[ Upstream commit 5f3417569165a8ee57654217f73e0160312f409c ] The bridge loses its hw state when the cable is unplugged. If we detect this case in the hpd handler, reset its state.

2018-08-24drm/bridge/sii8620: Fix display of packed pixel modesMaciej Purski1-1/+16
[ Upstream commit fdddc65ab35d575b42aab411b2dc687601eab680 ] Current implementation does not guarantee packed pixel modes working with every dongle. There are some dongles, which require selecting the output mode explicitly. Write proper values to registers in packed_pixel mode, based on how it is done in vendor's code. Select output color space: RGB (no packed pixel) or YCBCR422 (packed pixel).

[ Upstream commit e8b92efa629dac0e70ea4145c5e70616de5f89c8 ] Currently packed pixel modes in MHL2 can't be displayed. The device automatically recognizes output format, so setting format other than RGB causes failure. Fix it by writing proper values to registers.

[ Upstream commit 9378cecb1ce5d618b8aff4d65113ddcf72fc1011 ] Buffer overflow error should not occur, as mode_fixup() callback filters pixel clock value and it should never exceed 600000.

2018-05-30drm/bridge: sii902x: Retry status read after DDI I2CLinus Walleij1-4/+16
[ Upstream commit 2e7a66a8b5ebf1b04a866e5d7c981640f7f62934 ] The following happens when connection a DVI output driven from the SiI9022 using a DVI-to-VGA adapter plug: i2c i2c-0: sendbytes: NAK bailout. i2c i2c-0: sendbytes: NAK bailout. Then no picture. Apparently the I2C engine inside the SiI9022 is not smart enough to try to fall back to DDC I2C. Or the vendor have not integrated the electronics properly. I don't know which one it is. After this, the I2C bus seems stalled and the first attempt to read the status register fails, and the code returns with negative return value, and the display fails to initialized. Instead, retry status readout five times and continue even if this fails. Tested on the ARM Versatile Express with a DVI-to-VGA connector, it now gives picture. Introduce a helper struct device *dev variable to make the code more readable.

2017-12-14drm/bridge: analogix dp: Fix runtime PM state in get_modes() callbackMarek Szyprowski1-0/+2
commit 510353a63796d467b41237ab4f136136f68c297d upstream. get_modes() callback might be called asynchronously from the DRM core and it is not synchronized with bridge_enable(), which sets proper runtime PM state of the main DP device. Fix this by calling pm_runtime_get_sync() before calling drm_get_edid(), which in turn calls drm_dp_i2c_xfer() and analogix_dp_transfer() to ensure that main DP device is runtime active when doing any access to its registers. This fixes the following kernel issue on Samsung Exynos5250 Snow board: Unhandled fault: imprecise external abort (0x406) at 0x00000000 pgd = c0004000 [00000000] *pgd=00000000 Internal error: : 406 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 PID: 62 Comm: kworker/0:2 Not tainted 4.13.0-rc2-00364-g4a97a3da420b #3357 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) Workqueue: events output_poll_execute task: edc14800 task.stack: edcb2000 PC is at analogix_dp_transfer+0x15c/0x2fc LR is at analogix_dp_transfer+0x134/0x2fc pc : [<c0468538>] lr : [<c0468510>] psr: 60000013 sp : edcb3be8 ip : 0000002a fp : 00000001 r10: 00000000 r9 : edcb3cd8 r8 : edcb3c40 r7 : 00000000 r6 : edd3b380 r5 : edd3b010 r4 : 00000064 r3 : 00000000 r2 : f0ad3000 r1 : edcb3c40 r0 : edd3b010 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 4000406a DAC: 00000051 Process kworker/0:2 (pid: 62, stack limit = 0xedcb2210) Stack: (0xedcb3be8 to 0xedcb4000) [<c0468538>] (analogix_dp_transfer) from [<c0424ba4>] (drm_dp_i2c_do_msg+0x8c/0x2b4) [<c0424ba4>] (drm_dp_i2c_do_msg) from [<c0424e64>] (drm_dp_i2c_xfer+0x98/0x214) [<c0424e64>] (drm_dp_i2c_xfer) from [<c057b2d8>] (__i2c_transfer+0x140/0x29c) [<c057b2d8>] (__i2c_transfer) from [<c057b4a4>] (i2c_transfer+0x70/0xe4) [<c057b4a4>] (i2c_transfer) from [<c0441de4>] (drm_do_probe_ddc_edid+0xb4/0x114) [<c0441de4>] (drm_do_probe_ddc_edid) from [<c0441e5c>] (drm_probe_ddc+0x18/0x28) [<c0441e5c>] (drm_probe_ddc) from [<c0445728>] (drm_get_edid+0x124/0x2d4) [<c0445728>] (drm_get_edid) from [<c0465ea0>] (analogix_dp_get_modes+0x90/0x114) [<c0465ea0>] (analogix_dp_get_modes) from [<c0425e8c>] (drm_helper_probe_single_connector_modes+0x198/0x68c) [<c0425e8c>] (drm_helper_probe_single_connector_modes) from [<c04325d4>] (drm_setup_crtcs+0x1b4/0xd18) [<c04325d4>] (drm_setup_crtcs) from [<c04344a8>] (drm_fb_helper_hotplug_event+0x94/0xd0) [<c04344a8>] (drm_fb_helper_hotplug_event) from [<c0425a50>] (drm_kms_helper_hotplug_event+0x24/0x28) [<c0425a50>] (drm_kms_helper_hotplug_event) from [<c04263ec>] (output_poll_execute+0x6c/0x174) [<c04263ec>] (output_poll_execute) from [<c0136f18>] (process_one_work+0x188/0x3fc) [<c0136f18>] (process_one_work) from [<c01371f4>] (worker_thread+0x30/0x4b8) [<c01371f4>] (worker_thread) from [<c013daf8>] (kthread+0x128/0x164) [<c013daf8>] (kthread) from [<c0108510>] (ret_from_fork+0x14/0x24) Code: 0a000002 ea000009 e2544001 0a00004a (e59537c8) ---[ end trace cddc7919c79f7878 ]--- Reported-by: Misha Komarovskiy <zombah@gmail.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Archit Taneja <architt@codeaurora.org> Link: https://patchwork.freedesktop.org/patch/msgid/20171121074936.22520-1-m.szyprowski@samsung.com
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.

It adds one export to the radix tree code for new i915 use case. There are some minor AGP cleanups (don't see that too often). Changes to the vbox driver in staging to avoid breaking compilation.

HDMI 2.0 PHY Currently HDMI 2.0 PHYs do not have a default configuration function. As *some* of the HDMI 2.0 PHYs have the same register layout as the 3D PHYs we can provide the same default configuration function for both and still let user overwrite this with custom configuration function if needed. If, for some reason, the PHY is custom or has a register different register layout then custom configuration function *must* be provided in order for the system to work correctly. As we prefer the pdata provided configuration function over the internal one this change will not make any impact in custom platforms.

2017-07-14drm: handle HDMI 2.0 VICs in AVI info-framesShashank Sharma3-3/+4
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64). For any other mode, the VIC filed in AVI infoframes should be 0. HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is extended to (VIC 1-107). This patch adds a bool input variable, which indicates if the connected sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a HDMI 2.0 VIC to a HDMI 1.4 sink. This patch touches all drm drivers, who are callers of this function drm_hdmi_avi_infoframe_from_display_mode but to make sure there is no change in current behavior, is_hdmi2 is kept as false. In case of I915 driver, this patch: - checks if the connected display is HDMI 2.0. - HDMI infoframes carry one of this two type of information: - VIC for 4K modes for HDMI 1.4 sinks - S3D information for S3D modes As CEA-861-F has already defined VICs for 4K videomodes, this patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks, until the mode is 3D.
