* drm/bridge-connector: move to DRM_DISPLAY_HELPER moduleDmitry Baryshkov2024-09-031-0/+2
| | | | | | | | | | | | drm_bridge_connector is a "leaf" driver, belonging to the display helper, rather than the "CRTC" drm_kms_helper module. Move the driver to the drm/display and add necessary Kconfig selection clauses.

| | | | | | | | | | | | | | | With the recent switch from fbdev-generic to fbdev-dma, the driver now requires the DRM GEM DMA helpers.

* drm: Switch DRM_DISPLAY_DP_HELPER to depends onMaxime Ripard2024-03-281-1/+1
| | | | | | | | | | | | | | | Most of our helpers have relied on being selected so far through Kconfig, but that creates issues when we have multiple layers of helpers with some depending on others. Indeed, select doesn't select a dependency's dependencies, and thus isn't super intuitive. Depends on however doesn't have that limitation, so we can just switch all the drivers that were selecting DRM_DISPLAY_DP_HELPER to depend on it.

* drm/display: Make DisplayPort AUX bus Kconfig name consistentMaxime Ripard2024-03-281-1/+1
| | | | | | | | | | | | | While most display helpers Kconfig symbols have the DRM_DISPLAY prefix, the DisplayPort AUX bus implementation uses DRM_DP_AUX_BUS.

* drm/mediatek: dp: Add support for embedded DisplayPort aux-busAngeloGioacchino Del Regno2023-08-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | For the eDP case we can support using aux-bus on MediaTek DP: this gives us the possibility to declare our panel as generic "panel-edp" which will automatically configure the timings and available modes via the EDID that we read from it. To do this, move the panel parsing at the end of the probe function so that the hardware is initialized beforehand and also initialize the DPTX AUX block and power both on as, when we populate the aux-bus, the panel driver will trigger an EDID read to perform panel detection. Last but not least, since now the AUX transfers can happen in the separated aux-bus, it was necessary to add an exclusion for the cable_plugged_in check in `mtk_dp_aux_transfer()` and the easiest way to do this is to simply ignore checking that when the bridge type is eDP.

* drm/mediatek: Add MT8195 Embedded DisplayPort driverMarkus Schneider-Pargmann2022-09-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a embedded displayport driver for the MediaTek mt8195 SoC. It supports the MT8195, the embedded DisplayPort units. It offers DisplayPort 1.4 with up to 4 lanes. The driver creates a child device for the phy. The child device will never exist without the parent being active. As they are sharing a register range, the parent passes a regmap pointer to the child so that both can work with the same register range. The phy driver sets device data that is read by the parent to get the phy device that can be used to control the phy properties.

* drm/gem: rename GEM CMA helpers to GEM DMA helpersDanilo Krummrich2022-08-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename "GEM CMA" helpers to "GEM DMA" helpers - considering the hierarchy of APIs (mm/cma -> dma -> gem dma) calling them "GEM DMA" 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 be confused 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 the following modifications in some DRM Kconfig files - select CMA if HAVE_DMA_CONTIGUOUS + select DMA if HAVE_DMA_CONTIGUOUS as well as manually picking the occurrences of 'CMA'/'cma' in comments and documentation which relate to "GEM CMA", but not "FB CMA". Also drivers/gpu/drm/Makefile was fixed up manually after renaming drm_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`.
