Tue, 07 Apr 2026 14:24:25 +0200

drm/mxsfb/lcdif: use DRM_BRIDGE_ATTACH_NO_CONNECTOR and the bridge-connectorConvert this driver to DRM_BRIDGE_ATTACH_NO_CONNECTOR and to thedrm_bridge_connector framework which is the current DRM bridge bestpractice.Based on the in-tree dts[i] files this introduces no regression. Based onthe kernel doc of drm_bridge_connector.c: * To make use of this helper, all bridges in the chain shall report bridge * operation flags (&drm_bridge->ops) and bridge output type * (&drm_bridge->type), as well as the DRM_BRIDGE_ATTACH_NO_CONNECTOR attach * flag (none of the bridges shall create a DRM connector directly).and each of the 3 LCDIF blocks in the i.MX8MP, all of them comply with theabove requirement: * For the LCDIF3, the pipeline is: LCDIF3 -> fsl,imx8mp-hdmi-pvi -> fsl,imx8mp-hdmi-tx -> HDMI connector And the involved bridges are: * fsl,imx8mp-hdmi-pvi has ops = 0 (it doesn't set it) because it implements none the optional features mentioned by those flags, and it honors the DRM_BRIDGE_ATTACH_NO_CONNECTOR by propagating it * fsl,imx8mp-hdmi-tx is implemented based on dw-hdmi, which sets ops as appropriate and also propagates the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag * display-connector (enabled via the DT overlay if needed) sets ops and makes DRM_BRIDGE_ATTACH_NO_CONNECTOR mandatory * The LCDIF2 involves the panel-bridge, display-connector and lvds-decoder (even though only the pane-bridge is currently supported), and all these three also set ops as needed and propagate DRM_BRIDGE_ATTACH_NO_CONNECTOR or make it mandatory. * The LCDIF1 is used with the adv7511, tc358767 and the panel bridge drivers which also comply with the requirements.Tested-by: Martyn Welch Tested-by: Alexander Stein # TQMa8MPxL/MBa8MPxLReviewed-by: Liu Ying Link: https://patch.msgid.link/20260407-drm-lcdif-dbanc-v4-11-247a16e61ef9@bootlin.comSigned-off-by: Luca Ceresoli List of files: /linux/drivers/gpu/drm/mxsfb/Kconfig

Tue, 02 Aug 2022 02:04:03 +0200

drm/gem: rename GEM CMA helpers to GEM DMA helpersRename "GEM CMA" helpers to "GEM DMA" helpers - considering thehierarchy of APIs (mm/cma -> dma -> gem dma) calling them "GEMDMA" seems to be more applicable.Besides that, commit e57924d4ae80 ("drm/doc: Task to rename CMA helpers")requests to rename the CMA helpers and implies that people seem to beconfused about the naming.In order to do this renaming the following script was used:``` #!/bin/bash DIRS="drivers/gpu include/drm Documentation/gpu" REGEX_SYM_UPPER="[0-9A-Z_\-]" REGEX_SYM_LOWER="[0-9a-z_\-]" REGEX_GREP_UPPER="(${REGEX_SYM_UPPER}*)(GEM)_CMA_(${REGEX_SYM_UPPER}*)" REGEX_GREP_LOWER="(${REGEX_SYM_LOWER}*)(gem)_cma_(${REGEX_SYM_LOWER}*)" REGEX_SED_UPPER="s/${REGEX_GREP_UPPER}/\1\2_DMA_\3/g" REGEX_SED_LOWER="s/${REGEX_GREP_LOWER}/\1\2_dma_\3/g" # Find all upper case 'CMA' symbols and replace them with 'DMA'. for ff in $(grep -REHl "${REGEX_GREP_UPPER}" $DIRS) do sed -i -E "$REGEX_SED_UPPER" $ff done # Find all lower case 'cma' symbols and replace them with 'dma'. for ff in $(grep -REHl "${REGEX_GREP_LOWER}" $DIRS) do sed -i -E "$REGEX_SED_LOWER" $ff done # Replace all occurrences of 'CMA' / 'cma' in comments and # documentation files with 'DMA' / 'dma'. for ff in $(grep -RiHl " cma " $DIRS) do sed -i -E "s/ cma / dma /g" $ff sed -i -E "s/ CMA / DMA /g" $ff done # Rename all 'cma_obj's to 'dma_obj'. for ff in $(grep -RiHl "cma_obj" $DIRS) do sed -i -E "s/cma_obj/dma_obj/g" $ff done```Only a few more manual modifications were needed, e.g. reverting thefollowing modifications in some DRM Kconfig files - select CMA if HAVE_DMA_CONTIGUOUS + select DMA if HAVE_DMA_CONTIGUOUSas well as manually picking the occurrences of 'CMA'/'cma' in comments anddocumentation which relate to "GEM CMA", but not "FB CMA".Also drivers/gpu/drm/Makefile was fixed up manually after renamingdrm_gem_cma_helper.c to drm_gem_dma_helper.c.This patch is compile-time tested building a x86_64 kernel with`make allyesconfig && make drivers/gpu/drm`.Acked-by: Sam Ravnborg Acked-by: Thomas Zimmermann Reviewed-by: Laurent Pinchart Signed-off-by: Danilo Krummrich Reviewed-by: Liviu Dudau #drivers/gpu/drm/armSigned-off-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20220802000405.949236-4-dakr@redhat.com List of files: /linux/drivers/gpu/drm/mxsfb/Kconfig
