2018-01-22ARM: omap: hwmod: fix section mismatch warningsArnd Bergmann
Older compilers choose not to inline _setup_clkctrl_provider(), leading to a harmless warning: WARNING: vmlinux.o(.text+0x27b34): Section mismatch in reference from the function _setup_clkctrl_provider() to the function .init.text:memblock_virt_alloc_try_nid() The function _setup_clkctrl_provider() references the function __init memblock_virt_alloc_try_nid(). This is often because _setup_clkctrl_provider lacks a __init annotation or the annotation of memblock_virt_alloc_try_nid is wrong. This annotates it as __init as well, which lets the linker see that it is actually correct. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2017-12-21bus: ti-sysc: Make omap_hwmod_sysc_fields into sysc_regbits platform dataTony Lindgren
We want to be able to configure hwmod sysc data from ti-sysc driver using platform data callbacks. So let's make struct omap_hwmod_sysc_fields into struct sysc_data and have it available for both ti-sysc driver and hwmod code. Note that we can make it use s8 instead of u8 as the hwmod code uses the feature flags to check for this field. However, for ti-sysc we can use -ENODEV to indicate a feature is not supported in the hardware and can simplify the code that way. And let's add also emufree_shift as the dts files will be describing the hardware for the SYSCONFIG register capbilities mask.

This is not present in any of the other power domains. Hence remove the generic am33xx_pwrdm_read_prev_pwrst hook which wrongly reads the reserved bit fields for all the other power domains.

2017-11-28ARM: OMAP2+: Fix SRAM virt to phys translation for save_secure_ram_contextTony Lindgren
With the CMA changes from Joonsoo Kim <iamjoonsoo.kim@lge.com>, it was noticed that n900 stopped booting. After investigating it turned out that n900 save_secure_ram_context does some whacky virtual to physical address translation for the SRAM data address. As we now only have minimal parts of omap3 idle code copied to SRAM, running save_secure_ram_context() in SRAM is not needed. It only gets called on PM init. And it seems there's no need to ever call this from SRAM idle code. So let's just keep save_secure_ram_context() in DDR, and pass it the physical address of the parameters. We can do everything else in omap-secure.c like we already do for other secure code. And since we don't have any documentation, I still have no clue what the values for 0, 1 and 1 for the parameters might be. If somebody has figured it out, please do send a patch to add some comments. Debugged-by: Joonsoo Kim <iamjoonsoo.kim@lge.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

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

This will cause the wait_module_ready functionality to be effectively an expensive NOP, which will cause problems if the module hasn't really activated during its execution.

We can handle the sysc interconnect target module in a generic way for many TI SoCs. Initially let's just enable runtime PM with autosuspend, and probe the children. This can already be used for idling interconnect target modules that don't have any device driver available for the child devices. For now, the "ti,hwmods" custom binding is still required. That will be eventually deprecated in later patches. And more features will be added, such as parsing for sysc capabilities so we can continue removing the legacy platform data.

2017-10-10ARM: OMAP2+: Populate legacy resources for dma and smartreflexTony Lindgren
We can populate the legacy resources needed by dma and smartreflex from device tree in omap_device_build(). There should be no need to do this for other devices, and eventually these two remaining users will be gone too. The legacy dma will be dropped when the remaining users have been converted to use the dmaengine driver, and smartreflex can now become just a regular device driver with a few pdata callbacks. This is needed in order to remove remaining device dma, irq and io resources from the interconnect code. And while at it, let's simplify things by removing otherwise unused omap_device_build_ss() as we will never call it for more than one hwmod.

2017-10-10ARM: OMAP2+: Parse module IO range from dts for legacy "ti,hwmods" supportTony Lindgren
When removing legacy platform data for IO ranges for the hwmod interconnect code, we still need to support the "ti,hwmods" property. And as we're going to use a generic sysc device driver to handle the interconnect target instances, we can parse the information needed for legacy "ti,hwmods" IO range from the dts. It's always the first range the interconnect target module provides. Note that we want to parse the range instead of the first child device IO regs as the child device may not always be defined. The child IP device node may not exist in cases where there is no driver binding for the device, or when the child IP block may not even be functional for some SoC revisions. But the IO range of the interconnect target module is always known.
