2019-10-11drm/omap: fix max fclk divider for omap36xxTomi Valkeinen1-1/+1
commit e2c4ed148cf3ec8669a1d90dc66966028e5fad70 upstream. The OMAP36xx and AM/DM37x TRMs say that the maximum divider for DSS fclk (in CM_CLKSEL_DSS) is 32. Experimentation shows that this is not correct, and using divider of 32 breaks DSS with a flood or underflows and sync losts. Dividers up to 31 seem to work fine. There is another patch to the DT files to limit the divider correctly, but as the DSS driver also needs to know the maximum divider to be able to iteratively find good rates, we also need to do the fix in the DSS driver.

2018-05-30drm: omapdrm: dss: Move initialization code from component bind to probeLaurent Pinchart1-89/+104
[ Upstream commit 215003b4ae1d47035092fef73b6a22aa82037091 ] There's no reason to delay initialization of most of the driver (such as mapping memory I/O, getting clocks or enabling runtime PM) to the component master bind handler. This additionally fixes a real PM issue caused enabling runtime PM in the bind handler. The bind handler performs the following sequence of PM operations: pm_runtime_enable(dev); pm_runtime_get_sync(dev); ... (access the hardware to read the device revision) ... pm_runtime_put_sync(dev); If a failure occurs at this point, the error path calls pm_runtime_disable() to balance the pm_runtime_enable() call. To understand the problem, it should be noted that the bind handler is called when one of the component registers itself, which happens in the component's probe handler. Furthermore, as the components are children of the DSS, the device core calls pm_runtime_get_sync() on the DSS platform device before calling the component's probe handler. This increases the DSS power usage count but doesn't runtime resume the device, as runtime PM is disabled at that point. The bind handler is thus called with runtime PM disabled, with the device runtime suspended, but with the power usage count larger than 0. The pm_runtime_get_sync() call will thus further increase the power usage count and runtime resume the device. The pm_runtime_put_sync() handler will decrease the power usage count to a non-zero value and will thus not suspend the device. Finally, the pm_runtime_disable() call will disable runtime PM, preventing the pm_runtime_put() call in the device core from runtime suspending the device. The DSS device is thus left powered on. To fix this, move the initialization code from the bind handler to the probe handler.

commit 23970e150a0a49f9a966c46e5d22fed06226098f upstream. I believe the intention of the commit 2c9fc9bf45f8 ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver") was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions, like omap4460. By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a same way as it would treat omap4430 ES1.x This breaks HDMI audio on OMAP4460 devices (PandaES for example). Correct the match rule so we are not going to get false positive match.

commit bf25dac38f71d392a31ec074f55cbc941f1eaf1d upstream. Commit d178e034d565 ("drm: omapdrm: Move FEAT_DPI_USES_VDDS_DSI feature to dpi code") replaced usage of platform data version with SoC matching to configure DPI VDDS. The SoC match entries were incorrect, they should have matched on the machine name instead of the SoC family. Fix it.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2-0/+2
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.

2017-08-23drm/omap: fix i886 work-aroundTomi Valkeinen3-9/+25
7d267f068a8b4944d52e8b0ae4c8fcc1c1c5c5ba ("drm/omap: work-around for errata i886") changed how the PLL dividers and multipliers are calculated. While the new way should work fine for all the PLLs, it breaks omap5 PLLs. The issues seen are rather odd: seemed that the output clock rate is half of what we asked. It is unclear what's causing there issues. As a work-around this patch adds a "errata_i886" flag, which is set only for DRA7's PLLs, and the PLL setup is done according to that flag.

2017-08-15drm: omapdrm: dss: Use supported outputs instead of display typesLaurent Pinchart3-87/+17
The dss driver uses the supported display types to check whether the DSS has SDI, VENC or HDMI outputs. We can instead use the supported outputs the provide the same information. This removes the last use of the supported display types, that we can then remove as well.

2017-08-15drm: omapdrm: dss: Select features based on compatible stringLaurent Pinchart1-68/+29
Use the compatible string instead of the OMAP SoC revision to determine device features. The various OMAP3-based SoCs can't be told apart using the compatible string, use soc_device_match() to tell them apart.

2017-08-15drm: omapdrm: dpi: Replace OMAP SoC model checks with DSS modelLaurent Pinchart3-37/+45
The DPI code only needs to differentiate between major OMAP revisions, which can be obtained from the DSS compatible string. Replace the OMAP SoC model checks to prepare for removal of the OMAP SoC version platform data.

Use the compatible string instead of the OMAP SoC revision to determine device features. On OMAP34xx the features depend on the ES revision that can not be determined from the compatible string. Use soc_device_match() in that case.

2017-08-15drm: omapdrm: Don't forward set_min_bus_tput() to no-op platform codeLaurent Pinchart2-11/+6
The OMAP implementation of the set_min_bus_tput() API is a no-op. There's no point in forwarding the driver calls to the platform code. Remove the use of the related platform data callback, but keep the internal function as a reminder that the feature will need to be implemented when the OMAP platform will provide support.

2017-08-15drm: omapdrm: dsi: Store DSI model and PLL hardware data in OF dataLaurent Pinchart1-61/+55
The DSI PLL hardware data and DSS channels are selected based on the OMAP SoC model. There's no need for fine-grained model information, as the driver only needs to differentiate between OMAP3, OMAP4 and OMAP5. As this can be done through the DSI compatible string, store the corresponding information in OF match data instead to avoid accessing the OMAP SoC model.

PHY features are stored in a global variable, while they should be properties of the PHY object. As existing OMAP platforms have a single HDMI PHY this doesn't cause any issue, but doesn't follow the driver model. Move the PHY features to the HDMI PHY data structure to follow the driver model and pave the road for multiple HDMI PHYs support.
