2017-11-03Update MIPS email addressesPaul Burton5-5/+5
MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list. An entry is added to .mailmap for each person such that get_maintainer.pl will report the new addresses rather than @imgtec.com addresses which will soon be dead. Instances of the affected addresses throughout the tree are then mechanically replaced with the new @mips.com address.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman45-0/+45
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.

Commit 6edfa11cb396 ("clk: samsung: Add enable/disable operation for PLL36XX clocks") added enable/disable operations to PLL clocks. Prior that VPLL and EPPL clocks were always enabled because the enable bit was never touched. Those clocks have to be enabled during suspend/resume cycle, because otherwise board fails to enter sleep mode. This patch enables them unconditionally before entering system suspend state. System restore function will set them to the previous state saved in the register cache done before that unconditional enable.

2017-09-01clk: si5351: fix PLL resetRussell King1-7/+5
Changing the audio sample rate on the SolidRun Cubox disrupts the video output. The Si5351 provides both the video clock (using PLLA on output 0) and the audio clock (using PLLB on output 2). When the rate of clock output 2 is changed, it reconfigures PLLB, which results in both PLLA and PLLB being reset. The reset of PLLA causes clock output 0 to be disrupted, thereby causing a loss of sync by the attached display device. Hence, each time the audio sample rate changes (eg, when a video player starts up, or when starting to play music) the video display momentarily blanks while the Si5351 settles down. Prior to the commit below, this behaviour did not happen. Fix this by only resetting only the PLL which has been changed.

2017-09-01clk: at91: clk-generated: make gclk determine audio_pll rateQuentin Schulz1-6/+57
This allows gclk to determine audio_pll rate and set the parent rate accordingly. However, there are multiple children clocks that could technically change the rate of audio_pll (via gck). With the rate locking, the first consumer to enable the clock will be the one definitely setting the rate of the clock. Since audio IPs are most likely to request the same rate, we enforce that the only clks able to modify gck rate are those of audio IPs. To remain consistent, we deny other clocks to be children of audio_pll.

2017-09-01clk: at91: add audio pll clock driversQuentin Schulz2-0/+537
This new clock driver set allows to have a fractional divided clock that would generate a precise clock particularly suitable for audio applications. The main audio pll clock has two children clocks: one that is connected to the PMC, the other that can directly drive a pad. As these two routes have different enable bits and different dividers and divider formulas, they are handled by two different drivers. Each of them could modify the rate of the main audio pll parent. The main audio pll clock can output 620MHz to 700MHz.

2017-09-01clk: at91: clk-generated: remove useless divisor loopQuentin Schulz1-13/+12
The driver requests the current clk rate of each of its parent clocks to decide whether a clock rate is suitable or not. It does not request determine_rate from a parent clock which could request a rate change in parent clock (i.e. there is no parent rate propagation). We know the rate we want (passed along req argument of the function) and the parent clock rate, thus we know the closest rounded divisor, we don't need to iterate over the available divisors to find the best one for a given clock.

2017-08-30ARC: clk: introduce HSDK pll driverEugeniy Paltsev3-0/+439
HSDK board manages its clocks using various PLLs. These PLL have same dividers and corresponding control registers mapped to different addresses. So we add one common driver for such PLLs. Each PLL on HSDK board consists of three dividers: IDIV, FBDIV and ODIV. Output clock value is managed using these dividers. We add pre-defined tables with supported rate values and appropriate configurations of IDIV, FBDIV and ODIV for each value. As of today we add support for PLLs that generate clock for the HSDK arc cpus, system, ddr, AXI tunnel and hdmi. By this patch we add support for several plls (arc cpus pll and others), so we had to use two different init types: CLK_OF_DECLARE for arc cpus pll and regular probing for others plls.
