2021-06-08drm/bridge: ti-sn65dsi83: Add TI SN65DSI83 and SN65DSI84 driverMarek Vasut
Add driver for TI SN65DSI83 Single-link DSI to Single-link LVDS bridge and TI SN65DSI84 Single-link DSI to Dual-link or 2x Single-link LVDS bridge. TI SN65DSI85 is unsupported due to lack of hardware to test on, but easy to add. The driver operates the chip via I2C bus. Currently the LVDS clock are always derived from DSI clock lane, which is the usual mode of operation. Support for clock from external oscillator is not implemented, but it is easy to add if ever needed. Only RGB888 pixel format is implemented, the LVDS666 is not supported, but could be added if needed.

2021-05-18drm/bridge: Add ChromeOS EC ANX7688 bridge driver supportEnric Balletbo i Serra
This driver adds support for the ChromeOS EC ANX7688 HDMI to DP converter For our use case, the only reason the Linux kernel driver is necessary is to reject resolutions that require more bandwidth than what is available on the DP side. DP bandwidth and lane count are reported by the bridge via 2 registers and, as far as we know, only chips that have a firmware version greater than 0.85 support these two registers.

2020-05-05drm/bridge: chrontel-ch7033: Add a new driverLubomir Rintel
This is a driver for video encoder with VGA and DVI/HDMI outputs. There is no documentation for the chip -- the operation was guessed from what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names come from the ch7035 driver in Mediatek's GPL code dump. Only bare minimum is implemented -- no fancy stuff, such as scaling. That would only worsen our misery. We don't load the firmware and we don't need to even bother enabling the MCU. There are probably no distributable firmware images anyway. Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60, with VGA as well as DVI.

2020-02-26drm/bridge: Add bridge driver for display connectorsLaurent Pinchart
Display connectors are modelled in DT as a device node, but have so far been handled manually in several bridge drivers. This resulted in duplicate code in several bridge drivers, with slightly different (and thus confusing) logics. In order to fix this, implement a bridge driver for display connectors. The driver centralises logic for the DVI, HDMI, VGAn composite and S-video connectors and exposes corresponding bridge operations. This driver in itself doesn't solve the issue completely, changes in bridge and display controller drivers are needed to make use of the new connector driver.

Changes in v2: - Separate out edp panel specific HW resource handling from bridge driver and create a separate edp panel drivers to handle panel specific mode information and HW resources (Sean Paul). - Replace pr_* APIs to DRM_* APIs to log error or debug information (Sean Paul). - Remove some of the unnecessary structure/variable from driver (Sean Paul). - Rename the function and structure prefix "sn65dsi86" to "ti_sn_bridge" (Sean Paul / Rob Herring). - Remove most of the hard-coding and modified the bridge init sequence based on current mode (Sean Paul). - Remove the existing function to retrieve the EDID data and implemented this as an i2c_adapter and use drm_get_edid() (Sean Paul). - Remove the dummy irq handler implementation, will add back the proper irq handling later (Sean Paul). - Capture the required enable gpios in a single array based on dt entry instead of having individual descriptor for each gpio (Sean Paul). Changes in v3: - Remove usage of irq_gpio and replace it as "interrupts" property (Rob Herring). - Remove the unnecessary header file inclusions (Sean Paul). - Rearrange the header files in alphabetical order (Sean Paul). - Use regmap interface to perform i2c transactions. - Update Copyright/License field and address other review comments (Jordan Crouse). Changes in v4: - Update License/Copyright (Sean Paul). - Add Kconfig and Makefile changes (Sean Paul). - Drop i2c gpio handling from this bridge driver, since i2c sda/scl gpios will be handled by i2c master. - Update required supplies names. - Remove unnecessary goto statements (Sean Paul). - Add mutex lock to power_ctrl API to avoid race conditions (Sean Paul). - Add support to parse reference clk frequency from dt(optional). - Update the bridge chip enable/disable sequence. Changes in v5: - Fixed Kbuild test service reported warnings. Changes in v6: - Use PM runtime based ref-counting instead of local ref_count mechanism (Stephen Boyd). - Clean up some debug logs and indentations (Sean Paul). - Simplify dp rate calculation (Sean Paul). - Add support to configure refclk based on input REFCLK pin or DACP/N pin (Stephen Boyd).

Changes in v8: - Move dsi register/attach function to bridge driver probe (Andrzej Hajda). - Introduce a new helper function to write 16bit words into consecutive registers (Andrzej Hajda). - Remove unnecessary macros (Andrzej Hajda). Changes in v9: - Remove dsi register/attach from bridge probe, since dsi dev register completion also waits for any panel or bridge to get added. This creates deadlock situation when bridge driver calls dsi dev register and attach before bridge add, in its probe function. - Fix issues faced during testing of bridge driver on actual HW. - Remove unnecessary initializations (Stephen Boyd). - Use local refclk lut size instead of global macro (Sean Paul).

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.

2017-03-05drm/bridge: Drivers for megachips-stdpxxxx-ge-b850v3-fw (LVDS-DP++)Peter Senna Tschudin
The video processing pipeline on the second output on the GE B850v3: Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output Each bridge has a dedicated flash containing firmware for supporting the custom design. The result is that in this design neither the STDP4028 nor the STDP2690 behave as the stock bridges would. The compatible strings include the suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with the firmware which is specific for the GE B850v3. The driver is powerless to control the video processing pipeline, as the two bridges behaves as a single one. The driver is only needed for telling the host about EDID / HPD, and for giving the host powers to ack interrupts. This driver adds one i2c_device for each bridge, but only one drm_bridge. This design allows the creation of a functional connector that is capable of reading EDID from the STDP2690 while handling interrupts on the STDP4028.

Add very basic ti-tfp410 DVI transmitter driver. The only feature separating this from a completely dummy bridge is the EDID read support trough DDC I2C. Even that functionality should be in a separate generic connector driver. However, because of missing DRM infrastructure support the connector is implemented within the bridge driver. Some tfp410 HW specific features may be added later if needed, because there is a set of registers behind i2c if it is connected. This implementation is tested against my new tilcdc bridge support and it works with BeagleBone DVI-D Cape Rev A3. A DT binding document is also updated.
