2018-02-22arm64: dts: Remove leading 0x and 0s from bindings notationMathieu Malaterre1-1/+1
Improve the DTS files by removing all the leading "0x" and zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" and Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -E -i -e "s/@0x([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" -e "s/@0+([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" {} + For simplicity, two sed expressions were used to solve each warnings separately. To make the regex expression more robust a few other issues were resolved, namely setting unit-address to lower case, and adding a whitespace before the the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions This is a follow up to commit 4c9847b7375a ("dt-bindings: Remove leading 0x from bindings notation") Reported-by: David Daney <ddaney@caviumnetworks.com> Suggested-by: Rob Herring <robh@kernel.org> Signed-off-by: Mathieu Malaterre <malat@debian.org> Acked-by: Matthias Brugger <matthias.bgg@gmail.com> Acked-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

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.

2017-11-09kbuild: handle dtb-y and CONFIG_OF_ALL_DTBS natively in Makefile.libMasahiro Yamada1-3/+0
If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile. It could be a race problem when building DTBS in parallel. Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor sub-directories, so this broke when Broadcom added one more hierarchy in arch/arm64/boot/dts/broadcom/<soc>/. One idea to fix the issues in a clean way is to move DTB handling to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y natively, so it should not hurt to do so. Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is enabled. All clutter things in Makefiles go away. As a bonus clean-up, I also removed dts-dirs. Just use subdir-y directly to traverse sub-directories.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman7-0/+7
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 hi6220-HiKey board started to name GPIO lines for 96boards, using just the plain names "GPIO-A" etc from the 96boards specification. Poplar started to use an arbitrary "LS-GPIO-A" (etc) prefix that is not part of the 96boards specification. As the former notation arrived first, and we need consistency among 96board, rectify the Poplar board to use this too. This is important for userspace that wants to look up GPIO names from these strings.

"GPIO-A" through "GPIO-L" are the most important since they give users a handle to look up the standard 96boards GPIOs from the GPIO character device. The rest of the names are more informational, nice debug information for "lsgpio" so you can see that the right line is taken for the right function in the kernel for example.

Due system has another CPU and one MCU, all of them transfer the trace data through trace bus (ATB) to SoC funnel; the SoC funnel is connected to Embedded Trace FIFO (ETF) with 8KB buffer; an non-configurable replicator is used to output trace data for two sinks, one is Embedded Trace Route (ETR) so trace data can be saved into DRAM, another is Trace Port Interface Unit (TPIU) for capturing trace data by external debugger.

2017-08-16arm64: dts: hi3660: enable idle statesLeo Yan1-0/+63
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.

2017-08-16arm64: dts: hi6220: improve g-tx-fifo-size setting for usb deviceShawn Guo1-1/+2
The current usb device g-tx-fifo-size setting in DT causes two problems for kernel driver. 1. On hi6220, there are 15 tx_fifo dedicated for all EPs except EP0, while DT only provides tx_fifo settings for 6 EPs. It results in the following annoying complaints from kernel. [ 4.451623] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[7]=0 [ 4.461303] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[8]=0 [ 4.470969] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[9]=0 [ 4.480632] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[10]=0 [ 4.490385] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[11]=0 [ 4.500140] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[12]=0 [ 4.509892] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[13]=0 [ 4.519646] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[14]=0 [ 4.529399] dwc2 f72c0000.usb: dwc2_check_param_tx_fifo_sizes: Invalid parameter g_tx_fifo_size[15]=0 [ 4.539244] dwc2 f72c0000.usb: EPs: 16, dedicated fifos, 1920 entries in SPRAM Besides of that, the total 1920 fifo entries isn't fully utilized. Endpoint Info Control block consumes 128 entries, g-rx-fifo-size is 512, and g-np-tx-fifo-size is 128. So the fifi entries available for tx_fifo is: 1920 - 128 - 512 - 128 = 1152. Considering that the minimal valid tx_fifo size for each EP is 16, it should be reasonable to allocate 1152 entries as: 128 x 8 + 16 x 7 = 1136 (only 16 entries unused). With this new setting, we can get more EPs to use while removing the above warning messages in the meantime. 2. Another consequence of above invalid g_tx_fifo_size parameter is that kernel driver will use values read from hardware register as the fall-back. The value is 2048 for each EP fifo. That's obviously invalid either, because even fifo entries for one EP exceeds the total entries 1920. That's why we see the following fat warning from function dwc2_hsotg_init_fifo(). The new g-tx-fifo-size settings help to remove the warning as well.

For the first time I can remember, this is actually larger than the corresponding branch for 32-bit platforms overall, though that has more individual changes. A significant portion this time is due to added machine support: - Initial support for the Realtek RTD1295 SoC, along with the Zidoo X9S set-top-box - Initial support for Actions Semi S900 and the Bubblegum-96 single-board-cёmputer. - Rockchips support for the rk3399-Firefly single-board-computer gets added, this one stands out for being relatively fast, affordable and well₋supported, compared to many boards that only fall into one or two of the above categories. - Mediatek gains support for the mt6797 mobile-phone SoC platform and corresponding evaluation board. - Amlogic board support gets added for the NanoPi K2 and S905x LibreTech CC single-board computers and the R-Box Pro set-top-box - Allwinner board support gets added for the OrangePi Win, Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single board computers and the SoPine system-on-module. - Renesas board support for Salvator-XS and H3ULCB automotive development systems. - Socionext Uniphier board support for LD11-global and LD20-global, whatever those may be. - Broadcom adds support for the new Stingray communication processor in its iProc family, along with two reference boards.

2017-06-15arm64: dts: hi3660: Add uarts nodesChen Feng2-3/+91
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.
