drm/mediatek: dp: Add support for embedded DisplayPort aux-busFor the eDP case we can support using aux-bus on MediaTek DP: thisgives us the possibility to declare our panel as generic "panel-edp"which will automatically configure the timings and available modesvia the EDID that we read from it.To do this, move the panel parsing at the end of the probe functionso that the hardware is initialized beforehand and also initializethe DPTX AUX block and power both on as, when we populate theaux-bus, the panel driver will trigger an EDID read to performpanel detection.Last but not least, since now the AUX transfers can happen in theseparated aux-bus, it was necessary to add an exclusion for thecable_plugged_in check in `mtk_dp_aux_transfer()` and the easiestway to do this is to simply ignore checking that when the bridgetype is eDP.Signed-off-by: AngeloGioacchino Del Regno Tested-by: Chen-Yu Tsai Reviewed-by: Alexandre Mergnat Reviewed-by: CK Hu Link: https://patchwork.kernel.org/project/dri-devel/patch/20230725073234.55892-10-angelogioacchino.delregno@collabora.com/Signed-off-by: Chun-Kuang Hu List of files: /linux-6.15/drivers/gpu/drm/mediatek/Kconfig

It offersDisplayPort 1.4 with up to 4 lanes.The driver creates a child device for the phy. The child device willnever exist without the parent being active. As they are sharing aregister range, the parent passes a regmap pointer to the child so thatboth can work with the same register range. The phy driver sets devicedata that is read by the parent to get the phy device that can be usedto control the phy properties.This driver is based on an initial version byJitao shi Signed-off-by: Markus Schneider-Pargmann Signed-off-by: Guillaume Ranquet Signed-off-by: Bo-Chen Chen Reviewed-by: CK Hu Tested-by: AngeloGioacchino Del Regno Reviewed-by: AngeloGioacchino Del Regno Signed-off-by: Dmitry Osipenko Link: https://patchwork.freedesktop.org/patch/msgid/20220901044149.16782-4-rex-bc.chen@mediatek.com List of files: /linux-6.15/drivers/gpu/drm/mediatek/Kconfig

4a83c26a - drm/gem: rename GEM CMA helpers to GEM DMA helpers

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-6.15/drivers/gpu/drm/mediatek/Kconfig
