In certain cases it is possible that the timekeeping has been suspended already when attempting to disable/enable a clkctrl clock. This will happen at least on am43xx platform when attempting to enable / disable the clockevent source itself, burping out a warning from timekeeping core. The sequence of events leading to this: -> timekeeping_suspend() -> clockevents_suspend() -> omap_clkevt_idle() -> omap_hwmod_idle() -> _omap4_clkctrl_clk_disable() -> _omap4_is_timeout() Avoid the issue by checking if the timekeeping is suspended and using the fallback udelay approach for checking timeouts.

2017-11-17Merge tag 'clk-for-linus' of ↵Linus Torvalds3-8/+3
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have two changes to the core framework this time around. The first being a large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis. Summary: Core: - runtime PM support for clk providers - devm API for of_clk_add_hw_provider() New Drivers: - Mediatek MT2712 and MT7622 - Renesas R-Car V3M SoC Updates: - runtime PM support for Samsung exynos5433/exynos4412 providers - removal of clkdev aliases on Samsung SoCs - convert clk-gpio to use gpio descriptors - various driver cleanups to match kernel coding style - Amlogic Video Processing Unit VPU and VAPB clks - sigma-delta modulation for Allwinner audio PLLs - Allwinner A83t Display clks - support for the second display unit clock on Renesas RZ/G1E - suspend/resume support for Renesas R-Car Gen3 CPG/MSSR - new clock ids for Rockchip rk3188 and rk3368 SoCs - various 'const' markings on clk_ops structures - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (137 commits) clk: stm32h7: fix test of clock config clk: pxa: fix building on older compilers clk: sunxi-ng: a83t: Fix i2c buses bits clk: ti: dra7-atl-clock: fix child-node lookups clk: qcom: common: fix legacy board-clock registration clk: uniphier: fix DAPLL2 clock rate of Pro5 clk: uniphier: fix parent of miodmac clock data clk: hi3798cv200: correct parent mux clock for 'clk_sdio0_ciu' clk: hisilicon: Delete an error message for a failed memory allocation in hisi_register_clkgate_sep() clk: hi3660: fix incorrect uart3 clock freqency clk: kona-setup: Delete error messages for failed memory allocations ARC: clk: fix spelling mistake: "configurarion" -> "configuration" clk: cdce925: remove redundant check for non-null parent_name clk: versatile: Improve sizeof() usage clk: versatile: Delete error messages for failed memory allocations clk: ux500: Improve sizeof() usage clk: ux500: Delete error messages for failed memory allocations clk: spear: Delete error messages for failed memory allocations clk: ti: Delete error messages for failed memory allocations clk: mmp: Adjust checks for NULL pointers ...

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+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.

2017-03-08clk: ti: convert to use proper register definition for all accessesTero Kristo16-276/+225
Currently, TI clock driver uses an encapsulated struct that is cast into a void pointer to store all register addresses. This can be considered as rather nasty hackery, and prevents from expanding the register address field also. Instead, replace all the code to use proper struct in place for this, which contains all the previously used data. This patch is rather large as it is touching multiple files, but this can't be split up as we need to avoid any boot breakage.

This can be used from the divider itself, and also from the clkctrl clocks once this is introduced. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: divider: convert TI divider clock to use its own data representationTero Kristo3-13/+24
Instead of using the generic clock driver data struct, use one internal for the TI clock driver itself. This allows modifying the register access parts in subsequent patch. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: mux: convert TI mux clock to use its internal data representationTero Kristo2-5/+16
Instead of using the generic clock driver data struct, use one internal for the TI clock driver itself. This allows modifying the register access parts in subsequent patch. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: drop unnecessary MEMMAP_ADDRESSING flagTero Kristo4-7/+1
This has been superceded by the usage of ti_clk_ll_ops for now. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: omap4: cleanup unnecessary clock aliasesTero Kristo1-186/+2
Cleanup any unnecessary DT_CLK() alias entries from the OMAP4 clock file. Most of these are now handled dynamically by the driver code. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: enforce const types on string arraysTero Kristo3-6/+6
Constant string arrays should use const char * const instead of just const char *. Change the implementations using these to proper type. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: move omap2_init_clk_clkdm under TI clock driverTero Kristo2-0/+31
This is not needed outside the driver, so move it inside it and remove the prototype from the public header also. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: use automatic clock alias generation frameworkTero Kristo10-15/+49
Generate clock aliases automatically for all TI clock drivers. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: add API for creating aliases automatically for simple clock typesTero Kristo2-0/+27
This API generates clock aliases automatically for simple clock types (fixed-clock, fixed-factor-clock), so that we don't need to add the data for these statically into tables. Shall be called from the SoC specific clock init. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2017-03-08clk: ti: add support for automatic clock alias generationTero Kristo2-0/+67
Large portions of the OMAP framework still depend on the support of having clock aliases in place, so add support functions for generating these automatically. Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
