[PATCH for v5.9] ARM: dts: mxs: Replace HTTP links with HTTPS ones
by Alexander A. Klimov 21 Jul '20

21 Jul '20

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Klimov <grandmaster(a)al2klimov.de>' v5.7..master (Actually letting a shell for loop submit all this stuff for me.)

Sorry again to all maintainers who complained about subject lines. Now I realized that you want an actually perfect prefixes, not just subsystem ones. I tried my best...

io-mapping: Indicate mapping failure
by Michael J. Ruhl 21 Jul '20

21 Jul '20

I found this when my system crashed long after the mapping failure. The expected behavior should have been driver exit. Since this is almost exclusively used for drm, I am posting to the dri mailing list. Should this go to another list as well? Thanks, Mike Cc: Mike Rapoport <rppt(a)linux.ibm.com> Cc: Andy Shevchenko <andriy.shevchenko(a)linux.intel.com>

[PATCH v7 0/5] Add support for iMX8MQ Display Controller Subsystem
by Laurentiu Palcu 21 Jul '20

21 Jul '20

From: Laurentiu Palcu <laurentiu.palcu(a)nxp.com> Hi, This patchset adds initial DCSS support for iMX8MQ chip. Initial support includes only graphics plane support (no video planes), no HDR10 capabilities, no graphics decompression (only linear, tiled and super-tiled buffers allowed). Support for the rest of the features will be added incrementally, in subsequent patches. The patchset was tested with both HDP driver (in the downstream tree) and the upstream MIPI-DSI driver (with a couple of patches on top, to make it work correctly with DCSS). Thanks, Laurentiu Changes in v7: * Added a patch to initialize the connector using the drm_bridge_connector API as Sam suggested. Tested it using NWL_DSI and ADV7535 with Guido's patch [1] applied and one fix for ADV [2]. Also, some extra patches for ADV and NWL were needed, from our downstream tree, which will be upstreamed soon by their author; * Rest of the patches are untouched; [1] https://lists.freedesktop.org/archives/dri-devel/2020-July/273025.html [2] https://lists.freedesktop.org/archives/dri-devel/2020-July/273132.html Changes in v6: * Addressed Rob's comment and added "additionalProperties: false" at the end of the bindings' properties. However, this change surfaced an issue with the assigned-clock* properties not being documented in the properties section. Added the descriptions and the bindings patch will need another review; * Added an entry for DCSS driver in the MAINTAINERS file; * Removed the component framework patch altogether; Changes in v5: * Rebased to latest; * Took out component framework support and made it a separate patch so that people can still test with HDP driver, which makes use of it. But the idea is to get rid of it once HDP driver's next versions will remove component framework as well; * Slight improvement to modesetting: avoid cutting off the pixel clock if the new mode and the old one are equal. Also, in this case, is not necessary to wait for DTG to shut off. This would allow to switch from 8b RGB to 12b YUV422, for example, with no interruptions (at least from DCSS point of view); * Do not fire off CTXLD when going to suspend, unless it still has entries that need to be committed to DCSS; * Addressed Rob's comments on bindings; Changes in v4: * Addressed Lucas and Philipp's comments: * Added DRM_KMS_CMA_HELPER dependency in Kconfig; * Removed usage of devm_ functions since I'm already doing all the clean-up in the submodules_deinit(); * Moved the drm_crtc_arm_vblank_event() in dcss_crtc_atomic_flush(); * Removed en_completion variable from dcss_crtc since this was introduced mainly to avoid vblank timeout warnings which were fixed by arming the vblank event in flush() instead of begin(); * Removed clks_on and irq_enabled flags since all the calls to enabling/disabling clocks and interrupts were balanced; * Removed the custom atomic_commit callback and used the DRM core helper and, in the process, got rid of a workqueue that wasn't necessary anymore; * Fixed some minor DT binding issues flagged by Philipp; * Some other minor changes suggested by Lucas; * Removed YUV formats from the supported formats as these cannot work without the HDR10 module CSCs and LUTs. Will add them back when I will add support for video planes; Changes in v3: * rebased to latest linux-next and made it compile as drmP.h was removed; * removed the patch adding the VIDEO2_PLL clock. It's already applied; * removed an unnecessary 50ms sleep in the dcss_dtg_sync_set(); * fixed a a spurious hang reported by Lukas Hartmann and encountered by me several times; * mask DPR and DTG interrupts by default, as they may come enabled from U-boot; Changes in v2: * Removed '0x' in node's unit-address both in DT and yaml; * Made the address region size lowercase, to be consistent; * Removed some left-over references to P010; * Added a Kconfig dependency of DRM && ARCH_MXC. This will also silence compilation issues reported by kbuild for other architectures; Laurentiu Palcu (5): drm/imx: compile imx directory by default drm/imx: Add initial support for DCSS on iMX8MQ drm/imx/dcss: use drm_bridge_connector API MAINTAINERS: Add entry for i.MX 8MQ DCSS driver dt-bindings: display: imx: add bindings for DCSS .../bindings/display/imx/nxp,imx8mq-dcss.yaml | 104 +++ MAINTAINERS | 8 + drivers/gpu/drm/Makefile | 2 +- drivers/gpu/drm/imx/Kconfig | 2 + drivers/gpu/drm/imx/Makefile | 1 + drivers/gpu/drm/imx/dcss/Kconfig | 9 + drivers/gpu/drm/imx/dcss/Makefile | 6 + drivers/gpu/drm/imx/dcss/dcss-blkctl.c | 70 ++ drivers/gpu/drm/imx/dcss/dcss-crtc.c | 219 +++++ drivers/gpu/drm/imx/dcss/dcss-ctxld.c | 424 +++++++++ drivers/gpu/drm/imx/dcss/dcss-dev.c | 325 +++++++ drivers/gpu/drm/imx/dcss/dcss-dev.h | 177 ++++ drivers/gpu/drm/imx/dcss/dcss-dpr.c | 562 ++++++++++++ drivers/gpu/drm/imx/dcss/dcss-drv.c | 138 +++ drivers/gpu/drm/imx/dcss/dcss-dtg.c | 409 +++++++++ drivers/gpu/drm/imx/dcss/dcss-kms.c | 198 +++++ drivers/gpu/drm/imx/dcss/dcss-kms.h | 44 + drivers/gpu/drm/imx/dcss/dcss-plane.c | 405 +++++++++ drivers/gpu/drm/imx/dcss/dcss-scaler.c | 826 ++++++++++++++++++ drivers/gpu/drm/imx/dcss/dcss-ss.c | 180 ++++ 20 files changed, 4108 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/display/imx/nxp,imx8mq-dcss.yaml create mode 100644 drivers/gpu/drm/imx/dcss/Kconfig create mode 100644 drivers/gpu/drm/imx/dcss/Makefile create mode 100644 drivers/gpu/drm/imx/dcss/dcss-blkctl.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-crtc.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-ctxld.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-dev.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-dev.h create mode 100644 drivers/gpu/drm/imx/dcss/dcss-dpr.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-drv.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-dtg.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-kms.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-kms.h create mode 100644 drivers/gpu/drm/imx/dcss/dcss-plane.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-scaler.c create mode 100644 drivers/gpu/drm/imx/dcss/dcss-ss.c -- 2.23.0

[PATCH 0/5] ARM: sunxi: Add support for MSI Primo73 tablet
by Chen-Yu Tsai 21 Jul '20

21 Jul '20

From: Chen-Yu Tsai <wens(a)csie.org> Hi everyone, This series add support for MSI's Primo73 tablet. This is a 7" tablet based on Allwinner's A20 SoC. The tablet uses some unknown LCD panel, with only serial number markings, and what appears to be a part number. Searching the Internet for said part number yielded no usable results. Hence this panel is described solely using the panel-dpi binding. The display timing values were retrieved from the hardware description file from the original Android system. A new property for the panel-dpi binding is added to describe the color depth of the panel, which is normally included the panel description in panel-simple. Otherwise this would be undefined in the panel-dpi case and left to encoder drivers to make up. I believe this would be separate from the bus format, which was added earlier and then retracted. Patches 1 and 2 add the new color depth property to the device tree binding and the panel-simple driver. Patch 3 adds the board compatible string to the list of boards. Patch 4 adds a pinmux option for LCD0 full 24-bit output, with control signals, for the A20. Patch 5 adds the device tree file for the Primo73. Please have a look.
