drm: xlnx: zynqmp_dpsub: Add DP audio supportAdd basic DisplayPort audio support.Support non-live audio playback from two PCMs (DMA channels), and thevolume control in the audio mixer.As older dtb files may not have the audio DMA channels defined, thedriver will just mark the audio support as disabled if the audio DMA ismissing, and will continue with only display support.Note: Reset doesn't seem to work (ZYNQMP_DISP_AUD_SOFT_RESET). If we doa reset, audio playback won't start again even if, afaics, we do set upall the necessary registers. So, at the moment, resetting the audioblock in dp_dai_hw_free() is commented out.Tested-by: Anatoliy Klymenko Reviewed-by: Vishal Sagar Signed-off-by: Tomi Valkeinen Link: https://patchwork.freedesktop.org/patch/msgid/20241023-xilinx-dp-audio-v4-3-5128881457be@ideasonboard.com List of files: /linux/drivers/gpu/drm/xlnx/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/xlnx/Kconfig

Update all related Kconfig and Makefile rules.Besides the existing code for DisplayPort, the new module willcontain helpers for other video-output standards, such as HDMI.Drivers will have to select their required video-output helpers.Linking all display-related code into a single module avoids theproliferation of small kernel modules.The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz,and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespaceto drm_display_helper.v2: * mention module parameters in commit message (Javier) * distiguish between display module and DP support in Kconfig * update Makefile rules for DP helpers * move Kconfig rules into separate file under display/Signed-off-by: Thomas Zimmermann Reviewed-by: Lyude Paul Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-4-tzimmermann@suse.de List of files: /linux/drivers/gpu/drm/xlnx/Kconfig
