aca1cbc1 - drm/stm: lvds: add new STM32 LVDS Display Interface Transmitter driver

Mon, 26 Feb 2024 10:48:06 +0000

drm/stm: lvds: add new STM32 LVDS Display Interface Transmitter driverThe Low-Voltage Differential Signaling (LVDS) Display InterfaceTransmitter handles the LVDS protocol: it maps the pixels received fromthe upstream Pixel-DMA LCD-TFT Display Controller (LTDC) onto the LVDSPHY.It is composed of three sub blocks: * LVDS host: handles the LVDS protocol (FPD / OpenLDI) and maps its input pixels onto the data lanes of the PHY * LVDS PHY: parallelize the data and drives the LVDS data lanes * LVDS wrapper: handles top-level settingsThe LVDS controller driver supports the following high-level features: * FDP-Link-I and OpenLDI (v0.95) protocols * Single-Link or Dual-Link operation * Single-Display or Double-Display (with the same content duplicated on both) * Flexible Bit-Mapping, including JEIDA and VESA * RGB888 or RGB666 output * Synchronous design, with one input pixel per clock cycleSigned-off-by: Raphael Gallais-Pou Acked-by: Yannick Fertre Signed-off-by: Philippe Cornu Link: https://patchwork.freedesktop.org/patch/msgid/20240226-lvds-v6-2-15e3463fbe70@foss.st.com List of files: /linux-6.15/drivers/gpu/drm/stm/Kconfig

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

Tue, 02 Aug 2022 00:04:03 +0000

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/stm/Kconfig
