[PATCH v3 00/14] drm/sun4i: Allwinner D1 Display Engine 2.0 Support
by Samuel Holland 26 Apr '22

26 Apr '22

This series adds binding and driver support for Display Engine 2.0 variant found in the Allwinner D1. So far it has only been tested with HDMI. I will be sending the HDMI support series separately, because the hardware comes with a brand new custom HDMI PHY, which requires some refactoring to support cleanly. This series was tested on A33, D1 and H3. Changes in v3: - Drop redundant minItems and maxItems Changes in v2: - New patch: I/O helper portability - Use Jernej's patches for mixer … [View More]

[PATCH v2 0/3] fbdev: Decouple deferred I/O from struct page
by Thomas Zimmermann 26 Apr '22

26 Apr '22

Rework the fbdev deferred-I/O to not interfere with fields of struct page. All references from deferred-I/O code to fields in struct page are gone. The rsp state is help in a separate pageref structure. Version 1 of this patchset was part of a larger attempt to improve GEM SHMEM support. [1] The patches can already be merged to resolve a long-standing issue in the fbdev code.

[RFC 00/21] Renesas r8a7795/Salvator-X HDMI output prototype
by Ulrich Hecht 26 Apr '22

26 Apr '22

Hi! This is a prototype of HDMI output support for the Renesas r8a7795 SoC and Salvator-X board. It is based on the renesas-devel-20160516-v4.6 tree and includes the bridge API conversion patches to the adv7511 and rcar-du drivers written by Archit Taneja. The obvious issue with this series is the awkward binding of the dw-hdmi bridge IP, which can be seen in the "drm: rcar-du: Add dw_hdmi driver startup" patch. Any comments on how to implement this interface properly are much appreciated. … [View More]Functionally, this series works as expected on both connectors, but EDID reading is currently broken.

[PATCH v11 0/2] drm: LogiCVC display controller support
by Paul Kocialkowski 26 Apr '22

26 Apr '22

This series introduces support for the LogiCVC display controller. The controller is a bit unusual since it is usually loaded as programmable logic on Xilinx FPGAs or Zynq-7000 SoCs. More details are presented on the main commit for the driver. More information about the controller is available on the dedicated web page: https://www.logicbricks.com/Products/logiCVC-ML.aspx Note that this driver has rather simple connector management, which was not converted to drm_panel_bridge to keep the … [View More]ability to enable the panel at first vblank but also to support DVI. Changes since v10: - Removed common compatibles for major logicvc versions; - Switched caps detection to use the version registers instead of the compatible; - Added support for major version 5 of the unit; - Used FIELD_GET from bitfield.h and removed local equivalents; - Updated copyright year; Changes since v9: - Added common compatibles for major logicvc versions; - Add support for logicvc-5; - Rebased on latest drm-misc next. Changes since v8: - Rebased on top of the latest drm-misc-next; - Dropped useless phandle-based syscon regmap support; - Switched to a single-port graph description; - Updated the device-tree schema to the port schema and added a description for the port. Change since v7: - Replaced DRM_INFO/DRM_ERROR/DRM_DEBUG_DRIVER with fashions using drm_device; - Fixed yaml binding alignment issue; - Renamed logicvc-display name to the generic "display" name; - Added patternProperties match for display in the parent mfd binding; - Used drm_atomic_get_new_crtc_state when needed; - Checked mode in mode_valid instead of atomic_check; - Switched to drmm_mode_config_init; - Removed useless logicvc_connector_destroy wrapper; - Removed useless drm_dev_put calls; - Removed atomic_commit_tail that enables the panel and streamlined the logic; - Reworked Makefile cosmetics; - Fixed checkpatch issues. Changes since v6: - Updated to the latest DRM internal API changes; - Used an enum to index dt properties instead of the name string. Changes since v5: - Subclass DRM device and use devm_drm_dev_alloc for allocation; - Removed call to drm_mode_config_cleanup (done automatically with devm); - Some related code cleanups; - Bring back not-for-merge patch adding colorkey support. Changes since v4: - Updated to internal DRM API changes (rebased on drm-misc-next); - Added Kconfig dependency on OF; - Added MAINTAINERS entry; - Used drm_err and dev_err instead of DRM_ERROR where possible; - Various cosmetic changes. Changes since v3: - Rebased on latest drm-misc; - Improved event lock wrapping; - Added collect tag; - Added color-key support patch (not for merge, for reference only). Changes since v2: - Fixed and slightly improved dt schema. Changes since v1: - Switched dt bindings documentation to dt schema; - Described more possible dt parameters; - Added support for the lvds-3bit interface; - Added support for grabbing syscon regmap from parent node; - Removed layers count property and count layers child nodes instead.

linux-next: build failure after merge of the drm-intel tree
by Stephen Rothwell 26 Apr '22

26 Apr '22

Hi all, After merging the drm-intel tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: modpost: "intel_runtime_pm_put" [drivers/gpu/drm/i915/kvmgt.ko] undefined! Possibly caused by commit 8b750bf74418 ("drm/i915/gvt: move the gvt code into kvmgt.ko") or one of tehe follow ups. I have used the drm-intel tree from next-20220422 for today. -- Cheers, Stephen Rothwell

[PATCH] drm/ssd130x: Make ssd130x_remove() return void
by Uwe Kleine-König 26 Apr '22

26 Apr '22

This function returns zero unconditionally, so there isn't any benefit of returning a value. Make it return void to be able to see at a glance that the return value of ssd130x_i2c_remove() is always zero. This patch is a preparation for making i2c remove callbacks return void.
