826fc86b - drm: pl111: Move VExpress setup into versatile init

Sun, 05 Apr 2020 17:14:52 +0000

drm: pl111: Move VExpress setup into versatile initSince the VExpress setup in pl111_vexpress.c is now just a singlefunction call, let's move it into pl111_versatile.c and we can furthersimplify pl111_versatile_init() by moving the other pieces for VExpressinto pl111_vexpress_clcd_init().Cc: Eric Anholt Cc: dri-devel@lists.freedesktop.orgAcked-by: Sam Ravnborg Reviewed-by: Linus Walleij Signed-off-by: Rob Herring Link: https://patchwork.freedesktop.org/patch/msgid/20200409013947.12667-4-robh@kernel.org List of files: /linux-6.15/drivers/gpu/drm/pl111/Makefile

e08015e7 - drm/pl111: Support Nomadik LCDC variant

Thu, 21 Jun 2018 18:44:50 +0000

drm/pl111: Support Nomadik LCDC variantThe Nomadik has a variant of the PL110 known as "Color LCDController" LCDC. This variant has the same bit ordering asthe DRM subsystem (in difference from the other variants)and adds a few bits for the control of 5551, 565 etc in thecontrol register. Notably it also adds a packed RGB88824BPP mode.We add support by detecting this variant and also adding asmall plug-in that will mux the LCDC out if the ASIC happensto be muxed to the other graphics controller (they aremutually exclusive).Reviewed-by: Eric Anholt Signed-off-by: Linus Walleij Link: https://patchwork.freedesktop.org/patch/msgid/20180621184450.25377-1-linus.walleij@linaro.org List of files: /linux-6.15/drivers/gpu/drm/pl111/Makefile

ca454bd4 - drm/pl111: Support the Versatile Express

Wed, 02 May 2018 13:47:18 +0000

drm/pl111: Support the Versatile ExpressThe Versatile Express uses a special configuration controllerdeeply embedded in the system motherboard FPGA to multiplex thetwo to three (!) display controller instances out to the singleSiI9022 bridge.Set up an extra file with the logic to probe to the FPGA muxregister on the system controller bus, then parse the devicetree to see if there is a CLCD or HDLCD instance on the coretile (also known as the daughterboard) by looking in theroot of the device tree for compatible nodes.- If there is a HDLCD on the core tile, and there is a driver for it, we exit probe and deactivate the motherboard CLCD. We do not touch the DVI mux in this case, to make sure we don't break HDLCD.- If there is a CLCD on both the motherboard and the core tile (only the CA9 has this) the core tile CLCD takes precedence and get muxed to the DVI connector.- Only if there is no working graphics on the core tile, the motherboard CLCD is probed and muxed to the DVI connector.Core tile graphics should always take precedence as it canaddress all memory and is also faster, however the motherboardCLCD is good to have around for diagnostics and testing.It is possible to test the motherboard CLCD by setting thestatus = "disabled" property on the core tile CLCD orHDLCD.Scale down the Versatile Express to 16BPP so we can support a1024x768 display despite the bus bandwidth restrictions on thisplatform. (The motherboard CLCD supports slightly lowerresolution.)Cc: Liviu Dudau Cc: Pawel Moll Acked-by: Eric Anholt Tested-by: Robin Murphy Signed-off-by: Linus Walleij Link: https://patchwork.freedesktop.org/patch/msgid/20180502134719.8388-1-linus.walleij@linaro.org List of files: /linux-6.15/drivers/gpu/drm/pl111/Makefile

b2441318 - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 14:07:57 +0000

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense 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 bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe 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 caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase 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 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately 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 licenseidentifiers 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 thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion 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 correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/gpu/drm/pl111/Makefile

bed41005 - drm/pl111: Initial drm/kms driver for pl111

Thu, 13 Apr 2017 03:17:46 +0000

drm/pl111: Initial drm/kms driver for pl111This is a modesetting driver for the pl111 CLCD display controllerfound on various ARM platforms such as the Versatile Express. Thedriver has only been tested on the bcm911360_entphn platform so far,with PRIME-based buffer sharing between vc4 and clcd.It reuses the existing devicetree binding, while not using quite asmany of its properties as the fbdev driver does (those are left forfuture work).v2: Nearly complete rewrite by anholt, cutting 2/3 of the code thanks to DRM core's excellent new helpers.v3: Don't match pl110 any more, don't attach if we don't have a DRM panel, use DRM_GEM_CMA_FOPS, update MAINTAINERS, use the simple display helper, use drm_gem_cma_dumb_create (same as our wrapper).v4: Change the driver's .name to not clash with fbdev in sysfs, drop platform alias, drop redundant "drm" in DRM driver name, hook up .prepare_fb to the CMA helper so that DMA fences should work.v5: Move register definitions inside the driver directory, fix build in COMPILE_TEST and !AMBA mode.v6: Drop TIM2_CLKSEL for now to be consistent with existing DT bindings, switch back to external register definitions.Signed-off-by: Tom Cooksey Signed-off-by: Eric Anholt Reviewed-by: Linus Walleij (v5)Acked-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170413031746.12921-2-eric@anholt.net List of files: /linux-6.15/drivers/gpu/drm/pl111/Makefile
