drm/display: Move HDCP helpers into display-helper module

2022-04-25T09:19:36Z

Move DRM's HDCP helper library into the display/ subdirectory and add it to DRM's display helpers. Split the header file into core and helpers. Update all affected drivers. No functional changes. v3: * fix Kconfig dependencies v2: * fix include statements (Jani, Javier) * update Kconfig symbols Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-7-tzimmermann@suse.de

drm/display: Introduce a DRM display-helper module

2022-04-25T09:19:21Z

Replace the DP-helper module with a display-helper module. The support for DisplayPort becomes an internal option that drivers have to select. Update all related Kconfig and Makefile rules. Besides the existing code for DisplayPort, the new module will contain 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 the proliferation 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 namespace to 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

drm/bridge: anx7625: Support reading edid through aux channel

2022-02-14T12:42:05Z

Support reading edid through aux channel if panel is connected to aux bus. Extend anx7625_aux_dpcd_trans() to implement aux transfer function: 1. panel is populated in devm_of_dp_aux_populate_ep_devices(), so move anx7625_parse_dt() after. 2. Use pm runtime autosuspend since aux transfer function is called multiple times when reading edid. 3. No-op if aux transfer length is 0.

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/bridge: anx6345: Fix compilation breakage on systems without CONFIG_OF

2019-11-13T08:52:44Z

The driver assumes that the platform uses the device tree, and thus relies on some fields (of_node) being declared in some structures (drm_bridge). This isn't true for all platforms, so make sure we can only compile the ANX6345 on platforms where DT support is selected.
