drm/display: Move SCDC helpers into display-helper library

2022-04-25T09:19:37Z

SCDC is the Status and Control Data Channel for HDMI. Move the SCDC helpers into display/ and split the header into files for core and helpers. Update all affected drivers. No functional changes. To avoid the proliferation of Kconfig options, SCDC is part of DRM's support for HDMI. If necessary, a new option could make SCDC an independent feature.

drm/display: Move DSC header and helpers into display-helper module

2022-04-25T09:19:36Z

DSC is the Display Stream Compression standard for DisplayPort. Move the DSC code into display/ and split the header into files for protocol core and DRM helpers. Adapt all users of the code. No functional changes. To avoid the proliferation of Kconfig options, DSC is part of DRM's support for DisplayPort. If necessary, a new option could make DSC an independent feature.

drm: Rename dp/ to display/

2022-04-25T09:17:45Z

Rename dp/ to display/ to account for additional display-related helpers, such as HDMI. Update all related include statements. No functional changes. Various drivers, such as i915 and amdgpu, use similar naming scheme by putting code for video-output standards into a local display/ directory. The new directory's name is aligned with this convention. v2: * update commit message (Javier) Signed-off-by: Thomas Zimmermann Reviewed-by: Lyude Paul Reviewed-by: Javier Martinez Canillas Reviewed-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-3-tzimmermann@suse.de

drm: Add driver for Solomon SSD130x OLED displays

2022-02-16T12:29:04Z

This adds a DRM driver for SSD1305, SSD1306, SSD1307 and SSD1309 Solomon OLED display controllers. It's only the core part of the driver and a bus specific driver is needed for each transport interface supported by the display controllers.

drm/dp: Move DisplayPort helpers into separate helper module

2022-01-17T10:25:44Z

Move DisplayPort functions into a separate module to reduce the size of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c This change can help to reduce the size of the kernel binary. Some numbers from a x86-64 test build: Before: drm_kms_helper.ko: 447480 bytes After: drm_dp_helper.ko: 216632 bytes drm_kms_helper.ko: 239424 bytes For early-boot graphics, generic DRM drivers, such as simpledrm, require DRM KMS helpers to be built into the kernel. Generic helper functions for DisplayPort take up a significant portion of DRM KMS helper library. These functions are not used by generic drivers and can be loaded as a module. v3: * fix include statement in DRM selftests v2: * move DP helper code into dp/ (Jani) Signed-off-by: Thomas Zimmermann Acked-by: Lyude Paul Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20220114114535.29157-4-tzimmermann@suse.de

drm/sprd: add Unisoc's drm kms master

Adds drm support for the Unisoc's display subsystem. This is drm kms driver, this driver provides support for the application framework in Android, Yocto and more. Application framework can access Unisoc's display internal peripherals through libdrm or libkms, it's test ok by modetest (DRM/KMS test tool) and Android HWComposer. v4: - Move the devm_drm_dev_alloc to master_ops->bind function. - The managed drmm_mode_config_init() it is no longer necessary for drivers to explicitly call drm_mode_config_cleanup, so delete it. v5: - Remove subdir-ccflgas-y for Makefile. - Keep the selects sorted by alphabet for Kconfig.
