] (Cortex A53): - capacity-dmips-mhz = <592>; cpus [4-7] (Cortex A73): - capacity-dmips-mhz = <1024>; Those values were obtained by running dhrystone 2.1 on a HiKey960 with the following procedure: - Offline all CPUs but CPU0 (A53) - Set CPU0 frequency to maximum - Run Dhrystone 2.1 for 20 seconds - Offline all CPUs but CPU4 (A73) - set CPU4 frequency to maximum - Run Dhrystone 2.1 for 20 seconds The results are as follows: A53: 129633887 loops A73: 287034147 loops By scaling those values so that the A73s use 1024, we end up with 462 for the A53s. However, they have different maximum frequencies: 1.844GHz for A53s and 2.362GHz for A73s. Thus, we can scale the A53 value to truly represent dmips per MHz, and we end up with 592.

* | License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two clusters on the Hi3660, the first one is Cortex-A53 based and the other one is Cortex-A73 based. These two clusters have different idle states. Thanks to Daniel Lezcano's recent changes, the generic ARM cpuidle driver can now support several clusters with different idle states, thus supporting the big.Little architecture. In addition to the WFI idle state which is the default shallowest state for all ARM cpus, the Hi3660 supports the following states: - CA53 CPUs: - CPU_SLEEP: CPU power off state - CLUSTER_SLEEP_0: Cluster power off state - CA73 CPUs: - CPU_NAP: CPU retention state - CPU_SLEEP: CPU power off state - CLUSTER_SLEEP_1: Cluster power off state This patch adds the idle states description for the Hi3660 to the device tree.

* arm64: dts: hi3660: Add uarts nodesChen Feng2017-06-151-0/+74
| | | | | | | | | | | | | | | | | | | Add nodes uart0 to uart4 and uart6 for hi3660 SoC. Enable uart3 and uart6, disable uart5, in hikey960 board dts. On HiKey960: - UART6 is used as default console, and is wired out through low speed expansion connector. - UART3 has RTS/CTS hardware handshake, and is wired out through low speed expansion connector. - UART5 is not used in commercial launched boards. So disable it. - UART4 is connected to Bluetooth, WL1837.
