drm/panel: simple: Fix innolux_g121i1_l01 bus_format

2022-09-28T09:32:14Z

[ Upstream commit a7c48a0ab87ae52c087d663e83e56b8225ac4cce ] innolux_g121i1_l01 sets bpc to 6, so use the corresponding bus format: MEDIA_BUS_FMT_RGB666_1X7X3_SPWG.

drm/panel-edp: Fix delays for Innolux N116BCA-EA1

2022-09-23T12:14:03Z

[ Upstream commit 8f7115c1923cd11146525f1615beb29018001964 ] Commit 52824ca4502d ("drm/panel-edp: Better describe eDP panel delays") clarified the various delays used for eDP panels, tying them to the eDP panel timing diagram. For Innolux N116BCA-EA1, .prepare_to_enable would be: t4_min + t5_min + t6_min + max(t7_max, t8_min) Since t4_min and t5_min are both 0, the panel can use either .enable or .prepare_to_enable. As .enable is better defined, switch to using .enable for this panel. Also add .disable = 50, based on the datasheet's t9_min value. This effectively makes the delays the same as delay_200_500_e80_d50.

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: 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
