| | * memory: ti-emif-sram: introduce relocatable suspend/resume handlersDave Gerlach2017-12-037-0/+791
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain SoCs like Texas Instruments AM335x and AM437x require parts of the EMIF PM code to run late in the suspend sequence from SRAM, such as saving and restoring the EMIF context and placing the memory into self-refresh. One requirement for these SoCs to suspend and enter its lowest power mode, called DeepSleep0, is that the PER power domain must be shut off. Because the EMIF (DDR Controller) resides within this power domain, it will lose context during a suspend operation, so we must save it so we can restore once we resume. However, we cannot execute this code from external memory, as it is not available at this point, so the code must be executed late in the suspend path from SRAM. This patch introduces a ti-emif-sram driver that includes several functions written in ARM ASM that are relocatable so the PM SRAM code can use them. It also allocates a region of writable SRAM to be used by the code running in the executable region of SRAM to save and restore the EMIF context. It can export a table containing the absolute addresses of the available PM functions so that other SRAM code can branch to them. This code is required for suspend/resume on AM335x and AM437x to work. In addition to this, to be able to share data structures between C and the ti-emif-sram-pm assembly code, we can automatically generate all of the C struct member offsets and sizes as macros by processing emif-asm-offsets.c into assembly code and then extracting the relevant data as is done for the generated platform asm-offsets.h files.

* / License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-022-0/+2

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.

All drivers implement this feature now so that IOMMU core code can rely on it. - finish support for 'struct iommu_device' in iommu drivers.

Thus, currently subsys_initcall for SMI is unnecessary, SMI will be always probe defered by power-domain. Degrade it to module_init. In addition, there are two small changes about the probe sequence: 1) Delete this two lines. if (!dev->pm_domain) return -EPROBE_DEFER; This is not helpful. the platform driver framework guarantee this. The "dev_pm_domain_attach" in the "platform_drv_probe" will return EPROBE_DEFER if its powerdomain is not ready. 2) Add the probe-defer for the smi-larb device should waiting for smi-common. In mt2712, there are 2 smi-commons, 10 smi-larbs. All will be probe-defered by the power-domain, there is seldom case that smi-larb probe done before smi-common. then it will hang like this: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = ffffff800a4e0000 [00000000] *pgd=00000000beffe003[ 17.610026] , *pud=00000000beffe003 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported in [1] and in [2] it's not possible to set the device tree property 'atmel,smc-tdf-ns' to zero, although the SoC allows a setting of 0ns for the t_DF time. Allow this setting by doing the same thing as in the atmel nand controller driver by setting ncycles to ATMEL_SMC_MODE_TDF_MIN if zero is set in the dts.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting optional EBI/SMC properties through device tree always fails due to wrong evaluation of the return value of atmel_ebi_xslate_smc_timings(). If you put some of those properties in your dts file, but not 'atmel,smc-tdf-ns' the local variable 'required' in atmel_ebi_xslate_smc_timings() stays on 'false' after the first 'if' block. This leads to setting 'ret' to -EINVAL in the first run of the following 'for' loop which is then the return value of this function. However if you set 'atmel,smc-tdf-ns' in the dts file and everything in atmel_ebi_xslate_smc_timings() works well, it returns the content of 'required' which is 'true' then. So the function atmel_ebi_xslate_smc_timings() always returns non-zero which lets its call in atmel_ebi_xslate_smc_config() always fail and thus returning -EINVAL, so the EBI configuration for this node fails. Judging from the following code evaluating the local 'required' variable in atmel_ebi_xslate_smc_config() and the call of caps->xlate_config in atmel_ebi_dev_setup() it's probably right to only let the call fail if a negative error code is returned.
