The ST7701 and ST7701S are TFT matrix drivers with integrated multi protocol decoder capable of DSI/DPI/SPI input and 480x360...864 line TFT matrix output. Currently the only supported input is DSI. The protocol decoder is separate from the TFT matrix driver and is always capable of handling all of DSI non-burst mode with sync pulses or sync events as well as DSI burst mode. Move the DSI mode configuration from TFT matrix driver properties to common ST7701 code, because this is common to all TFT matrices.

2022-04-25drm/display: Introduce a DRM display-helper moduleThomas Zimmermann1-1/+2
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 <[email protected]> Reviewed-by: Lyude Paul <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2022-04-25drm: Rename dp/ to display/Thomas Zimmermann2-4/+4
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 <[email protected]> Reviewed-by: Lyude Paul <[email protected]> Reviewed-by: Javier Martinez Canillas <[email protected]> Reviewed-by: Alex Deucher <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
